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?

Hi countryboy, I eliminated my ground loop buz by running a ground wire (from radioshack)from my direct tv dish to my outside house electrical ground wire (usually near your elect. meter).
good luck - Rob

Yep, me too. attack the loop at the source first if you can.

Okay I don't really about things like this but is there a specific place on the dish to attach a ground wire? Also I will look in the next couple of days but is your house electrical ground wire an exposed wire?
