[Elecraft] Trap designs with toroidal inductors

[Mike Zak]

 Can anyone on this list point me toward any references that discuss =
trap construction using toroidal inductors?  The application would be =
multiband dipoles.

Seems that now that my max QRO is 12 watts maybe designs that use =
toroidal inductors would make sense.  Some clever mechanical =
considerations, w.r.t. strain relief and weatherproofing, might make =
possible some clever designs.

Is the reason we've never seen much along these lines because (a) it's =
hard or (b) it's dumb, both being the two major reasons why you =
sometimes don't see things that might make mathematical sense.
