After reading Shade's post about the improper installation of his satellite system, I became worried about mine as well. I purchased a Dish Network system through AllSat, and called a local place to install it for me, since I am not exactly mechanically inclined. Anyway, the man who came to do the work seemed pretty professional, and never gave me any inkling that there was something wrong. However, I looked outside, and I don't see any kind of grounding block. Is there anyway for me to check?
