Your low band is in trouble. This is often caused by loose
connectors, broken shields, bad cable or the like. I'll bet if you
connect a TV set to the same connector it will show the same problems.
It may even be a problem with the incoming cable, but if you have
good signal anyplace else in the house check the signal path carefully.
