On a similar note, I have been having trouble with my CATV reception, but in a
slightly different manner.  On the pay-TV channels which are scrambled
(Showtime, Sportschannel, Sportschannel America), I will get interference when
vehicles pass by the front of the building.  I live in a six-unit apartment
building along a fairly busy road, so this interference is frequent enough to
be obnoxious.  The first thing the cable company did was replace the drop from
the pole, saying that the old single drop couldn't drive all six apartments.
This fixed the problem on one of the channels, but not on the other two.  Any
ideas where the problem might be?  I assume that the descrambler for these
channels uses some sort of feedback loop, and the cable picking up
interference from the outside may be upsetting this.
