Can you connect two antennas to one tv with a cable splitter?

Question

I have a cable splitter connecting two cables from my antenna to the tv (just because I needed the length of two cables). I was wondering if I could put another antenna on it via the splitter to get more channels possibly?

Answer 1

It's a bad idea. Feeding two similar (same frequency band) antennas into any type of combiner invites multipath distortion plus capacitive interaction between the two. You're more likely to wind up with less signal strength than you have when using either one alone.



The way to get more channels is a better single antenna, and maybe a rotor. If you're using an indoor antenna, get a full size one above the roof or at least in the attic if you can. If your antenna is fixed (non-moving), and your TV stations are in different directions from your home, consider a rotor if you have a full size antenna above the roof.

Tv Antenna Splitter

Answer 3

Tv Antenna Combiner

Answer 4

A splitter or diplexer will combine the input from another antenna pointing in a different direction. There will be some signal loss due to the insertion of the splitter. You may have the problem of multipath distortion which in the analog days only caused ghosting but really messes up a digital signal.

Yes, you need a "antenna combiner" with the correct type of connectors. For example combiners use 75 ohm F connectors or 300 ohm screw terminal connectors. Older antennas may have feed lines that are the screw terminal connectors. These are pretty common and are available with both types of connectors in one combiner. I believe you can still get them at Radio Shack and at most hardware stores. Note: Using a combiner works best when one antenna is only for VHF TV and the other only for UHF TV. If you combine two antennas that either or both are VHF and UHF capable you will encounter a problem with multipath reception. Reception can be badly degraded. FYI. According to reports the government will eventually end all terrestrial TV broadcasting. When they do get around to doing it, both antennas will be useless. Since antennas are going to be obsolete antenna prices should be dropping. It might be beneficial to just get a new VHF/UHF antenna and get improved reception of the channels you already have for the time we have left. You might consider moving the indoor antenna outside and put the combiner with them and use one good cable to feed your TV. Leave the antenna amplifier inside. If you have a rabbit ears (or similar) antenna inside it won't last long outdoors.

Answer 6

You can't connect 2 antennas at the same time unless they are a matching pair designed to run together. Anything else will not work.

Answer 7

They would need to be exactly the same as each other on the correct mount at the correct distance from each other using the same down lead. This would come as a package and would need to be erected proffesionaly.

Answer 8

you would need a combiner . probably a proffesional job. though its easy to install a VHF /UHF combiner yourself If youjust want to combine a VHF and UHF antenna.
