Here is a question for anyone who can answer(or anyone with some real training). when i use an aerial drop through a diplexar to get the antenna for a dual tuner reciever into the room with the second tv(in cases where the distance between tv2 and the reciever is to great for the remote to function properly) i get a grainy picture no matter which modulator setting i choose. If i take the aerial drop out, the picture is perfect. it has worked for me in the past with ok results but the last 2 ive tried came out poor. any ideas of what would be causing this? do i need a specific type of splitter to combine and seperate my antenna and tv signals? is it differant on each reciever? are there too many bands stacked here for a single wire? thanks for any help-
