Connecting an Antenna to Multiple TVs

For more information on watching your favorite TV shows without a cable subscription, check out our guide on watching TV without cable.

While you can watch local TV online, the best way is with an OTA antenna. Connecting one antenna to multiple TVs can sometimes be an ordeal depending on the signal strength in your area.  I’ve seen situations where all the TV’s work fine with their own indoor antenna, but once the outdoor antenna is installed, no TV can get reception.

These issues mainly result from improper installation of the coaxial cable and antenna cable splitters running from the antenna to the TV’s within the house. While simply connecting a bunch of coaxial cable might result in HDTV, often times it increases the installation time due to all the unnecessary signal troubleshooting.

This article takes you through the steps you should take to avoid the common mistakes people make when installing their antenna for HDTV. It took me years to learn this, but taking the time to install something properly will save time fixing mistakes in the future.

Step 1: Position the Antenna Properly

Before you worry about connecting the antenna to multiple TVs, make sure there is optimal signal strength on one TV. Connect the antenna to one television. Ensure there are no coaxial cable splitters in the line. A grounding block should be the only thing between your TV and the antenna.

Properly position and mount the antenna to capture the most TV stations on the one TV. TVFool.com can provide you with this bull’s-eye map indicating where the TV towers are located in your area. I’ve also put together an episode of the Grounded Reason Podcasts that walks you through using TV fool.

If they are positioned in multiple directions, you may want to use an omni-directional antenna like the Mohu Sky. I found the Sky to be the best small multi-directional antenna I tried, and personally use it myself.

However, if stations are situated in a single direction, perhaps a Yagi style antenna like the 43XG may be better for your situation.

Once you’ve ensured the antenna is properly set up, and the TV is capturing the channels you need we can move on to getting all of the TVs in your house on over the air high definition signals.

Step 2: The Coaxial Run

The first time someone installs an antenna, they typically think they need an amplifier. I made that mistake myself.  It’s not always the case, and in fact an amplifier can sometimes overload a strong signal causing reception issues.

So forget about the amplifiers for now. Consider it a tool for fixing reception issues should we encounter them later.  For this step,  we simply need  coaxial cable and a splitter.

Use RG-6 Coaxial Cable

The length of the Coaxial cable contributes to signal loss.  The longer the cable, the more loss the signal can incur. In the U.S. cable installers used to use RG-59. This cable is still sold and can be found within many houses in the U.S. I recommend staying away from this older coaxial cable and opt to use the RG-6U standard.

Use RG-6U for TV antennas

RG-6U cable has been shown to cut signal loss almost in half compared to the old RG-59 standard.  These cables look very similar. The cable type is typically printed on the outer sheath of the coaxial cable . The RG-6U cable is slightly thicker in diameter compared to its RG-59 counterpart.

Use the Correct Antenna Splitter

Each output of the cable splitter degrades the signal regardless of whether it’s connected to a television or not. A splitter with 4 outputs will roughly divide the original signal strength by 4 or 25%. Therefore, it’s wise to get a splitter where the number of outputs exactly matches the number of TVs you are hooking up. For more information check out my post on choosing the right coaxial splitter.

Avoid daisy chaining splitters.  In other words, if you are hooking up 3 TVs use a 3-way splitter instead of connecting the output of one 2-way splitter to another 2 way splitter. A 3-way splitter provides 33% of the signal strength to each TV.

However daisy chaining 2 splitters will provide 50% of the signal  to the TV connected to the first splitter in the chain, while the 2 TVs connected to the second splitter only receive 25% of the signal strength. This leads to an unbalanced configuration that can make troubleshooting difficult and create issues if you expand in the future.

Also be careful when buying a 3-way splitter. Some Are unbalanced where one output has less loss than the others. For example 1 port will has -7dB while the other 2 outputs show a -3.5dB. This is because the internal workings of the splitter essentially daisy chain a pair of 2-way splitters. A balanced splitter will show the same loss on all outputs.

Connecting The Televisions to the Antenna

By this point we know there is decent signal strength coming from the antenna from when we set up the first TV. Any reception lost from this point on is due to the equipment, namely the coaxial cable, splitters and digital TV tuners.

Before connecting any televisions, draw with pencil and paper where the splitter and cable will be run in your house. Then, measure how much cable you we need for each run.   Keep your cable lengths as short as possible as the longer the length, the more signal is lost.

Now it is time to install the first TV with the splitter. We will install the TVs one at a time and test.  This will give us an idea of what point the signal drops out for a given channel. Connect the line from the antenna to the splitter input and one output to a TV. Now test to make sure the TV can receive all the channels it could before introducing the splitter.

Continue Adding  one TV at a time to the splitter and test for channels. Keep adding televisions until they are all installed or, you aren’t receiving all the channels you should on each TV.  If at any time the TV can’t receive the same number of channels we may need to look at amplifying the signal, which I cover in the next section.

Do You Need an Antenna Amplifier?

Antenna Gain vs Amplifier Gain

Antenna amplification can be a confusing topic.  There are generally 2 types of signal amplification in regard to antennas.  The first is usually called “antenna gain.” This is amplification inherent within the antenna. It is a term mainly used when discussing directional antennas.

The gain being discussed with “antenna gain” isn’t really adding any power to the signal. It’s more of a representation of how well the antenna converts the signal wave to an electric current. Directional antennas concentrate that ability in one direction, hence sacrificing gain in other directions.

The other type of amplification, amplifies the signal after it is received. This typically referred to as “amplifier gain” and will not make the signal better than what it received by the antenna. Only antenna gain will improve  picking up a  signal from the TV tower. Amplifier gain is used to overcome loss in the line and noise from the digital tuners on the TV.

This distinction is important. If you can receive all the channels you need when hooking the antenna directly to one television, then amplification is only needed to overcome loss in the line.  However, if you were having issues before any splitters were introduced then we may need to look at purchasing a directional antenna with higher gain.

Which Amplifier to Use?

Amplifier gain is mainly delivered from 2 devices, a preamplifier or a distribution amplifier.  They essentially perform the same function with a slight difference. A preamplifier is installed at the antenna and amplifies the signal. A preamplifier should be used to overcome a long coaxial cable (over 100ft) in between the antenna and the splitter (or the lone TV).

A distribution amplifier is installed just before the splitter and is used to amplify the signal for splitting to multiple TVs. Some distribution amplifiers, like the one pictured below, also function as a splitter.

These amplifier both have similar function, but generally if there is a long cable run before the splitter, try installing a preamplifier to see if it fixes the issue. On the other hand, if you see loss not from the line but the splitter, you will want to try using a distribution amplifier.

Some situations may even require both if you are installing multiple TVs with a very long run of coaxial cable between the antenna and splitter.

To Much Signal Can be a Bad Thing

The reason we want to first try installing without amplifiers first is signal overload.  If the signal is strong from the tower, too much amplification can overload the tuner and cause the TV tuner not to receive the channel. Amplification should always be  seen as  a way to improve reception, not installed by default.

  • VERY WELL WRITTEN ARTICLE. Only one question, can I install TWO coax cables to my antenna, to service TWO TV's ? Would two cables connected to the same antenna degrade the signal strength for both ? THANK YOU .

    • Digital isn't like analog. As long as you can receive some amount of signal at the TV the picture will be high quality, so it's okay to lose signal when splitting the line. What you should do is run the antenna to a 2 way splitter, then run a coaxial from each splitter output to a TV. If you use an amplifier make sure you put it between the antenna and the splitter.

  • Great article. I have one antenna mounted near my garage in a rural area. I have coaxial cable that runs to my cabin approx. 100 feet from the antenna. I have great reception at the antenna but lose alot of the channels during the 100 foot run. I would also like to have a TV in the garage that is approx. 40 feet from the antenna. Any suggestions? Thanks

    • Situations like yours are perfect for an pre-amplifier. Stick one after the antenna and it should give the signal enough of a boost to make it through the run.

  • I used to have my HD antenna hooked up a 10-foot run to the TV and had very good reception, but the antenna was in a window and needed to be mounted on the roof. I ran a 100-foot cable from the roof-mounted antenna directly to the TV to check aiming, and had all the same channels as the shorter run from the window. The final run went through the 100-foot cable to a grounding block, then from the block through a 10 foot run to an amplified splitter. When I checked again, I had lost two channels. Should I look into a preamp, or will that cause too much of an issue in conjunction with the distribution amp? Could the grounding block be an issue? It is older (10-15 years) and has been exposed to the weather.

    • 100 feet is a pretty long run. You can use a distribution amp at the splitter and a preamp at the antenna. If possible, I would try to shorten up the cable length. Also make sure you are using RG-6 coaxial and not RG-59.

  • Thank you for providing invaluable advice. I've purchased the Sky 60 on your recommendation and now am deciding on which 4-way splitter to use. At the moment I'm using a configuration of a daisy chained 3 to 2 splitter provided by the cable company. I'd like choose the best 4- way splitter. Advice?

    • You can't go wrong when it comes to Monster. They are a great brand and I've never had any issue with any of their equipment.

  • I plan on hooking 4 tv's to one antenna and all will have about 60ft of coax cable. Would it be better to go with 2 antennas and only splitting the signal in half or is that overboard? I live in a big city so towers are less than 100 miles from me.

    • Hi Ron,

      I would try one antenna and see how it works with 4 TVs. If it's not acceptable try then I'd get second one. However, before buying the second, make sure you are happy with it working on 2 TVs.

  • I installed a TV antenna about 100' from my house in order to get on the station side of the trees in my back yard.

    I've followed all the NEC requirements for the installation, including grounding the mast to a ground rod at the mast, and a #6 copper bonding wire from that ground rod to the ground rod at my service entrance. The coax enters at my service entrance, and the shield is grounded just outside the house using a coax grounding block.

