I'm planning a new install, replacing Comcast cable. I've spent a lot of time running cables in my house, for LAN and distributed audio, and I've done my best to stay 'within code'.
I could do this install myself, but I don't have the time. I really want to get it done.
It seems most subcontracted DirecTV installers try to ground 'properly,' but aren't aware of the NEC rules - it's not part of the training, and it's not clear in the installation guides.
Where I want the dish placed is far from the service entrance, and whole-house ground, at the house back corner. The installer will want to place the dish at the front of the house, near the service entrance, because that is the easiest place - and near the service entrance.
I've researched grounding fairly extensively. This graphic gem from Mike Holt helps (link fixed):
Bottom line - what wire/cable can I run from the dish to the service entrance for grounding?
Looks like a 17 AWG copper clad steel messenger wire would suffice, for both mast and coax, according to the NEC guidelines and Mike Holt. Can people confirm? I've read of the need for a 10 AWG copper wire, for coax grounding.
(Water main is buried outside and behind drywall inside, not an option.)
Thanks so much.
