Not a good idea to run that long of a ground and through the attic. I would just use a 4' pipe at the dish, most likely point of contact with lightning.kay said:I mean to go the "proper way" i'd have to run a ground wire from my grounding block through my attic all the way out the other side of the house to get to the main electrical ground outside. I suppose i'm not against doing this, but it seems a bit strange, are there limits on how long the ground cable can be? It would have to be at least 75-100 feet to reach. I did a bit of google searching that does confirm exactly what you are saying, but there isn't any info on limitations.
