ALL GROUNDS MUST BE UNIFIED!! Thats why the want the box by the
service entrance. seperate ground rods can create a different voltage
on grounded things, like during a lightning strike, that can be
dangerous.

thats why phone ground, is unified to main house ground rods, incoming
water line with meter jumper etc, even satellite dsh grounds should be
part of a unified system

Satellite dish grounds are for the sole purpose of dissipating static
electricity. There's nothing electrical about them.

That doesn't mean that some officious slug hasn't mandated that they be tied
to the central house ground, but I can't see that it would server any
purpose.
