Hi Nate,

Simply examine the transfer characteristics of any series or parallel,
resonant circuit. It has a peak, not a band-reject characteristic,
that is why it is called resonant. You resonate traps at one distinct
frequency where the roll-off may serve the purpose over a slightly
wider region. A 10M trap does not "remove" the surplus wire for all
frequencies above, say, 28.4 MHz, and probably doesn't work for the FM
portion of the band.


Honestly, Richard, your explanation was always my assumption and
understanding. W8JI seems to be saying that by resonating them lower the
benefit was lower loss. Now, I believe he was examining the 40m traps
used in W8NX's antenna featured in various issues of QST.

I think I ought to construct the durned thing and not worry about the
minutia. ;-)

Hi Nate,

That idea has a lot of traction.
