Thanks for the info but cant do. I just looked out my patio where the dishes are. The one at 61.5 I could move but then I would lose my local hd and lot of the other hd channels. The other dish that I receive 119/110 is next to the brick wall and no way to move in that direction of 72.7You can check the "list" near the top of the page to check, cause there might not be any nationals on 77; if not, just use the 500 for 72.7, as long as your locals aren't on 77.
