I have the reduced size BAU and it's on a tree 100' away from camper. I have the Directv splitter installed under the camper. Camper has 2 satellite in plugs on outside. My question is where to ground? I have an 8' half inch copper rod which I could drive in either by the tree or next to the camper. If I should ground by the camper, do I use a grounding block OR just go right off the ground on the splitter itself?
