There was a strong wind storm here in Phoenix last night and I am afraid it caused my AT9 dish to move slightly. I noticed that the picture for the locals (ABC, NBC, etc.) is horrible, but the other channels seem ok. I have the H20 receiver and a signal strength of 75 on the 101, 59 on the 119 and 67 on the 110. I did not check the 99 or 103 yet. I hate to call an installer out, but I may have to unless it is easy to tweak the dish. Any suggestions?
