OK, one more crazy idea on grounding -- tell me if I am off base here.
Let's say I put in a grounding rod at the center of the house, and I run the coax ground and the mast ground to that rod. (Which was option b.) Except, instead of running 6AWG wire to the service panel grounding rod in order to bond them, can I just run 6AWG wire to the plumbing pipe, which I know runs under the house and is connected to the service panel grounding rod anyway? In other words, is there some advantage to running a separate 6AWG wire to bond the two grounding rods, or is it sufficient that both rods are bonded by virtue of being attached to the plumbing?
The reason I'm focused on this is that it will be a pain in the neck to run 6AWG from a grounding rod at the middle of the house all the way to the service panel grounding rod. I'm not concerned about the expense; rather, there isn't any convenient way to get it there. The entire area is a bricked patio, so I couldn't bury the 6AWG. I also can't run it above ground because there are doors, etc, and we can't just have the wire dangling in front of the doors. I do suppose it would be possible to run the 6AWG back up to the roof, then across the roof to the other end of the house, then down to the service panel ground; would that work?
