With several e-mails asking about coax rf chokes I decided to call Mosley today
since I'm redoing my Classic 33 WARC with the 40m kit. The rep on their tech
line gave me an unusal description that I had never heard before for a rf choke.
He said to start with a 10 inch inside diameter single coax coil then wrap 10
turns around, like you would if you were coiling a water hose on the ground or
for you Navy vets, a properly coiled of rope on the deck. This sounds like it
would end up being 15 inches or more in total diameter, a bit big for an RF
choke
isn't it? Then hang the whole thing perpendicular to the boom. I even called
their tech help line back later to be sure I had the directions correct and the
same person said the coil would make an RF choke, not an "inductor", his
terminology.
I've seen photos of and several Mosley beams in person, but none had an RF choke
like this one.
