[QUOTE="archive10, post: 919046"] The earth bond bar is required in professional installations in the States to comply with electrical codes. I think this is mainly to do with protection from lightning strikes on free-standing dishes. However, I also seem to remember reading about the risk of a potential difference between the antenna's earth, and a house earth (through your receiver equipment) in case the antenna ground spit is too far from the house ground spit. I think the solution was to carry ground to the dish too. Or something like that.
