Helping a friend here setup his DirecTV stuff. While I have some experience with Dishnet and the general technology, I am not that familiar with the newer Direct stuff. He has a HD Dual Tuner/Pvr unit, brand new but not sure of the model (I can check if needed). We are in a very weak signal area, and his existing setup is two 33" dishes. I helped him aim one at 101W and he is getting TV off that just fine. However, none of the "Locals" are coming in, and we are not sure which satellite to aim the 2nd dish at to get them for the Nogales area. That was the first problem. The second is he popped for the HD service as well. We were told that a "larger" dish was needed in this weak signal area. No problem, we can do that, but WHICH satellite do we aim for to get the HD stuff. Is it on one satellite or more? And lastly, do they make a "switch" to tie these 3 dishes together? I know his old setup had a 22Khz switch, but that only handled 2 sats. Are there switches for DirecTV that handle 3 sats into one Dual Input box? Thanks for the help! Sorry, I put in breaks for paragraphs but they didn't take!
