Very true. The 'worst of the worst' seem to be the 5.1, 6.1 and 7.1
Surround Sound systems that folks add on to their big-screen TV's. The
speaker cables that come standard all seem to be about a quarter wave on 20
meters, and on my own system before I added ferrites on the leads, I could
blast myself out of the room with 100 Watts on 20. Ferrites on all the
leads going in and out of the box fixed the problem 100%, even at 1.5 kW.

The hoorah about RF on the outsde of the coax is much less a problem
now that we have gone to Digi TV and cable services for the most part.
At least in respect to TVI.
Most RFI in today's world is NOT to TV receivers, but to AUDIO equipment
(including computers), and it is mostly the result of pin 1 problems. The
rest is lousy (or non-existent) shielding.
But RF off the feedline CAN be an important contributor to that.
