Have Dishnetwork on my 2011, 3670. Have the receiver hooked up in living room. Back fed thru cable jack to get satellite in bedroom. That works great. Tried TV in basement and that jack picks up the satellite but very snowy and sporadic. Finally ran wire thru window from Bedroom to basement to watch LSU win the SEC tournament. Any clue what to do. Is there a wiring diagram for the cables? Thanks in advance for your replies. Steve A. Dagro
