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
