I have a ground loop in my system that's being caused by the coax cable running from the dish to my Direct Tivo. If I unplug both coax runs (dual tuner) the buzz goes away, does anyone have any suggestions on how to eliminate the hum? I had a ground loop when I used to have cable and I used a ground loop isolator but I keep reading with satellite you shouldn't run anything inline between the dish and receiver. Any suggestions?