    My question is, would it be a good idea to also ground the shield of the coax at / near the mast using another coax grounding block. My concern is that a lightning strike could cause a lot of current to travel over the coax shield to the coax grounding block at the house, probably damaging / destroying the cable.

    • Grounding doesn't really do much against a direct hit. It's just too much energy. What grounding does do is protect against the EMF that occur from close strikes. That said, I don't think grounding near the mast would hurt if it's 100 feet away. Typically people have the antenna near their house as long coaxial runs can attenuate the signal, so I don't have too much experience with your type of setup.

  • I have a cable outlet on a roof top deck . Can a antenna be hooked up to that cable outlet and be used for 4 tv's

    • While that is possible, you want to make sure the run is as efficient as possible to get the most channels.

  • Hi Dennis,

    I am trying to hook a large house, (3 stories with 10 TV's) up to local OTA stations. For a job like this what antenna would you recommend? Is there special equipment needed for this many TV's? Also, can I still use the cable system set up in the house already? It has multiple splits as you would imagine to feed the TV's.

    Thanks,

    Steve

    • You can use the cable system coaxial, but you want to make sure you have a balanced split going to each TV. Odds are the cable system isn't balanced. You can try and see, but if it doesn't work you are going to need a distribution amp. For 10 TVs I'd use this one. You should take the 4 TVs that are closest to the amp and use a splitter on 2 ports off the amp for those. Then use the other 6 ports and run lines straight to the TV. That would give you the most signal.

  • How does tuning in to different channels simultaneously on multiple TVs effect the signal reception of a connected single omni-directional antenna? Thank you.

    • As long as you have enough signal power, tuning into different channels shouldn't make a difference.

  • Excellent article and easy to understand.

    I have one 4K TV (we stream only on this TV) which is our primary tv and two HDTVs that are rarely watched. When installing a splitter do I want a balanced splitter in this case?

    Thank you for your assistance!

    • I recommend a balanced splitter. It ensures the same signal power is transmitted through each line.

  • We purchased a Clearstream 4V antenna with tapered loop technology and have it installed on our roof with less than 50 feet to a Commscope SV-38G splitter that will connect 3 TV's. All 3 are HD compatible, one built-in and the other two have set-top converter boxes. We used the cable from our satellite dish to connect the antenna to the splitter. We tried one TV without the splitter first and only got 5 channels. We hooked up the other 2 and the 5 channels come in great on all. Our neighbor, who has the old fashioned outdoor antenna, gets at least 12. Any suggestions?

    • I would need to see your TV fool report to be sure, but it's possible that your neighbor is using a directional antenna which can direct gain toward a certain direction.

  • I live in a valley and want to get an antenna to put on my roof. Towers are on different sides of me so I think I will need an omnidirectional....also I want to plug into 2 tvs. What do you recommend I get? I bought an outdoor lava antenna and it seems very random. First I got 20 channels and once I hooked up other tvs I was down to 13. And now I'm down to 3 and haven't changed anything. I also plugged it back into just one tv without any splitter and only get 3 channels now? Does the weather effect these a lot? Any help is greatly appreciated! Thanks

    • Does the extreme channel loss happen when connecting it to a specific TV? How many channels do you get when you directly connect the antenna to another TV?

  • I have a RCA ANT702F amplified antenna that works great and picks up 36 over the air channels. However, I want to add 2 TV's to it. As soon as I hook up any kind of splitter; passive, powered, amplified, two channel, three channel, four channel, I have no reception at all. I don't just lose a couple of channels, I lose them all. Any suggestions?

    • That's a tough one. Something has to be configured oddly, or there is massive interference somewhere in the house. Do any of the cables run near a big appliance or other electro magnetic source?

  • I have a Winegard HD7697P antenna and want to drive 5 TVs. Is there a 5-way splitter to use?

    • Hi Bill, It depends on the signal power in your area, but I would get this distribution amplifier with 4 ports and a 2 way splitter, or the 8 port version. It depends on you having any long coax runs after the amp. The 4 port model will allow for longer runs because it adds more gain to each line. If you go that route, you should put the 2-way splitter on your 2 shortest runs.

      • Great website thanks,
        I am in the process of cutting the cord. I still have 3 months contract with ATT. Currently paying 190. 00 per month. I purchased a RCA indoor with amp a few months ago and messed with it a little but not much reception in the room I had it in. (Adding this TV to ATT would be additional cost. ) I took the RCA into the attic and are getting nearly every channel I want except one. Since this is just an inexpensive indoor antenna should I assume that the best outdoor antenna either in the attic or mounted would work with 5 TVs? I must have a pretty strong signal. I'll check out your reviews and other information.

        • 5 TVs is possible. It really depends on how much signal power you have, and how efficient your coaxial wiring is.

  • I have a homemade antenna in my attic and I have it ran to a 2 way splitter that runs to my living room 40' away and my bedroom 70' away. The one in my room is getting 28 channels but my living room won't pick up none. Can you tell me why. Thanks.

    • Hi Blake,

      I would try switching your splitter outputs to see if the living room TV gets any channels. If there is no change then it's either the cable on the tuner on the TV. In these situations I try to isolate the issue.

      Let me know if you have any questions.

  • Hi, I am in Brunswick Georgia and currently pick up channels from both Jacksonville Florida and Savannah Georgia with a Lava 8008 omnidirectional antenna and am able to pick up 15-30 channels depending on the weather. I purchased a DB8e Extreme Long Range Bowtie HDTV antenna and a Juice amplifier. I will mount the amplifier on the antenna mount. I need to feed 5 televisions. The Lava will only feed one TV however that particular TV will also need the Bowtie antenna to pick up Jacksonville Florida channels better. What will be the best splitter setup so that the Bowtie can feed all 5 televisions and the one TV can combine the Lava and the DB8e?

    Thanks, Roger

    • Is the Bowtie antenna indoor? If so I'd put one on each. It's difficult to split an indoor antenna in most instances.

  • Hi,
    Great info and help I see here going out. I have CM-4228HD with approximately 60 feet or less run, (hard to straighten the run out to measure), with a 1 way splitter. The upstairs TV only pixilates a little on some channels, (I assume the downstairs simply has a slightly better receiver). If I remove the splitter and go cable to cable to upstairs, I receive over 50 channels, no pixilation on the desired channels. Add the splitter and there are 30-some channels but most importantly the pixilation is back. I assume this says the signal is there but needs an amp before the splitter; but I know how to spell assume. Is there a low power amp (7db-ish OR what do you say? Thanks in advance.

    • Yep, a Pre-Amp before the splitter should compensate for the noise caused by the splitter. Let me know if that helps.

  • Thank you for this website! I am gathering information on "cutting the cord".

    1.)Can I install an outdoor antenna and connect to the entry point of the existing coaxial? (Currently used by my cable company to provide bundled service)

    2.) Would I need multiple antenna in order to connect multiple TV's?

    3.) Is there an amplifier which could be used at the source (if the signal is degraded)?

    All of my rooms are wired internally with coaxial cable (circa 1986).

    Thanks so much!

    • I would only recommend using the existing cable if you don't need it for internet, and you know how it's run. Too many splitters can cause reception issues. I recommend multiple antennas if you are using indoor antennas, one outdoor is typically enough for a few TVs. An amplifier is only needed to correct issues, I'd try installing without first.

  • We had satellite tv. We changed to an hdtv antenna. We used the existing splitter and coxial cables from the satellite hookup. We get excellent reception on the upstairs tv but cannot get signal on the tv downstairs. This tv has a coaxial run of aproximately 50 ft. What do we need to get signal for the 2nd tv?

    • I would check to see how many splitters are between the antenna and that second TV. It's possible the TV with reception is off the first splitter, where there are more splits on the way to the second TV.

      • I am not very knowledgeable about this. There appears to be one splitter attached to the outside of the house. It has one thing on one side and four on the other. I believe we left the coxials attached where Direct had them for the 2 tvs

      • I am not very knowledgeable but the splitter is one that was left by Direct tv. There is one thing on one side and four on the other. We left the coaxial connected to where Direct had them connected.

  • Hi, I have a LAVA HD2605 Ultra G3 Motorized Outdoor HDTV UHF/VHF Antenna which is hooked up to 3 TV`s and it works great but sometimes I will lose signal to some channels for a while and than they will get the signals back it`s always the same channels. Do I need an antenna amplifier to keep the signal coming in to these channels all the time?

    • I would need to see your TVFool report to get a better idea, but if you can pick up the channels occasionally, then a 5-10 db gain amplifier may be enough to compensate for the line noise.

  • Great article, well written. I am installing a directional antenna and the the two cites I want to receive from are approximately 60 degrees apart one much closer than the other. Do I split the difference and aim in the middle or do I am more toward the further away station. Also does the pre-amplifier help with bringing in weak signals due to far away towers?

    Thanks for your help.

    • An amplifier won't help you receive a signal that isn't reaching the antenna. It's used to boost the signal after it's received to compensate for line noise from the tuner, splitters, and cabling. The best solution would be to get an antenna rotator so you can direct the antenna from inside the house. 60 degrees is going to be to wide of a spread to take advantage of the gain from a directional antenna. You might as well go Omni-directional as opposed to splitting the difference with a directional.

  • Great article I live in area between to larg markets. We like west (south bend) channels and east (Ft Wayne ind. ) channels. If I have two antenna's one each direction how can I easily switch back and forth for each of my 3 TV,s

    • Can you post your TV fool report? It's hard to say without knowing the station power.

  • Hi
    I bought the lava 2605 ultra antenna 360 rotation amplifier we installed it at the highest point on the roof and we are not getting any channels we got one when we tested the antenna in the house while the Antenna was laying on the floor and we got our local channel cystal clear what am doing wrong we should get at least 13 channels not zero help me please c

    • Something be wrong with the wiring. Is it one line to the TV or are there splitters involved?

