Cutting Edge: ECHELON '07
My dish isn't grounded but my coax is. 4 coax from the dish go into my basement into my grounding blocks which are grounded to the main house ground. Then small 4 foot loops to the multiswitch and then from there to the receivers. I had it all grounded before. When my installer came to swap the dish the only thing he was concerned about was making sure the coax was grounded. But then my dish is on a 5 foot metal pole which goes 2 feet into the ground into cement so perhaps that grounded enough. In either case I've never had my dish grounded in the 10 years I've had DirecTV and the coax only for the past 4.
