Hi all, I have an older house and I just had DTV installed. The problem I face is that some of the receptacles in the house have a ground and some do not. The receptacle that the main DTV receiver plugs into does not have a ground wire. There is a grounding rod outside, though I don't think it's buried that deep because there is so much rock beneath the soil that it'd be nearly impossible to drive in a grounding rod more than a few feet, and it feels loose when I try to move it around. So, being that as it is, would I be better off not having the coax from the dish connected to the grounding rod? I just don't want to create an unsafe situation because of a potential difference or ground loop, if my situation would cause either of those.