  • Great article. I have the Mohu Sky 60 right now and am in the process of trying to install it. I will be splitting it two at least 2 TVs. The manual states to use the Mohu preamplifier with the USB connection before the splitter. What is the best way to use this with an attic installation. Looking at maybe a max of 50 ft. run to the farthest TV

    • Put the pre-amplifier between the antenna and splitter. You can power it with a USB power adapter

  • Dennis, NYC is only 34 miles away, where Philadelphia is 63 miles away. I am a Philly sports fan, and would love to get the Philadelphia Eagles NFL games on Philly FOX. Any suggestion on how to get both the NYC stations and also the Philly stations. Would I need two antennas? If so, which ones would you suggest? (Sorry if this is slightly off topic of splitters and amplifiers)
    Thanks for your response.

    • I would need to see a signal report to be sure. If you want to run the one at TVfool described in this post I may be able to provide some guidance. It's tough to say without knowing the signal power coming from Philadelphia.

  • Dennis,
    Great article and excellent comments and replies on Grounded Reason.
    The TVFool report for my address shows one set of stations south and another set north, equidistant from here, ~180 degrees off. An indoor antenna would pickup one set or the other, depending on which side of the house I placed the antenna. So I installed a Clearstream 2V on the roof where it has unobstructed north and south views, except for trees. Its about 50' of cable to the nearest TV.
    I got good reception, about 18 channels from each market to one TV. However, I get pixelation and signal loss during windy/rainy weather. We're on a hill, so should this short antenna mast be plumb or follow the terrrain? How sensitive is a directional antenna to elevation and compass direction?. Is 10 degrees off a lot? I'll get back up on that ladder if I must.
    Also, existing cable lines are home runs from an outdoor service point. If I need an amp for 2+ sets, what outdoor amp is best value?
    Thanks for your reply.

    • Being on a hill is fine. It should give you better line of sight with the tower. The higher the better. As for a new antenna, you may save yourself some money by trying to stabilize your current one. Is there a way you can make it less susceptible to wind? As for the directional antenna, the focus of the gain varies from antenna to antenna. The spread should be listed in the antenna specifications.

      Also, when it comes to amps. I think Channel Master makes a great product. They have 2 and 4 port distribution amps.

  • I have installed an outdoor hdtv antenna with about a 50 ft run to a splitter. From the splitter it he coax goes to two tvs. From splitter to tv one is about a 10 ft run. I receive 98% signal strength at this tv according to tv diagnostics of antenna level. To tv 2 it is about a 40 ft run from the splitter to the tv. I don't receive any signal at tv 2.

    My question is would adding a distribution amplifier in place of the splitter cause the signal strength to be too high at tv 1 where I already receive great signal strength? If so, what would you recommend?

    • It's possible, but I'd have to see a TV fool report to be sure. What happens if you run a line straight to TV2 without a splitter? That would give you a good indication if the tuner on TV2 is causing an issue.

  • Dennis...Thanks for helping us DIYers with the set up of OTA TV. I have an Antennas Direct DB4E antenna up at 25 ft., along with a Winegard pre-amp and a distribution amp for 4 TV's> I am achieved some success with the install but I feel it can be much improved. The first thing I need to do is shorten the cable between the antenna and distribution amp (currently 100 FT). Based on what I read on TVFool, I should be able to pick up about 40-45 stations. I am in CT between NYC and Hartford, CT. at 06611. Questions: When aligning the antenna should I use True or Magnetic North? Since the antenna has (2) directional components, should I aim one SE (NYC) and one NW (Hartford) or is it better to aim them in the same direction? Also, I would like to add a 5th TV, is my only option a larger amp (currently 4)?

  • I wanted to know if the TVOne antenna I believe that's what it's called works. I have one tv. There's cable in the apartment just not in my room. How can I watch cable since the service provider is digital?

  • Thanks for the tips, Dennis! I am also wanting to cut the cable in our home. We have 6 cable jacks in the house (of which 3 are actually used) and I would like to run a single Mohu Sky to all of them so they're available in the future if I want to utilize them. I would like to set up a Sky in the attic, run an RG6 from the sky to the media center in the basement approximately 100' away terminating into a distribution amp like this one, and then going from the amp to all the jacks in the house. My questions are: By using the distribution amp would I still have to use the amp provided with the Mohu Sky? Would using 75 ohm type F terminators on the unused jacks or splitter outputs preserve my signal to the outputs I actually will use? Some additional info, I am in Illinois, so its flat as can be and I am within 28 miles of any channels I care about according to TV tool. - Thanks

    • I'm usually hesitant to use multiple amps. You can test it and see, but I would stick with just the distribution amp. The split happens in the splitter, so even capped they still attenuate the signal.

  • Great article and posts. I have a situation where my splitter is on the outside of the house. I am needing to add a preamp but the splitter would be between the antenna and power supply. I have heard about using either a voltage block on one port of the splitter or using a one port power pass splitter. Any recommendations on how to proceed?

  • Dennis, Article and form answers are great. Here is my situation. I've had a large outdoor directional UHF/VHF antenna, using a rotor on the roof for years. Last six months or so channels have been dropping frequently. I bought a Channel Master 4228, 80 mile omni antenna and have placed it in the house temporarily pulling in most channels except it still drops Fox 11 which is a Hi-V station. Most of the other channels are listed as UHF. I live in zip code 54929 about 50 miles from Greenbay Wisconsin which means I am on the fringe of the broadcast signals. I am going to order new cabling to replace the coax that is probably 20 years old. The old antenna use to hold stations pretty good except when weather was bad. I suspect something has come lose, corroded or damaged. I plan on climbing up there when weather permits. My question is, can I attach the omni directional antenna on top of the directional one daisy chained. Channel Master suggested their top of the line diretional 100 mile antenna and a pre-amplifier at the antenna. The old antenna seemed to work pretty good all these years but the second TV and third one occasionally used upstairs rarely pulled in all the stations and dropped stations. I hate giving up on the omni one I just bought. Maybe I should just connect two antennas, each to separate TV's? Would you suggest I try an amplifier on the old antennas? Or return the new one and purchase the directorial 100 mile antenna. I liked the idea of pulling in all of the stations without turning the rotor and thought the Omni would solve it. .The distant towers are only about 10 degrees apart.

    • Hi Don, Daisy chaining the antennas will cause the antennas to interfere with each other. It's possible if you have an antenna that does UHF well and then an Antenna that does VHF well to jet a UHF/VHF signal joiner that restricts each antenna to a certain band, but that's an answer to another question. As for your question, with 10 degrees between the towers I doubt you would be moving the antenna all that much, so a directional should be fine. However, after looking up your zip code it looks like you have strong signals coming out of the south east for all the major networks. I'd try the Omni with the new cabling before buying the directional. I doubt you would even need a pre-amp. Let me know how it goes.

  • Im thinking of running an antenna in my attic and splitting it to two TVs. What antenna would you recommend for that and is grounding necessary since its in the attic? Im in Austin and the transmitters are not too far away, say 10-15 miles at best. Since I am splitting the signal should I amplify it as well?

    • I didn't see anything in the code regarding an attic installation and grounding. There is always much debate on antenna forums on this question. Personally, I would err on the side of caution and ground it anyway. If you want peace of mind, I'd ask an electrician in your area. They would have knowledge specific to your area in regard to the amount of lightning you get.

        • Sorry about that Matt. I got caught up in researching the attic installation that I forgot your other question. I personally like to put a small amplification on the wire when I use splitters or have a long coaxial run. It will compensate for the added attenuation.

  • Great article. When running the antennae line into the house can I connect to existing cables and splitters installed by the cable company? This would save me a lot of time and effort.

    • You can and it may work, but if they split the signal too much in may impact reception.

    • Amps only compensate for noise in the line really. If you are doing multiple splits then Id recommend a distribution amp. I've never tried 2 preamps though.

  • if mohu sky antenna is installed in attic/crawl space, where does the coaxial cable go? Through the walls, across the ceiling, or what? i am hiring someone to set up antenna to feed 3 tvs, but i cannot imagine where the wiring goes? Would it be better to use my cable connections/wiring already set up? How does antenna cable connect to cable company wiring (co axial)? I want to understand what I am hiring this person to do. Thankssa

    • If you are not using the cable TV coaxial, then you can use it for the antenna. Be warned though, if it's an inefficient install of the coaxial it could impact your reception. But you can think of this much like you would as a fresh coaxial install for cable, except instead of the feed coming from your cable company, it's coming from your antenna.

  • I am in a townhouse which has 2 tvs downstairs which work perfect The antenna is inside the manhole upstairs What can I do to get the upstairs TV up and running I'd be so grateful for your advice Judy

    • Hi Judy,

      I would recommend replacing the 2 way splitter with a three way and see if the 2 TVs still work. If they do then you should be able to add a third TV. If the signal drops after hooking up the third TV then installing an amplifier should remedy the problem. Every situation is different, so its hard to give advice without knowing how your coaxial cables are run and the signal strength in your area.

  • Great article and great responses to these questions!

    Right now I'm using an outdoor antenna that's on my Shed that was here before I bought it, It's at least 10-+ years old. Hooking it up to a small cable right to the shed I get plenty of channels(Whats crazy is AntennaWeb doesn't mention most the channels i am getting):

    8.1/8.2(CBS)
    10.1/10.2/10.3(NBC, 66miles away)
    19.1/19.2/19.2(ABC, CW)
    25.1/25.2(Fox)
    31.1/31.2/31.3(PBS)

    Now hooking up to even a 2 way Splitter cuts everything except CBS, Since I get everything in the shed fine, Assuming I need an distribution amplifier as I'd like to use 3-4 TVs.

    Next is, once I have a line run to my main TV I still get all my channels, but it's hit and miss, sometimes I get them all sometimes only a few, bad weather only 2. I'm assuming this is because of the long cord, and also I'm using a cord that was ran under my place from years ago, it's an RG-59 cable. I plan on getting the RG-6 cable to replace it just making use I have all the right setup when I do it so I'm not wasting money.

