I put an OTA module on my Wally. My home is in South Dakota and I am in AZ. On some channels I go to the guide and click on an OTA channel and it looks like is going to work and the screen goes dark. Signal strength says 90-100 but it won't work. And some of the guide info is wrong. It will show info from a complete different channel. Is it a defective tuner or the time zone difference or what the hell. And Dish was absolutely no help. I am 100% positive it is not an antenna problem.
