It is NOT leakage in your transmitting antenna system. It MIGHT be,
but probably is not, leakage in the TV antenna system. A much more
likely cause is a pin 1 problem in the TV set or an audio system to
which the TV is connected. It also might be made worse by common
mode current causing radiation from the coax. A good coax choke
would kill that current.
There are many ways in which RFI and TVI can occur. Study that RFI
tutorial that I pointed you to, which explains most of them (the
ones I've thought of) in detail. Once you understand them, you can
then use the detailed advice in the tutorial to first figure out
which one(s) is(are) happening in your particular instance and FIX
it(them).
