Over the air television - in and out fuzzies???

Leeblev, that makes good sense. At home, we do get multiple stations. We have two 8-1's, 8-2's, 8-3's, 8-4's. They come from 2 different locations. One television in the camper, when flipping through the channels will land on 8-1, then 8-1 again, where as the other television only lands on 8-1 once. If two broadcasts are sending at the same time, I can see how that would confuse the television enough to create a fuzzed screen. Thanks for the input!
