I just purchased a RadioShack Diplexer (Sat/TV Splitter/Combiner) Part # 16-2567 (40-2150MHz) It is supposed to combine a sat feed and ant feed to one coaxial cable. I have a Dish Network 522 receiver in my living room and I have the home distribution cable from the back of the receiver going to my bedroom. I installed the diplexer on the sat feed from the living room receiver in the sat side of the diplexer and a pair of rabbit ears on the ant side. Ant. works perfect have great hdtv signal coming in. However when I tune to channel 60 (my sat feed channel) it is really fuzzy. Do I not have the right kind diplexer?