    So based on my losing channels sometimes and during weather is my best plan to get the distribution amplifier as I get all channels in the shed but lose channels based on distance/splitters?

    And #2 what is my best plan for aiming/amps to make sure I get CBS/NBC/FOX. I'd obviously like as many channels as once but want CBS & FOX for NFL and NBC if I could also for NFL.

    Thanks

    • If everything comes in fine on the one TV then adding a distribution amplifier should help the situation. Since you are getting ABC I'm assuming you have a directional antenna with a bit of gain. I would point it about 12 degrees east of true south. That should get you the bulk of the channels. Let me know how it goes.

      • Thank you for the quick response, once this rain goes away and my amp comes in I'll be sure to give it a try, I'll let you know, thanks!

  • Thanks for all the wonderful help.
    I know it's not a common request in USA but I am a fervent soccer fan, and especially the UK Premier League. Do you have any suggestions for how to get Premier League matches after cutting the cord?

    • I'm still looking into that myself, when I find a solution I will be sure to post it.

  • I have a directional antenna with an amplifier on the antenna. I get 9 channels on three tvs most if the time, otherwise they cut in and out. I decided to try a 4-way signal amplifier but when I hook it up, I lose all channels. Why does it work with the regular 3-way but stop working when I hook a 4-way amplifier?

    • That makes sense. You're splitting the signal 4 ways as opposed to 3. Even if you don't use the 4th output it still counts as a signal split and each line with get 25% of the signal power received by the antenna as opposed to 33%. Assuming everything is installed correctly, the added split in the signal may negate any benefits provided by the amplifier. You may be better off just using the 3 way split with a preamplifier between the antenna and splitter.

  • I just installed the Mohu Sky60 running 3 TVs. I am using one 3 way splitter with the amplifier supplied in the kit before the splitter. I am happy with the reception except for 1 thing - I lose CBS once in a while. I don't know why, because some of the other channels come from the same location CBS does. Do you think it would help to have 3 amplifiers ? ( One in line just before each TV ?

  • I have one tv upstairs and one downstairs. Can I just get 2 leafs and put one with each tv so that I can get basic channels on each?

  • I currently have dish network and want to switch two Antenna tv. Is it possible to use my cable from my dish. Currently dish goes to two tv's, would I need a splitter?

    • You can use the existing cabling, but it should already have a splitter installed if it goes to two TVs.

  • I'm looking at a 2-way splitter to share the signal from a directional roof antenna between TVs. I've seen both 1 GHz and 2GHz splitters in the store. Is there anything to choose between as far as what splitter to use? Also, is there any useful meter test to check signal strength, or is it just a question of how it looks? Trying to decide if I will need any amplification.

    • Existing TV is a Sony Bravia, and the one I'm about to add with the splitter is a Vizio E241. I understand that a splitter will make for about a 3.8dB drop in signal, but I don't know how much that matters. My question is about whether the TYPE of splitter matters: 1 GHz vs 2 GHz. I definitely have signal going to the Sony, but have occasional interference or pixillation, possibly from multi-path signal--I don't know. See other question. Does it matter which splitter I choose?

      • Sorry about that. All TV frequencies are under 1GHz so the 1 GHz is all you need. All things equal, there shouldn't be any improvement from a 2 GHz splitter.

    • Many TVs come with a way to check signal strength. What type of TV are you using? As for the splitter, that will split the signal power in half for each split. You can typically compensate for it by using an amplifier. However, make sure you can get the reception to one TV before adding a splitter to the mix.

  • I have what should be an ideal location. In SW Mpls nearly all the channels are clustered 13 miles away, in a spread between 43 and 46 degrees to the northeast. I have a mast-mounted Winegard HD 7694P pointed about 44 or 45 degrees. Most reception is very good, except that under some conditions I get freezing and pixillation. There are lots of trees in this part of town, and we are in the flight path of the airport, so I figure some of it might be multi-path interference. Also worse in humid or rainy conditions, so maybe the signal is finding lots of ways to bounce. Any way to figure out what's going on? Any suggestions? I also submitted a question about adding a 2-way splitter. Will that make my problems better or worse?

      • Are the channels giving you issue Fox and NBC? If so it's most likely because they are Hi-VHF. VHF is a little more susceptible to multi path interference. I doubt the amplifier would help much, but I've seen stranger things work. You could give it a try. Is there anything shadowing the antenna from above, like a tree canopy? If so try lowering the antenna. I know it seems counter intuitive, but lowering the antenna may pick up signals bouncing through the bark. Your TV fool is strong. You shouldn't be having these issues. Did you check out this article on TV antennas. It goes into detail on what I know on preventing signal loss.

    • I know you most likely have this correct, but I need to make sure. Make sure the short elements are pointed toward the stations. Many people make the mistake of thinking the long elements are in the front. Do you have a TV fool report you can share?

  • I loved your articles! I get great signal to my first tv but the tv that is further away will not pick up the same stations I am wanting. So it appears to me that the further tv needs an amplifier. The splitter is near the antenna. So how can I use and amplifier for just one tv so as not to mess with the other tv that is working fine?

    • I would put the amplifier before the split. That way it compensates for the attenuation in the splitter as well. If it causes issue with reception on the working TV, then I would try it after the splitter.

  • This is one of the best articles on the topic. Simple and easy to follow. Helped me fix some issues with my OTA multiple TV situation.

  • Great article. I have an opportunity to acquire another antenna similar to the one I have and would like to mount on my tower. Half of the stations I receive are to the north and half to the south, all about 60 miles away. I have a rotor but with 4 TVs it would be nice to get all of the stations all of the time. How do I wire them together? I have a Channel Master CM-7777 at the tower just below the antenna.

    • Unfortunately you can't use both antennas together in the same Band. You could get a signal joiner that filters the bands and use one for UHF and the other for VHF. Simply joining the two together will cause a lot of interference.

  • Hi,
    I am at my wits end. We cut the cable. Started exploring OTA antennas. Purchased the Clear stream 2V. It is mounted on top of the house at about 20 ft. Get good reception about 26 channnels including FOX and CBS. We were really hoping for ABC and NBC as well. Neither of them come in at all, even though everything says that they should. Here is our TVfool report:
    TV Fool
    Only hooking to one TV. No splitter. About 50' run of cable. Everything I've tried everything, still no ABC or NBC...Any ideas? THANK YOU!

    • Hi,
      Thank you for your reply. Yes, have pointed the antenna to the NNE direction, AND have tried the Juice preamp from Clear Stream. I just don't understand it. Everything shows that I should receive ABC and NBC, but I only get CBS. Thank you for your input.
      Kim

    • Does pointing the antenna NNE help any? If not, have you tried an amplifier?

  • I recently installed an antenna on the side of our house. I have fiddled with the location and found that I can get the most stations in my current spot. I thought I was all set getting the local stations I needed ABC, FOX, CBS, and NBC. All of them work great except I have been having issues with NBC (2EDGE path) from time to time which from TV fool report is only 15.2 miles away ( I have a GE 60 mile antenna). I have a pre-amplifier installed and a 4 way splitter attached as well for each room in our house. I have ran a 100 foot RG6 cable along the side of the house. The pre amplifier I am using is the 1byone low noise 20 DB. Any suggestions would be great for clearing up my NBC issue! Thank you,

    • Is the NBC channel in the VHF band? Also, what antenna are you using?

  • I have a Lava 2605 outdoor antennas. It seems to get good signal in general but we have alot of cutouts. We also are using a distribution amp but it cuts out with or without the amp. I will have a 8-9 signal then it drops out to 6 or5 and many times the picture goes off. Sometimes I get a signal that stays on but we still get many cutouts regarding signal.

    Is this interference and can i buy an interference filter to stop this? Seems to cutout on all channels and sometimes it cuts out and stays off and then comes back on with good signal after a few minutes. We rotate this for the best signal. getting tired of this!!

    • Where is the antenna installed? Is there anything around the antenna that could be a potential source of interference, like an AC unit or something similar?

  • I have installed a Lava 8008 antenna in my attic. The TV that is connected to the antenna is on the third floor. The RG-6 cable is run from the antenna to the wall outlet ( 25 feet of RG-6) Then another 25 feet of RG-6 and the inserter that was received with the antenna, to the TV. I receive a good signal for 60 channels. I am trying to send the signal to two additional TV's, one on the second floor and one on the first floor. I have a box on the first floor which the house network and TV wiring is routed. The routing I will be using is from the antenna in the attic through a splitter to the TV on the third and to the first floor equipment closet. From there it will be routed back to the second floor to a TV and a cable routed to the TV on the first floor. Should I use amplifiers in lieu of splitters since on the third floor and the first floor? If so which ones? Or do you have a better idea.

    • It depends on how strong your signal is. I'd try the splitter because they are cheap. If it doesn't work, then go with distribution amplifier.

  • I bought a HD-2605 antenna. It is connected to three TVs. Two of the TVs are identical brand and model and work fine. However, my Samsung TV receives the same amount of stations but everyone channel is choppy and pixelated. I'm thinking it has something to do with the TV. Any suggestions on how to correct this? Thanks.

    • To troubleshoot the issue, I'd see what happens when you directly connect the samsung TV to the Antenna.

  • Hello,
    I just read thru all of the questions and answers, and the information will help me setup my Antenna.
    Thank you for your time, great information.

  • I would like to get on your list. I have issues with my tvs reception.

  • I have good signal when connected to first TV, but when I attempt to use my
    three way splitter I lose signal completely. Will an amplifier fix this problem? Thanks

    • It should. The fact that you get the signal with one TV indicates that the signal is strong enough. You just need to put an amplifier before the splitter to compensate for the attenuation from the splitter which is about 10.5 dB. So you'll want an amp with slightly more more power than that.

