I'm considering purchasing a AM21 to add a few local OTA subchannels to my system. I have a Slimline dish with the 3 LNB feeding a HR44 receiver with 2 Genie mini receivers.
My outdoor antenna is on the house next to the dish. Is it possible to feed the OTA signal through the same coax that comes from the LNB into the house, and then split the signal at the HR44 so that the satellite signal goes into the HR44 and the OTA signal goes into the AM21?
The home was wired with coax when it was built and all the drops terminate to an outside box. I originally had the OTA antenna connected to this junction box to the living room, but once I got Direct TV the installer used that connection to get the satellite signal to the living room. I'm trying to find a way to not make another coax run to the living room because the living room jack is on an exterior wall where there's not enough room in the attic to make a new drop down the wall.
