John,

Thanks for the info.

What I've got are the .38 OD .25 ID ones. Thanks for the info. Seems
like I've been overkilling the VHF stuff. I think my 2m beam has 50 of
them on it, and if they're 12 ohms down at 7MHz...

I'll save that fair-rite link for future reference, but right now it's
locking my browser!

I guess the bead balun would be more broadbanded. I've not yet
measured the self-resonant frequency of my toroidal choke, but I'd
imagine it's somewhere in mid-high HF.

I think I'll string up a hundred beads and use that as my choke.

Thanks for the input es 73,

Dan