  • I have an exterior antenna pole mounted and get great reception to 4 tv's... I Just added an out building and will have 3 more tv's... currently i have a channel vision amp boosting my signal to the 4 tv's... i was thinking about splitting the signal after the antenna but before the amp and adding another amp for the 3 tv's in the outbuilding. So there will be only 1 amp per run, but split after the antenna... thoughts? should i just put up a second antenna?

    • I would use 2 antennas. Be sure to look into using a distribution amp.

  • I have 3 TVs in the house. One splitter. 2 of the 3 TVs work fine - get all the OTA channels. But one TV loses signal or shows a low signal message on a few channels intermittently. I have swapped connections at the splitter end - the troubled TV still has the same issues while the over 2 TVs are still fine. I have moved one of the good TVs in place of the bad TV and the good TV still works fine using the bad TV's cabling. It seems to me there may be an issue with the TV itself or the coax (ANT IN) connector on the bad TV. Are there settings in the TV itself that I can adjust? Or is it possible to replace the coax connector on the bad TV? This TV used to work fine when it was connected to a Comcast set top box. I don't recall now but I assume at that time the cable signal was not coming in through the ANT IN port. Maybe there is another device that I could connect between the antenna and the TV that will convert from coax to an HDMI connection into the TV? Thanks in advance.

    • It sounds like the tuner in that TV may kick out a bit more noise than the others. Are you using a Pre-amplifier? It may boost the signal enough to compensate for the noisy tuner.

  • great article! I am beginning the process of cutting the cord. I have purchased 2 different amplified antennas. to see which will work better. I have 3 tvs in different corners of the house. both antennas give the diagram of putting the amplifier unit near the tv and using a long cable to the antenna. My question is should the splitter be before the antennas amplifier or after. It seems that I would want the split after the antennas amp. and then run my lines.

  • Great Job you are doing for the public, Thanks on behalf of all of us.

    Now... What OTA do you recommend and/or how many OTAs would I need to run 40 TVs assuming that my noise of margin is 20DB off the OTA?

    • 40 TVs is a very tall order. I would recommend seeing how many TVs you can get to work with a given antenna and try to scale that out. Take a look at my updated TV Antenna guide to figure out which antenna is right for your situation.

  • I want to run an pre amp on the antenna and am confused.Can the power for the amp be hooked up to one of the coax lines after the splitter? Reason I ask is I don't have any power where the coax comes into the house and would have to have the power connection by one of the tv's after the splitter.

    • You want to go before the splitter. The preamp will compensate for signal loss in your cable line due to the splitter.

  • I have just installed a 150 mile antenna and have picked up 32 stations. I pull from 85 miles away but when I split my signal I lost all channels so I added a Channel Master 4 port signal amplified splitter and now have 3 local PBS stations that I could get with rabbit ears. I called Channel Master and they told me I lost my other stations because I have too much power. Do I have the wrong kind of amplifier?

    • If the amplifier is too strong it will overload the tuners and you won't get the channels. However, I don't think that is the issue here. While a 4 port amplifier will amplify each line it also splits the signal 4 ways. Even if you don't use port, it still counts. You're essentially down to 25% of the original signal on each line. Try a 2-way splitter with a 5 mbps amp and see what that does.

  • My Sharp Roku TV is connected to an antenna which I made out of a bicycle rim. It is attached to a 30 ft pole. I had been getting great reception, abc, nbc, cw, grit, about 30 channels in all. 2 nights ago I lost all but three PBS stations. They still come in great. Any idea what could be happening? Maybe the tuner blew, but why would I still receive three channels?

    • That's a tough one. Typically when this happens there has been an change in the environment around your house. Are there any new devices that could be causing electromagnetic interference?

  • I have an indoor antenna connected to one of my tvs and it has a great signal. I used a two way splitter so the antenna is now connected to my tv and a previous cable line which is connected to another 4-way splitter in which only two of the lines are being used so the signal is sent to my two additional tvs. On one of those tvs the signal is great on the other I have significantly fewer channels. Do you think if I swapped out the 4-way splitter for another 2-way it will boost the signal so all 3 tvs will receive all the channels? Or do I need an amp?

    • The 4 way splitter, will split the signal 4 ways whether you use them or not. Therefore, a two way splitter should be a marked improvement.

  • I really want to cut the cable. I have a central alarm, phone, tv "box" in a closet in my home. The "box" has cable that runs throughout the house into every room. At the end of the cable "run" is a wall plate with a coax connector. What I want to know is will I need to put an amplifier at the end of each room that has the plate and coax connector in order to provide optimal signal strength or can I place an amplifier in the box and another close to the antenna itself? As you can see, my concern is the quality of the picture that I would get at each TV. Additionally, since these kinds of set-ups are more and more common today, has anyone done what I would like to do?

    • I wouldn't use existing wiring unless you know it's optimal for a TV antenna. As for your question, I would use an amp before the splitter. If you have multiple TVs consider using a distribution amplifier.

  • I hooked up 2 antennas with a splitter. The wire then goes into a amplifier. Then goes through a 4 way splitter to 4 TV's. I am losing 8 channels, these 8 channels are at a 70 mile distance.

    With just 1 antenna I am able to receive all 21 channels without the splitter.. But I am losing channels when I connect the splitter to only 1 antenna?? Why is this splitter for the 2 antennas causing me problems?

    • A splitter splits the signal in have whether it's hooked to another antenna or not.

  • Hello Dennis , what a great service you are providing here. Here's my question. Is it indoor antenna here in Chicago I was getting 70 channels. I switched to 60 mile range outdoor antenna on the roof about 10 feet above the roof line. Now when I do my scan I get about 35 channels and the signal goes from 95% down to 4% and it fluctuates from there back and forth from 95% down to around zero. What could be causing this? Thanks for your response

    • Dennis you're the man!! When I hooked up the other tv now all tv work. What I think was going on was the co ax Cable that was not hooked up was laying on a power supply. It was probably generating a little electricity through it that's why the fluctuation of singable the AC current

    • Hooked up another tv and it works fine got all 73 channels!
      So here's what happened.... cut the direct tv out hooked the antenna up to same coax system. The installation was about 16 months old so I'm confident in it. I'm just outside of Chicago less than 15 miles from any tower. There's a 4 way splitter that I'm sending the antenna through to my televisions.

      The maun tv worked fine with bunny ears. Now hooked up to Antena. Signal drops rapidly and bounces back up. The tv in the bedroom stays at a solid 94%

    • Yes all channels. You can see it as you watch the television freezes every 30 seconds

    • Are all channels fluctuating? If so, can you try another TV. If you have the same issue on both, then it may be environmental.

  • I have charter spectrum internet and bought a antenna with a 4 way splinter to put in the attic for tv. Every time we hook up the antenna the internet doesn't work. Please advise

    • You can't use your internet cabling on the antenna. You need a completely separate coaxial installation for each.

  • Thank you
    Your articles are as comprehensive as stated. As a marginal handiman , I believe I can cut cable and get local TV channels.

  • I am learning!! I want to cut the cable and will have someone install a MOHU Sky 60 in the attic (that was sprayed with radiant barrier) to connect to the current Uverse/2009 builder coaxial through out the house with 5 rooms...I am 50 miles from almost all stations. I tested with one TV with MOhu 50 and works really good. I just tacked it to a wall.
    What equipment would I add to record OTA shows? I imagine it would connect to each each individual tv.
    Thanks much for this senior....
    Joy

    • For several years, we've used "WIN-TV", a USB device with a Coax (Antenna) input on the other end, which allows your computer to act as a DVR. Costs from about $60-$80, depending where you get it. You do on-screen programming, just like a regular DVR. It also has rewind / pause functions for live TV viewing. Note - A one (1) hour program in the best HD quality will use about 6-8 GB of space, so you may want to pick up an External Hard Drive or "Passport" as a recording storage location.
      The software also has a local-station guide that you can view and record from as well.

  • I'm installing a mohu sky 60 using some existing coax from previous cable service. There's a 20' section of rg59 that runs through a ceiling, would be cost prohibitive to replace. Is it worth it to run the good stuff on either side of it to minimize loss, or should I just find another route. Will be going to 2 tvs with about 15'after the split.
    Thanks!

    • You would have to experiment. From an installation perspective, it's always better to do a fresh install to ensure it's optimized for antenna reception. However, as you said, that comes with a cost. If you're goal is to get reception without any up front expense, I would use your existing equipment. If you are happy with the result, then there is no need to update.

  • You're doing great work here!
    Thanks for all you do.
    I think I have a simple question.
    Can RG-6 be ran through conduit or around beams and other obstacles without interference of signal?
    IE; wound around the exterior antenna pole.

  • I have an indoor antenna with an amplifier. We moved our main tv across the room and plugged it into another cable outlet and now it won't pick up any channels. But when i move the antenna to that tv then the other tvs wont work. I have a splitter with 6 outs for 3 tvs should i get a distribution amplifier or smaller splitter or is it something else? Thanks

    • Yes. Those extra splitter ports will weaken the signal whether you use them or not.

  • I receive a decent signal with antenna connected directly to one TV. When I use a 2 way splitter to two TV's I get really reduced reception. My 2 way splitter is located outside in a water proof 4" electrical box and the runs to the 2 TVs go from there. Using a powered amplifier before the splitter will be extremely hard as running power to it is not easy. Will using an amplifier after the splitter work. I am aware I would need two amplifiers one for each TV if it will work. - Thanks for your help.

    • It really needs to go before the splitter. Otherwise you will just be compensating for the TV turner noise on the line the amplifier is on.

  • hi i have a problem with my installation.

    Heres my setup:
    I have my antenna going to a 6 way splitter in the ground floor and from this splitter it connects to another 6 way splitter on the 1st floor. I have an rca to rf converter that converts my tv box signal to an analog rf which is then used as an input on the splitters. On the 1st floor i have 4 crt tvs connected and they all show the signals fine (both using the analog signal from the converter and using the digital signal from the antenna in a dvb-t box).

