I'm getting closer to trying this but am a bit confused on the overall grounding of the antenna procedure. I found this:

and it mostly matches the other advice I've found online about the 8' grounding rod (which I'm not looking forward to pounding into our rock hard clay soil) and grounding block.
But it also includes running a wire back to the electrical box. With a cement slab house and the electrical box on the opposite side of the house that will be fairly difficult. It looks like if I don't do that I risk ending up with a ground loop between the house ground and my grounding rod.
