I am trying to point a 1000.4 western arc in the chicago area. I was unable to find the angles. I was able to find the angles for 1000.2 are the the same? I was unable to get signal with these. I also have 2 dpp44 switches in attic so I can hookup 6 boxes. Some legacy some new. Should I run a cable to only 1 box for setup? I have a small signal finder that I using to tune. Had no trouble tuning dish 500 before the dpp44 switches in attic.
