I installed an OTA antenna to go with a 222 with an OTA module. Outside I have it diplexed. What I cant figure out is how to diplex in the mechanical room to get the OTA signal to the 222 in the living room, and the backfeed to the bedroom. I've tried a couple different configurations with diplexers and splitters in the mechanical and can't get both signals at the same time. If I get the OTA signal to the 222, it kills the picture quality on TV2. If I get a clean TV2 picture, it kills the OTA signal. Any thoughts?
