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.

  1. I have 4 tvs that are currently run off two cable boxes and through a 4×4 HDMI Switch/Splitter. I am ready to cancel cable, but as I already have the house wired with HDMI and coax in not near the tv locations, I was considering the following set up.

    OTA amplified antenna (Trek Omni Directional)
    via coax to
    Digital Converter Box (Iview 3500STBII)
    via HDMI to
    4×4 HDMI Switch (Monoprice)
    via HDMI to each TV

    Any thoughts on if this would work?

  2. Trying to figure out the best way to tackle this job. I have 5 tv’s currently through direct tv. Looking to get rid of it and get an HD antenna for locals. I’ve read about the mohu leaf antenna, but not sure if I need one of these for each tv or if I need a roof antenna. I know without a doubt I’ll need an amplifier to have good signal strength. I should also be able to use the existing house coax wiring as well I assume. Just not sure the best way to have all 5 tv’s up and running. I have netflix currently and would like that on each, and I’ve also looked at the sling which I think would be good for getting the channels I want to each.

  3. Hi Nasser – Honestly i don’t know if you can get a strong enough signal using one antenna. I suspect you would need multiple antennas for something like this.

  4. I apologize for my delayed response. What I ended up doing, is I got a box that will accept my OTA signal. I connected that box to my receiver, and now I can view through my receiver. also, the box I got allows me to record.
