Hi,

Thanks for suggestions on Ferrite Bead usage from older post, and for all
the past help.
Sure is a lot to learn.

Have one question on the ferrite beads:

For my receiving only antenna.

If I put some ferrite beads over the coax run in from the antenna to the
house, wouldn't
the beads (also) degrade the incoming received signal level?

I guess what's bothering me is that I don't see how they can absorb
noise "selectively" from the actual signal (30 MHz on down) ?

What's some of the very basic theory behind how these things actually work,
then ?

Thanks,
Bob
