Most of the leakage I've seen from CATV systems comes from poor Type-F
coax connector installations by home owners and unterminated coax
cables. It takes quite a bit of cable leakage to produce interference
with an OTA signal, but it might be possible in weak areas and if the
OTA TV system uses a pre-amplifier.



The OP is definitly in a weak area (45 miles from stations) and IS using an
aplifier just under the antenna. Anybody within a fe miles in the general
direction of the broadcast antenna could be trashing his signal. Without
the proper equipment (portable spectrum analyzer), it could be quite hard to
find the problem.
