I have my dish on the chimney and since I changed from the 500 to the hd 1000.2 dish my levels are bad. I believe i'm clipping the level from the roof line being in the way. My levels are 119 sig 77 110 sig 66 129 sig 30. 119 and 110 was good before I changed out my dish 500. I'm moving it to a pole soon hoping to improve the signal and i'm checking to see if my angles are correct, az 236 el 28 sk 125?
