I am not sure if this is the right forum for this, so please forgive me if I am wrong.
I have a dish 722 rx and it has a rf out (tv2) that is set for channel 60. My wife wants to put that on the home OTA distribution amp. How do I "blend" that signal with the OTA antenna so that channel can be seen on the rest of the tv sets in the house (I know that the sets will have to see the same content if that channel 60 is selected).
You should be able to combine the TV2 out with the antenna using a splitter in reverse. In the 722 menu, press 6, 1, 5 to get to the modulator set up and change the TV2 output channel to a channel that isn't nearby any channels from the antenna. The last time I tested the TV2 out from a 722 I think it was around 16dBmV so you shouldn't need an amp unless you're splitting much more than a 2-way and 8-way. There should be a little device called a Diplexer at your home run. There should be a port labeled VHF/UHF or ANT or maybe TV, that is the one that gets combined with the antenna.
