How to Connect Multiple TV’s to your OTA Antenna

Cable TV Alternatives: Splitters & Amplifiers


First of all congratulations. If you are reading this post you are ahead of the masses, and have realized OTA (Over-the-Air) TV is an amazing alternative to Cable TV. Now you are looking for a way to push your free HD TV signal to multiple TVs in your house.


Coaxial Splitter

The first thing you need to do is buy a coaxial splitter. This is an inexpensive device that will split your OTA signal into multiple sub-signals, allowing you to push free TV broadcasting to multiple TVs. It’s my understanding that splitting the signal in two results is a 50% drop in signal strength (3.5db). And every additional split will continue to decrease the overall signals strength. So if you have a weak or marginal signal coming into the house from the antenna, splitting it will have a negative effect. This also means that if you only need a two-way splitter, don’t use a 4-way splitter because you’re losing more signal strength with every unused output. Finally the more distance the signal has to travel, the weaker the signal becomes. So less feet in coaxial cable, means stronger signal, equating to better picture quality.

But don’t get ahead of yourself; you don’t know if splitting the signal will cause problem until you test it. Once you have your splitter installed, connect two TVs at a time. Then test the signal on both TVs. If successful go ahead and connect three TVs. And again, test the signal. If any point during these steps you notice that you have lost signal strength, it is time look into buying an amplifier.

Side Note: Be careful with 3 way splitters. Signal loss can vary substantially across the three outputs. Meaning if used, two TVs could work fine, while the third would suffer from a weaker signal. I did some research and found an example of a Splitter that addresses this issue: the Monster Standard RF Splitter. Click here to read the reviews: “If you are looking for a 3-way splitter with equal signal loss on all 3 outputs, for $12 this is a good value.”

Coaxial Amplifier

I don’t suggest starting out with an amplifier because some antennas come with built in amplifiers that can easily support multiple TVs. The Sky from Mohu for example, is small, powerful outdoor antenna that can provide uncompressed HD broadcast to multiple televisions in a home. (also has a rang of 60 miles by the way)

When buying an amplifier you need to understand that there are two basic types. A PRE amplifier amplifies the signal received by the antenna into the down cable. It should not be anywhere but on the original antenna cable right at the antenna. A DISTRIBUTION amplifier allows you to redistribute that signal through multiple outputs, while maintaining the same signal strength.  Click here to read Amazon reviews on the Channel Master 3414 4 Outputs Distribution Amplifier.

    Laura, I haven’t had the time to try it yet. Sorry.

  • Yamz

    Good day, I wonder if I only need a splitter and a cable wire to connect multiple TVs to the set top box os is it one box for one TV or splitter and cable wire will do? please help… thanks!

  • laura

    Did this work? And how did you connect the antenna into the current coax lines? I’m in the same boat in Nashville. Looking to get rid of Comcast cable but unfortunately have to keep their Internet till Google is up and running hopefully in the next year or so….

    That should work fine. Please check back in if that does not work and we can try to troubleshoot the issue.

    Currently both Comcast cable TV and internet come into the coax cabling in my home. I want to get rid of the cable TV and keep the internet. Can I hook my home’s coax cabling up to a new amplified antenna while still keeping the internet service through the cabling? Or will the antenna and internet signals interfere with each other?

  • KilltheCableBill

    Hi Beck – Yes, you can absolutely use a separate Antenna for each TV.

  • Beck

    Can I use a chromecast/laptop and MUHU antenna on each TV instead of splitting the signals?

  • KilltheCableBill

    Hi Donna – Yes absolutely. But keep in mind that your number one priority is to find a spot that can reap a quality HD signal. Once you have found the right spot – then think about how best to run the coaxial cable. If there one in the same – then your job is easy.

    Is it possible to hook sky antenna up to the outside where your existing cable was that has the coaxial cable already in place to existing tvs?
