Back in the late 1980s, not long after cable came to town, we had
massive problems with crud all over VHF/UHF including a whopping
carrier on 145.25. In this case, it turned out to be poor
installation by the cable company, not anything subscribers did.
Several calls to the company resulted in denial of any problem. One
day we discovered we could get almost every cable channel by turning
our rooftop antenna toward a box (line amp?) on a nearby pole and
routing it to the cable box. After a subsequent call requesting our
cable be disconnected because we were getting it for free with a
rooftop antenna, a problem that was previously said to not exist was
miraculously fixed - and fast! They never entered any homes, but
replaced that box and associated connectors on the pole. The carrier
level on 145.25 dropped to a rather low level and all other crud
disappeared.
