Heavy cloud cover obstructs/blocks the satellite signal.No signal,no
audio and no video (except for a blue band across the bottom of the tv
screen that says Searching For Signal,or something like that) either,so
the tv screen goes dark and quiet.Sometimes though,the heavy cloud cover
isn't qute heavy enough to completly obstruct/block the satellite signal
and there are big stop action pixels on the tv screen and the
video/images on screen look as though they are frozen in place untill
the satellite dish antenna can pick up a better signal and the audio
sounds like it is breaking up,sort of like somebody loseing their cell
phone signal.
