Hi! I have a feeling that this is a pretty common question about satellite. From what I've read, the signal beams down from the transponders to the satellite dish. The dish then reflects it into the LNB which then carries it to the cable and into the house. I was wondering how large of a "beam" is beamed to the dish? I can't imagine it being kind of like a narrow "laser" beam. Is it a beam the size of a satellite dish (~18")? Part of me is just curious, and the other part wonders if the house they are building next to me will affect my signal. The house is about 100' away from the dish and is almost inline with the one outer edge of the dish. If you had to draw an imaginary pipeline from the dish to the sky, it would maybe (if that) just touch the outer edge. So far, I have no interference, but I'm just wondering at what point it will fade out. Thanks!
