How to Split an Over The Air Antenna Signal to Multiple TV’s

How can I share one over the air antenna to multiple TV’s? I will show you how in this article. In most cases, your home may have existing coaxial cable wiring already setup in the house. If you had some type of cable or dish television previously installed, you likely have most of the wiring done for you. The great part about using an over the air antenna is, you can tap into the existing wiring to plug in your HD antenna. From there you can install a splitter to distribute the signal to several televisions. If your house does not have the existing wiring you will need to run the cabling yourself. I will show you how to do that as well.

Splitter Placement

Once you have your antenna installed and if your house is fully wired, all of the coaxial cables will come to a central point. In most houses, it is in the basement or utility room. It is a bundle of black cables. It may be helpful to first identify where each cable leads to. Once you have this figured out, label each cable with a piece of tape. For example, a label may read “Bedroom 1” or “Living Room”. They may have already been labeled by the electrician. The cables could already be plugged into some type of splitter from your cable provider.

Main Coaxial Cable Stack

Passive or Powered Splitter

Most of the splitters that the cable companies provide are passive and are not powered splitters. You may be better off replacing it with a powered splitter if your second TV is more then 150 feet away. This will allow you to boost your antenna signal further. If your second television is far away in another bedroom, the powered splitter will boost the signal for better reception. Make sure not to use the splitter for your internet router/modem. Your antenna should be separate from this signal and not combined.

Using Existing Wall Jacks

Pictured above: My cable from the HD antenna in the attic is plugged into the closest wall jack that connects to the splitter in the basement.

Attic OTA Antenna

Depending on where you’re over the air antenna is placed, you can use the closest wall jack to plug your antenna into. My antenna is in my attic, so I plugged the antenna cable into the closest wall jack in the upstairs bedroom. The cable then runs from this wall jack to the basement to the central stack of cables. This now becomes my antenna input cable. Then I placed my splitter/distribution amp in this area. Next, I plugged in the coaxial cable from the antenna wall jack into the input of the splitter. Then I identified which cables in the bundle lead to the wall jacks where the TV’s are located. I plugged each TV cable into the outputs of the splitter. Again, if you do not have wall jacks installed, you will have to run new coaxial cable to each television and central location. You will also need to provide power to the splitter and in some cases to your antenna. For certain setups, a passive splitter (unpowered) will work if your cable runs are short and your antenna booster is powerful enough.

Adjustable Gain Amplifier

Channel Master CM-7777HD TV Antenna Amplifier with Adjustable Gain

cm-7777hd-2t

I have been getting a few comments from people saying that a powered splitter is causing a signal loss due to overmodulation. Most powered splitters give you all or nothing signal amplification. You have no control over the gain of the outputs. The Channel Master CM-7777HD TV Antenna Amplifier can alleviate this problem. It allows you to adjust your output gain. This can be handy if you only need a little gain on your other TVs. This device will work well with a passive splitter. Just place the Channel Master CM-7777HD TV Antenna Amplifier between your OTA antenna and your passive splitter. Then dial in your gain. This can give you much more flexibility in your splitter setup.
