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.
All grounds must be connected together. While the dish ground is to
dissipate static and such, it still must be connected to the other ground
rods . Lets say it is not. If for some reason the other ground rod comes
loose from the house wiring and there is a short that should go to ground
and it doesn't , and you decide at that time to plug in the dish , you
complete the path to ground and get shocked or worse.
Also if a lightning strike is near the house it is possiable to develope a
big differance of potentional between the two ground.
