I'm getting poor/non-existent UHF remote reception from our VIP622 in other rooms of our new house. I didn't have this much problem in our old house, but for whatever reason our new house blocks all signals. I read that I can move the remote antenna into the room with the TV by using some combination of spitters and/or diplexers. I tried using a plain spitter at each end (2 lines from the receiver for the remote antenna and TV2 coming into the spitter merging into a single coax...and then being split in the other room with another spitter installed in reverse to the TV and remote antenna). This fixed the remote reception problem but significantly degraded the picture quality. Should I be using a diplexer on each end or some combination of splitter and diplexer? If I need a diplexer, is that something Lowes would carry?
