Problem called in due to pixelation on multiple channels. Dish offered to move me to the AE. Worked for me as I was starting to shot through trees and $15.00 was a lot cheaper than cutting down trees! But even after the change out, and excellent signal, I'm still having drop outs or "pixelation" on some channels - local and others. It does not happen all the time and I have started recording the problem so I can show a tech. I figured unless I could prove it was doing it, they won't find the problem or fix it. Other then signal strength, what else can cause these drop outs?