    Heres my problem:
    When i try to connect another crt tv on the 1st floor, i get a black and white signal on that extra crt tv and the other tvs are fine. The crt tv is of course a colour one and i have tried 3 different tvs.

    Is this something to do with my setup or with the tvs?

    • The signals will interfere with one another. You can use a signal joiner, but you would need a filter to control which channels come from each antenna.

  • I have a Mohu Sky 60 that is approximately 15 in the air on the eve of the house. I've used TV Fool and know that the stations I'm wanting to receive are about 90 degrees apart. 1 station is about 25 miles away the other is about 40 to 45 miles away. I've tried splitting the degrees to get all channels but since the leaves have come out I can no longer get the the farthest station. I am using a 30 dB preamplifier at the antenna. I was thinking of using another antenna to get the other channel and combining the two. Any suggestions?

    • We are planning on cancelling our sat svc very soon and are trying to decide on an antenna. My situation is the basically same as Shane's, although we will put our ant on the roof. TV Fool shows our LOS stations are all under 40 miles away. . most are in the same general area, but some fan us out on the bullseye map and are 90 degrees apart. I'm wondering, at 30 to 38 miles away, can I get a directional antenna to receive them all, or should I opt for omni? Appreciate you sharing your knowledge!

  • Hello, I have a older large antenna on a pole above my roof. It has the 2 terminals to connect an analog antena wire to. My question is, can I use multiple analog to cable connectors to avoid using splitters? Thanks for your time

    • I have a large channel master outdoor antenna. It has the 2 studs with wing nuts to connect antenna leads to. I would like to connect 3 tvs. The question was 3 x 300ohm to 75ohm matching transformers connected direct to wing nuts on the antenna and out to 3 cables to 3 tvs, or one 300ohm to 75 ohm matching transformer to short cable to 3 way splitter/amp as required to 3 cables to 3 tvs. I hope this gives you a better picture. Thank you.

      • I've never done this, so you may want to talk to an installer. I'm assuming the splitter is the way to go, but get a second opinion.

    • OK, so back to my original question. Which is the better way to go, multiple matching transformers, or splitters? I would think multiple matching transformers would be better unless they interfere with each other. Thanks

      • I've never tried it. I'm also having a hard time picturing exactly what you are trying to accomplish.

    • I guess the correct name is a matching transformer. Can I connect more then one to my antenna? Will it still degrade the signal? Thank you again

      • Yes, that's exactly what that is called. Anything you connect between the antenna and tuner will degrade the signal. A matching transformer is usually less than 1 dB loss.

    • I think they may be an older "Twin lead" connector. If it is you need both wires to a coaxial converter.

  • First of all, thank you for taking the time to review and comment on my situation.
    I am looking at a Clearstream 4v for my mother's home. She currently has an older Directv dish with two cables running to it for two TV's. what I am thinking of doing is running a single cable from the antenna down about 3-5' into a splitter and then connecting the current RG6 cables to the splitter that run to the TV's. Those cables are about 35 - 50' runs to the TVs. Am I missing something? Should I consider a booster in place of the splitter?
    Thanks again,
    Ron

  • I just added a splitter and a second TV. Reception at the first TV did not appear to be degraded and the second TV receives pretty much the same channels as the first. However, the second TV is not displaying channels ending in .1 correctly (i.e. 5.1, 7.1, etc.). The picture is split horizontally across the screen (what should be at the top of the screen is in the middle) and somewhat scrambled, audio works fine. My instinct is to blame the TV's tuner. Is it possible this problem could be the splitter or cable run? I am not using any type of amplification.

    • I'm assuming that's the TV. I've never encountered this issue before.

  • You're doing a good job. Do you have a favorable opinion of the Lava HD2605. Do you have any suggestions as to what the best outdoor antennas are most all of the transmitters are in side a fifty mile radius. Most are NW, some Rhode Island stations are SSW. Any input will be greatly appreciated. Thanks.

  • Thanks for a good article! I've purchased an active omni disk antenna by mistake, which need 5V power supply through the coax. My TV doesn't support antenna power. How do I make a simple power supply myself? Is it as simple as to connect the leads to a 5V battery? Don't have time to purchase one! Thanks a lot!

  • I live in Elkton VA and can pick up 17 channels
    Some as far as Richmond,VA but they lose signal at times. What do I need to do to keep them in? I have a Clearstream antenna

  • I have 2 TVs connected to the same antenna (Mohu Sky 60). I can get my NBC on one TV but not the other. Any ideas? Thanks

    • The turner could be noisy. What happens when you connect directly to that TV? If all is wall then, try an amp before the splitter and see if that fixes it.

  • I have a high gain directional antenna to receive station in Dallas about 90 air miles away. Works great on 1 tv and I get 48 perfect channels. If i connect a second tv with a splitter I loose half of the channels. If I try an amplified splitter I loose most of the stations. I love 4 blocks from a very high power fm station so I wonder if it is overloading the amplified splitter and if so is there something like a attenuator just for the fm frequencies?

  • Hi. My TV had lost the channels I checked already the cable and it is connected properly to the splitter and the cables had no defects. My questions are, how do I repair this thing? Is there a possibility that my TV will not receive channels even if it is connected properly to the splitter? Kindly help me. Thank you very much!

    • I would run a direct connection from the antenna to the TV. That will eliminate a lot of guesswork. If the TV is picking up channels on a direct connection then, I'd look at the splitter. If replacing the splitter doesn't work, then try a pre-amp before the splitter.

  • I learned a lot just reading this article. Can't wait to try and get rid of satlite tv.

  • Hi Dennis. I found your website when I was trying to trouble shoot my television reception. I just recently cancelled my cable TV subscription. I'm getting close to retirement and needed to save money. I now have only high speed internet and phone service. One of my TVs has smart capabilities. I reset it to factory settings and was able to get it onto my home network but I cannot get any TV stations. I can access Amazon Prime stations because I am a member. I think that I may need to install an antenna to get other stations, but not sure. What would you recommend that I do next?

  • I have a Lava HD2605 and i'm trying to split it to 2 tv's, when i use a two way splitter I lose signal and the antenna will not move. If I use just one TV it works. I bought a Channel Master Amplifier and the same thing happened I lose signal and power to antenna. Any Idea's?

  • Hi Dennis, I am in an RV. I have 2 TV's connected to a 150 mile directional antenna. I have amps positioned at the back of both TV's. 1 TV on an approximately 20' run works perfectly. The other one on an approximately 50' run works perfectly for about 10 minutes and then the picture and sound go bad. This happens on all channels. What gives?

    • This sounds like an issue with the TV. Have you tried testing it with another?

  • Hi Dennis. First, thanks for taking the time to educate us 'non OTA'ers'
    After reading your articles I've moved forward with cutting the cord! I just need some specific guidance as to what Antenna suits my locations. My goal is to provide OTA stations to 4 HDTV's.
    Here is my TV. Fool Report: http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3de6a43b741cce9c
    With so many types of antennas on the market, I'd like to narrow down the search at least.

    • Since you are splitting the signal you may need a bit of gain. Try the Clearstream 4V. You try using a 4 port splitter. However if the signal is dying grab a distribution amplifier. It will power the signal through the splitter loss.

  • Hi Dennis,
    Thanks so much for all the great information. My husband and I just purchased a house and had a baby, so we are trying to cut down on some expenses, cable TV being the first. I have gotten rid of cable TV and currently just have Verizon internet services. We originally had one TV, but now have have two TVs (one smart TV and one standard TV) and I purchased a Mohu Curve Antenna, which has been working fairly well; however, we would like to connet both TVs and I was wondering what you would suggest. I have read through many of your article and am considering just going with the Mohu Sky, but if we can make it work with just the curve, that would be great. Here is my TV Fool report: http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3de6a480f21ea8f2
    Thank you!

    • The curve should work, but the newer Mohu Glide should be a bit better. make sure you put the amplifier between the amplifier and the splitter.

    • Excellent, I hooked everything without it today and get about 33 channels on 5 tvs, however a couple do get pixilated at times. I will order this and run each tv from it to hopefully eliminate the pixilating. Thank you for your help.

  • Hi,
    I am currently using a Mohu Leaf 30 mile range indoor antenna. I can pick up ABC and FOX just fine because they are both within 5 miles of my new apartment. However, NBC and CBS I can't pick up right now, but they are within 17 miles (also a slightly different direction than ABC and FOX). I have a feeling it is due to some of the larger apartment buildings in between the NBC and CBS towers and my apartment. When I was living in an area with no large buildings near me, I could pick up all 4 major stations, even when ABC and FOX were about 15 miles away using the same Mohu Leaf antenna.

    So my question is, will trying a stronger attic antenna like the Mohu Sky 60 give me a better chance at picking up NBC or CBS because it has a longer range? Or is it the case where if you have a 30 mile antenna, and you can't pick up stations broadcasting well within that mileage due to obstructions, then a 60 mile antenna isn't going to be any better? I'm willing to give it a try if there is a chance on getting 2 more major stations (as long as I can return it), but just want your input if it may just be a waste of time and possibly return shipping fees.

    Thanks

  • Hi, I am trying to connect an outdoor antenna at my mother in laws. When I connect the antenna directly to the main coaxial I get several channels. However, I have to unhook her internet to accomplish this. When I try to run a splitter outdoors so the antenna gets signal as well as internet, I get no channels. I am not an expert, but thought this would work. Any suggestions?

    • The Antenna should be on it's own dedicated line. The Internet service is completely separate.

  • I have a Clear Stream attic antenna which will be feed into a pre-amplifier and then into a 4 way distribution amplifier in an outdoor junction box. My question which I fail to get a clear answer is this: Do I need to ground the antenna as well as the distribution amplifier?

