Directv advertises that there a only short and momentary loss of picture. That is a flat out lie, because every time there is a heavy overcast ( it doesn't even have to be raining) my sound and picture disappear. As I type this it has been 25 minutes since the picture died, and this is momentary???
They sent me a new receiver which their tech aligned and this problem still occurs.
I cannot ever recommend Directv to anybody who is looking for trouble free viewing
