The cables from the dish are coming from the dish to a splitter and grounded to a water pipe. They ran the cables along the roof an nailed them the the roof. I am putting a new roof on NOW and i want to run the cables inside the attic. The problem is that the splitter will also wind up in the attic. I have no water pipes in the attic for a ground. They moved the splitter close to an electrical box and grounded it to the ground wire in the box.Is this a bad idea?
