My best friend have DN services, So thats mean the dish is set correctly. He got 2 new cw800 today, We load the latest BIN , did the settings, scan Bird , enable patch and everything works but this is the problem, When i go to menu, anntena setting, installation i got 90% quality and 90% strenght on both 119 and 110. And also on both STB . But, when i go back to watch TV it works but if i change the channel and go back to the last channel strenght is there but no quality at all. So basically when i go to anntena settings i got 90% all the time on both 119 and 110, But when i go back to watch TV it works fine but once i start changing channels strenght stay but quality is gone. Help Please.