    Thank you

  • I hooked up a lava antenna to my tv. I have the new 50'wire attached to the antenna which sits about 20 feet in the air and that wasn't long enough so I have it attached to the existing wire which is about 40 ft long I'm not getting a signal at all on the TV am I using too much cable in my hookup?

    • I get enough coaxial to connect it directly to the TV. That's the best way to see which channels you can actually receive.

  • Thanks so much for publishing this site. Very informative. Here is my question: Does connecting a second distribution amplifier after a long coax run add any strength to the signal? I get great reception on my first tv which is centrally located and is about 80 foot coax run from 30 foot hi roof mounted long range directional antenna to first dist amplifier. However, signal is then spotty on remaining tvs which are daisy-chained from first dist amplifier on additional dist amplifiers which take coax to opposite ends of the house. Weather seems to affect reception on other tvs as well. All coax is 6g which was installed by DirecTV about 10 yrs ago before I cut the cord. What do you recommend to get better reception on the other tvs? BTW I receive a few channels on my first tv which aren't listed anywhere on my tvfool report but that isn't the reason for my inquiry.

    http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3d60edc88ad60657

    • I would re-run the cabling. It's possible that the technician didn't to an optimal install for TV reception. That said, your signals are fairly weak. I would consult a local professional to get the most out of your situation.

  • Thanks for this site and info.

    I am looking to get an outdoor antenna and run it to 2 TV's. I plan on getting a HD DVR for each as well (if that makes any difference). But here is my tvfool report and I was wondering what is the best outdoor antennas (please give me the top 2-3 you think are the best so I can research them) for my situation. When I split them I am going to run about 25 feet to 1 receiver and then about 70 feet to the other receiver. So I need that "distribution amplifier" as well? I am new to this so any info you can provide would be greatly appreciated.

    http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3d60ed5d767f3268

    thanks in advance!!!!

    • The antennas in this guide on TV antennas are what I typically recommend. The distribution amp is a good idea, but just install it to one without a splitter first to get an idea of what you can receive.

  • Great info, thank you! I need to hook up 2 tv's. My channels are in about a 180 degree arc, so I was thinking of using the Winegard HD8200U Platinum Series. My run to my first TV is no more than 30 feet. Where the drop comes thru the wall is where I would slit. To the second TV is about a 50' -55' run. Am I on the right track? The antenna will be mounted at the peak of my roof. Peak to ground is about 28'. How hi above the roof line should I be?

    • Sounds like you got it. Your roof sounds like it's high enough for good reception.

  • I have 5 tv's currently hooked up to DTV. I want to cut the chord and for the 4 out of 5 TV's I just want to see local channels. The main TV I will stream using firestick/hulu ect...! My question... is it possible to use the existing dtv cabling/splitter to hook up a digital antenna (recommendation for antenna I am about 50 miles max out from towers living in Slidell, Louisiana suburb of New Orleans) and get regular stations. My thought was to remove satellite dish and install digital antenna in its place....What you think...?? Thanks for your response..!!

  • Hi I have two tv's don't have any cable or internet only a smartphone and I would like to watch channels like TBN and Daystar is it possible to do without having to get internet or a cable company setup? If so how? Thank you

    • I would check to see if there is a Daystar app. I’d be shocked if they didn’t have a live stream. Also, TBN is on broadcast in certain areas of the country. See if they are available using an antenna in your area.

  • Great article. I've got an outdoor antenna running to a 2-way splitter. When we first connected, every single channel on both TVs was strong. After coiling some extra co-axial length and connecting ground wire, there is a single problem channel - it comes in excellently on one tv and hardly picks up on the other. Any suggestions?

    • Try and put a pre-amp before the splitter. The splitter and length of coaxial will add some attenuation. The pre-amp is a way to compensate for that.

  • Hi, excellent website, I wish I founded this a month ago. I bought an RCA ANT705Z attic/outdoor antenna. It seems to get all of the channels that I want except for one, but I think I can work through that issue. I want to hook up to my pre-wired home (by direct tv) with coaxial cable‘s, but I have five TVs that I need to hook up. I read your articles on balancing the splitter, but I did not find a five or six way powered splitter.
    Can you offer advice on a splitter For my situation? I assume it needs to be powered.
    My plan is to start with the powered splitter, then add a preamp if necessary. The run will be less than 50 feet to the splitter. Let me know if I’m off base.

  • I have a seebest sb-7530MZ1 trunk distribution signal amplifier with 2 output. I connected 1 4-way splitter 1 foot away after my seebest trunk amplifier on each output to connect to my 8 tv. Distance of my coaxial cable line after the 2 4-way splitter going to my 8 TVs are about 5 to 15 meters. Now, some of my TVs are having good reception but some channels are not clear and some TVs totally having snowy reception. Im planning to change my 2 4-way cheap splitters to a 2 4-way indoor signal booster. Will these improve my TV reception?

    • The best thing to do is to not split the signal more than you need. If you are getting the signal to 8 TVs it's best to go with an 8-way distribution amp. This will balance the signal to all 8 TVs while boosting each port. Also be aware that if you are using different model TVs, that some TV tuners are noisier than others.

  • I have seven TV's throughout our house. Currently I'm paying my local cable company $230 a month. What would be the most efficient way to hook all seven TV's to a over the air antenna or will I need multipal antennas in order to do this. I'm almost sure putting to many splitters inline will decrese my signal. What's your suggestions? Thanks

    • If you have strong signals, a good 8 port distribution amplifier would suffice.

  • It's technically possible, but I've seen some sloppy cable installation. Every time a splitter is used the antenna signal is split whether the the port it being used or not. Also if they didn't split the lines optimally you can have one line be much weaker than others. Basically my advice is to give it a try. It may work, but if it doesn't work it still may be possible for you to get reception if you fix or reinstall the coaxial cable.

  • Also, if you are going with an amp. I would get a 4 port distribution amp and then rewire all the cables to go to that one distribution amp. That would be the optimal solution.

  • What's up Dennis... I just ditched my AT&T U-verse bundle, but after a little negotiating I was able to keep my internet at the introductory rate of 50 mbps for $40 for 1 year although I'm not a new customer. I subscribed to Directv Now and have 3 tv's that I will be using. I'm trying to choose the best OTA tv antenna(preferably indoor) for my needs. I used the channel locator tool from Mohu and was considering the Leaf 50 or Curve 50 which has 40 channels and the Leaf Glide which has 48 channels. I'm going to provide you with my signal report from TV Fool hoping that you can help a novice like me make an informed decision on antenna and any other accessories that I might need. Thanks in advance... http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3d60ed8f1313667b

    • Hi Joe, thanks for stopping by. The Mohu Glide may work. However, there are a couple channels in the VHF range. Specifically NBC 5 could cause issues. However, I'm betting they have a UHF channel that isn't showing up for some reason. Check their website and see if they have a version of their broadcast on a channel above 13. If they do, the Glide should be fine. Otherwise, you may want to look at something like the ClearStream 2V. Check our Guide on TV Antennas for more information.

      • I appreciate your advice. I will look at Ch 5's website today. The reason I didn't want to install an outside antenna is because I'm renting and don't know how much longer I will be staying here.

  • Hi, I had an antenna installed and it works fine for the main tv but the one in my bedroom automatically shuts off in 10 minutes. It's a new flat screen; what's up with that?

    • If it literally turns off, I would call the support of the TV manufacturer. It seems like there is an issues.

  • Been a cable cutter for a few years now. Has anyone tried to combine the signals from two antenna's to improve better cover more area? How would one combine the signals at the set? I have an outdoor directional that is pointed one way and am thinking about a Mohu sky as a second omnidirectional to pick up a few more stations in different directions. I have stations in 3 main directions and all are 50-65 miles away. We often lose certain stations due to weather, but also partly because the broadcast power of those stations are also low in the direction the antenna is pointed. In other directions, those same stations have more broadcast power and come in fine, but only if the antenna is pointed that way.

    • You can do it with a band filter. For instance, one antenna is optimized for VHF and the other UHF. Each antenna is joined through a filter that filters out the sub-optimal band for each.

  • Need help with a Mohu Sky Sixty. Have not installed yet. I was told that I would need a 3 ghz passive splitter to connect to my 7 TVs. I cannot find such a beast that offers more than two ports. Am I misunderstanding something? My runs from the splitter will be 12, 20, 30, 45, 75, 80 and 90ft. Would I be better off using two of the antennas to cut down on the longer runs of coax?

    • How many TV's are you installing? There isn't a reason to get a 3Ghz splitter. the highest TV frequency is under 1 Ghz.

      • I have runs for 7. I was planning on using a PCT amplified 8 port splitter. However, after reading over your information I am concerned that it would overpower the signal going to the shorter runs of coax. Should I split off the shortest run before the amplifier splitter or just add some coiled up coax to the shorter runs to reduce the signal strength if I discover I have too much power going to them?

        • Check the highest noise margin. If it's under 60 then a couple of dB boost from the distribution amp should matter that much. You can check the noise margin using the signal report from TVFool.com

  • Different setup here. TV fool shows I'm 38.7 mile distance. Have 2 indoor leaf style antennas, 1 with an amplifier. Have a Linear 2512 ChannelPlus DC & IR Passing 2-Way Splitter/Combiner. Can I connect the amp directly to the TV then to the splitter/combiner which then will connect to each indoor antennas? or 1 antenna gets the amp while the other doesn't the connect to splitter/combiner then to TV.. I can get 2,4,5 channel when placed at a certain spot then 7,11,13 at another spot which is why I figure buy 2 antennas that go to 1 TV. Both antennas will be 8 feet away from TV

      • It kind of works. Listing only channels I watch but more channels are picked up. Antenna w/ amp gets 2,4,5,7&30. 2nd antenna (no amp) 7,9,11&13. Unfortunately, 11&13 doesn't show picture. Being 38.7 miles away, it needs an amp. Thanks for your guide, I learned a few things!

