Combiner

Okay, I ran 50 feet of RG6 so I now have two sets as TV2. I did have to add a 10 dB amplifier to clean up the signal a bit. The TV3 has a single coaxial input and I am using an A/B switch to select between the OTA antenna and the DISH. Could I use some sort of combiner rather than an A/B switch?

Yes, you should be able to do that, as long as the combiner can support the entire frequency range.
At the risk of posting something you may already know, try any coax splitter you have around the house, but connected backwards. Antenna to Output 1, Amplified signal to Output 1, and TV3 connector to the Input of the splitter. It is also possible to do that combine before the amp if the antenna signal is present there too.,

I have the same situation as the original poster and have put a "splitter" in reverse to combine the output from the receiver and the output of the antenna. The problem that I have is that the OTA signal after combining is very week compared to the signal coming from the receiver.

Is this due to my splitter being used as a combiner? Perhaps I need to amplify my antenna signal???:confused:

A Splitter (combiner) reduces the signal about half. If the antenna signal coming in hasn't already been split and added coax runs, it is less likely to need amplification. A 4 way splitter would reduce it twice as much as a 2 way.

The 622 home distribution connection has some amplification to start with so it may be stronger than the OTA signal (depends on how the antenna signal gets to the combiner).

Pretty much, anything you connect to the coax will reduce the signal some.
I bought a combiner/splitter from Radio Shack and did what you're talking about. I've tried regular splitters, and they don't work for what we need.

Thanks Harry for the info. I will make a stop there tomorrow.

This worked for us as well. We used to link 2 UHF ants, on epointing towards Fresno for their OTA and one towards Sacramento for those. Worked great.
I am using the Rat Shack combiner/splitter as well and it works great for me.

I tried a monster brand splitter I had laying around first and it didn't work for me, that was when I went and bought the rat shack one.
