Interesting -- I'd assumed Rich was referring to the W2DU bead choke type.
I know they have some reported deficiencies at low frequency due to uneven
heat distribution along the string of beads, but hadn't considered using a
toroid and some teflon coax instead. Has anyone measured the performance
of such a choke balun at 160m? What core material would be appropriate?
