The beads will do no good for other RV'ers. They are suffering interference
for one of two reasons:
1) Your rig is radiating a harmonic or other VHF spur on the TV channel they're
watching. The LPF will take care of it.
2) Their TV is overloading from your strong nearby signal on HF, no matter how
clean it is. They need to install a high-pass filter on the RF input of their
TV or VCR or whatever is used as the tuner. (If they are using a DVD or VHS
player as the tuner, the TV is just used as a "baseband audio/video" monitor.)
If they are receiving interference on just one or two channels, it's a
harmonic. With a LPF, your troubles should be over.
If they are wiped out on all channels (most likely), it's overload - buy them a
RadioShack filter. These are cheap - get a bunch. Don't try to convince them
their TVs and VCRs are junk (even though it's their fault), but tell them it
will reduce interference from all kinds of things like illegal CB'ers and AM
broadcast antennas. Put one on your TV and tell them it's the greatest thing
since sliced bread.
You'll also meet the chronic complainers that won't be satisfied ever. Give
them a metal colander with a bungie cord. Tell them to wear it all the time so
the aliens or gummint (pick the one most they're most likely to be suspicious
of) can't read their thoughts. Wish them a good day and close the door.