  • Hi,
    I have omnidirectional antenna with Channel Master pre-amp and passive splitter to my two TVs. Everything works ok if only one TV is ON but when both TVs are on then one or two weaker channels are either not available at all or signal drops frequently. Is there any way to fix it?

    Thanks,
    Kris

    • It's possible that the tuner is adding on both TV's is adding too much noise. You could try an amplifier before the splitter, that may overcome the noise generated by the tuner. This is just a suggestion, it's hard to know exactly what is wrong without troubleshooting the setup.

  • Hello,
    We just installed the Mohu Sky 60 yesterday. So far to one TV only. Last night we received 18 channels but this morning only 5-PBS stations. It’s snowing in Montana. Could that really affect reception that much? On TV Fool all local channels were shown in the green. Thanks

  • I have a powered winegard antenna that uses a power inserter. If I get a powered distribution amp, will that replace the inserter that came with the antenna?

    • I would contact winegard and get their take on it. I haven't worked with their power inserter and don't want to give you bad advice.

  • Hi Dennis,
    my name is Jim and I live in Central Florida (Palm Bay looking towards
    Orlando Towers). I am looking for a little guidance on my cutting the cord to
    OTA setup I am currently building; I was hoping you might be able to help. I appreciate
    any and all feedback.

    In short I
    am looking to get ABC, CBS, NBC and FOX on four TVs with (running from the
    antenna) two of them running a distance about 76’ and 80’ while the other two
    running a distance of around 46’ .

    From the splitter
    the TVs will be about 45’ away, 57’, away and 16’ away x2.

    http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3d90381e6511b4db

    BACKGROUND

    I currently
    have this directional antenna (below) setup inside my attic, around 14’ -15’ up
    high. When I first set it up and auto tuned the antenna in, facing North West,
    I got 3 out of 4, ABC, CBS and NBC. Then I moved it around for days hoping to
    get the proper direction for FOX. That didn’t work and I lost NBC also. Currently
    I am getting 45 channels, I have gotten a little more but I had fidgeted around
    too much.

    PROBLEM

    So, I now
    get 2 of the 4, ABC and CBS. Both come in fine. I plugged in my address into
    Antennas Direct (AD) tool and its mapping guide showed that all the towers are
    UHF except for the one tower for NBC, it is VHF. My current testing phase is
    setup very mundane. Though I hope to be able to expand a little on the
    equipment and pick up NBC, channel 2.1 and FOX, channel 35 or 35.1 (It is in
    the 35’s), though I do not want to spend a bunch of cash at the same time.

    ***** Antenna > the rotor box (the amp too I believe
    is in the box) in my garage > main tv in the living room *****

    SOLUTION

    So here is
    what I think my setup should look like (running all new RG6) :

    Short Version

    Antennas’ x2
    > Combiner > preamp > coax to outside cable box > Surge protector
    > coax back into the attic > distribution splitter > to 4 tvs

    Long Version

    Antennas’ x2
    > Combiner > preamp / (all in the attic near the antennas) / coax to
    outside cable box > Surge protector (and grounded using the same green ground
    wire as Spectrum Cable that is attached to the grounding rod in the soil) > coax
    back into the attic > preamp splitter > to 4 tvs

    ANTENNAS

    After doing
    all the research, the 8 Elemental Bowtie Indoor/Outdoor 70 Mile Range sounds
    pretty good and it has great reviews too. It is multidirectional and AD also states
    that the DB8e Bowtie has 17.4 dBi gain (Is this actual Antenna Gain or just
    marketing hype?) I figured I could combine both antennas with a USVJ/Combiner. I
    plan on testing the antennas separately then conjoined, more about the combiner
    in the next section. I might just use the DB8e due to it being 70+ miles and a
    multidirectional ( the Moho Sky 60 I had seen you use appears to be in the
    fringe zone of the towers distance I am trying to use fom my home). Question 1), With my current antenna,
    do you think the DB8e is a fair choice, or is it down right terrible? Question 2) Below is additional options
    for VHF pickup also, the cheaper VHF kit sounds like a good addition to add
    onto the DB8e. But I am not entirely sure.

    Also, I
    called them directly and we went over my location/tower mapping. The lady had
    suggested I need to get two expensive antennas, the DB8e + the Clearstream 5
    (on their website too) together with a combiner for inside the attic.

    https://www.amazon.com/Element-Bowtie-Indoor-Outdoor-Antenna/dp/B00C4XVOOC/ref=sr_1_1?ie=UTF8&qid=1522136977&sr=8-1&keywords=db8e+antenna

    I read that
    most basic VHF antennas work just as good as the expensive ones (I may have
    read this on your site), after I saw the prices for both of them above, I
    looked around more and saw this VHF Retro Fit Kit from the same company, $28 on
    Amazon and $20 from AD’s website.

    COMBINER

    So I have
    been researching combiners and I understand that most, if not all are split
    with one side UHF only and the other side VHF only. With the UHF side dropping
    the VHF signal from the antenna attached on that specific side, and the VHF
    port side accepts the VHF while dropping the UHF signal from the attached antenna.
    Also, using a combiner can increase the signal you are trying to get with the
    second antenna, let’s say VHF, like in my case, but it drops the UHF signal
    over all from using the combiner. So, I may pick up the VHF signal increase that
    I am seeking but I may also suffer a fair bit of UHF bds, though usually not
    enough to discourage buying the 2 antennas and the combiner.

    QUESTION 3) Are there combiners that could
    handle both UHF/VHF on one side and UHF/VHF on the other side? Meaning, will I
    get the best from both without loss, or will I suffer significant loss?

    I found this
    question and answer (below) on amazon when looking around for more information
    and it left me a little confused.

    #### Question:
    Can you combine two (2) full-range (VHF+UHF) antennas with this device? ####

    #### Answer:
    IF what you are asking for is combine two signals that already carry UHF/VHF
    into one feed, I used a Wineguard CC-7870 (
    http://www.amazon.com/Winegard-CC-7870-Antenna-Coupler/dp/B001TK3C82 ) to
    combine two Clearstream C2V ( http://www.amazon.com/gp/product/B007RH5GZI/ )
    antennas pointed at different broadcast locations. Keep the cables near equal
    length for best results. see less

    PREAMP/Distribution Amplifier

    From what I
    understand, if you’re close to towers, you don’t need a preamp. If you are far,
    you may need a preamp. Your distance and signal strength are key here. For the
    two channels I am hoping to pick up/back up, and that they are 51 and 52 miles
    away I believe a preamp is helpful here. I have read good stuff about the Winegard
    LNA 200.

    I liked your
    article on “Which Splitter to Use”, and I am going with the PCT 4 Port Cable
    TV/HDTV/Digital Amplifier. Thanks for sharing knowledge.

    I also found
    this webpage below with a decent guide of what I might need to do concerning Preamps
    and Distribution Amplifiers, while taking distance and number of splits into
    account. This is why I think I may need both.

    Thanks for
    reading this lengthy post and all of my questions and once again I appreciate
    any and all feedback.

    Have a good
    day Dennis.

    • I would love to help you out, but I'm really busy at the moment. Is their any way you can condense you question?

  • My tvfool map shows mostly north and south tv towers (both VHF and UHF). Both directions are important. The easy answer is an omnidirectional antenna. Two directional antennas pointing in opposite directions seem hard to configure due to signal interference between the two. Any other type of antenna you would recommend?
    Great site! Thanks!

  • Dennis, there's a wealth of information on your site. Thank you. I'm interested in one situation that I couldn't find though. I want to install a second TV and deliver the signal wirelessly. I'd like to avoid running new cable for the obvious reasons and to use the TV in more than one location. Do you have any recommendations for a WiFi transmitter of OTA TV signals?

  • Thanks Dennis. If I understand the product correctly, I think I'll try the Tablo Dual Lite DVR. I have an available USB HD and a Roku Stick so if this works well, I just need another Roku Stick for the 2nd TV or a smart TV with the Tablo app. Cheers!

  • I'm using a Comcast 8 pole amp for over the air. Is there too much amping that can burn out a tuner on the TV? The cable from the comcast box, I cut cable tv, to the back of the house. It feeds into the comcast amp and is distributed to all rooms. Everything works well but my 47" Vizio's tuner no longer receives oTA. Troubleshooted and it is the TV's tuner. I think it burned out.

    • To much amp doesn't "destroy" the turner. It just overloads it so it cant get the signal. The tuner should still work. Test it by connecting it directly to an antenna.

  • Thanks Dennis,
    It's the tuner on the Tv that went bad. Bummer... I can only stream with Direct Now.

  • Are there any services in the Atlanta are that will install outdoor antennas? Currently have an indoor antenna in my attic but feel I could get better reception if it was up higher.

  • We want to install a digital/he antennas but we will have 4 HD tv's hooked up to it. They will not be run all at the same time but about twice a year and mostly at night.what should we get?

  • Question: is there a way to wirelessly send a signal from my roof mounted antenna to my tv?

    • There are a few technologies that do that, but none that I really call reliable so far. Many companies are working on it.

  • Thank you Dennis for a very helpful article.
    I'd appreciate your additional advice.
    My plan is for an eave mounted antenna, something like an RCA ANT751Z, (towers are 49 miles away). I can keep the run from antenna to splitter to 50' or less.
    Since I'll be needing a 4-way splitter anyway, wouldn't it make sense to get an amplified splitter, and try it unplugged?
    Also, no basements here in FL. Adding an outlet for an amplified splitter in the attic will keep it cleaner on the living room wall, but attic install makes it a PITA for servicing when/if needed.
    Lastly, what do you think about grounding an outdoor antenna? I don't see much mention of that in manufacturer's guides, but seems important. I don't know whether local codes require it.
