Homeowner is renovating a cottage/guest house on his property. Just had a satellite dish installed on the edge of the roof. Besides the fact that the cable runs were an absolute mess (with a lot of it tangled in runs of Romex), there is not a single ground: nothing on the dish mast and nothing on the three coax cables from the dish. There is no intersystem bonding termination.
To make this compliant, I believe I need to do the following:
1. Attach a 10 AWG copper GEC from the mast to the GES.
2. Install an F Grounding Block (triple or quad port, depending on what I can get) at the cables' point of entry to the structure and connect with a 10 AWG copper GEC to the GES.
Questions:
1. Do I need a separate grounding electrode near the dish? (The dish is approximately 25 - 30 feet from the service sub-panel.)
2. Can the GEC for the mast also be used for the F Grounding Blocks? My guess is that it's ok, but that the GEC would need to be continuous. But I can't find a specific reference in section 810.21.
3. After entering the structure, the coax cables make a straight run toward the sub-panel. Is it acceptable to run the GEC along the same path? Would any separation be required (or recommended) between the GEC and the cables?
4. Is it permissible to bring the GEC into the sub-panel and connect it to the internal grounding bar? Or would it have to be connected to the GES outside the sub-panel?
Is there anything else I'm missing?
Closing comment: I suspect this is the norm, not the exception, for satellite dish installations. This was not the work of a handy man; this was a "professional" installation by a major satellite service provider. How do they get away with these violations?
