At a hamfest a couple of months ago, a guy was selling some neat split
ferrite beads. The idea is a little like the snap-on rectangular ferrites
that Radio Shack et al were selling, except that these involve a split bead
1/2-3/4" long enclosed in a plastic shell that can be snapped open and
closed. He had 2 sizes, for different sized cable. Does anyone know of an
economical source for these? Strikes me it would be really handy to bring
a bag of them along on my next RFI-hunting project, because they would let
me assess and maybe cure lead pickup without ever having to disconnect any
of the neighbor's wires.
Second topic -- I'm looking for recommendations on a high-pass filter for
75-ohm TV leadin. I have one neighbor who is not on cable, and with my
antennas pointing toward him he has moderate fundamental overload TVI but
(thank goodness) no telephone or other RFI. What do people think is the
most cost-effective high-pass unit out there? The best at any (reasonable)
cost?
