We have a client who previously had a 3LNB dish with (2) H10's up in northern Wis. We upgraded him to the Slimline 5 dish and (2) H20-600's. Signal from the dish is screaming using a birdog meter. After the install, the H20 for the kitchen tv pixelates as if you loose signal every once in a while only on HD channels. The H20 in the Gr Rm does it as well, but not that often. We did not have this problem with the H10's and we even mounted the new dish as high as we can go for a better signal. Does anyone have any ideas what would cause this? The "cabin" is a 3hr drive from our shop so an info we get before going back up would be great.
