Thanks

I've been able to mail order most any electrical part from Mouser. No
minimum order. And it puts you on the list for their huge catalog.

vertical without having to cut it.

I did exactly this (20 years ago). I used a variable compression

trimmer
capacitor to check that I could actually get a low SWR, measured it,

and
fitted the nearest value disc ceramic (rated at 500VDC). I think it
was
330pF. No problems with 40W.

I once saw a 102" whip on a motor home that had literally been wound into
a 4 " dia coil about half way up! It looked like one of those CB "big
coil" trucker antennas except it was all in one piece. I can only surmise
that he heated it and wound it around some sort of form. It shortened the
thing down to less that 5 feet. But, then, wouldn't that take the temper
out of the steel and make it flop over the next time it was hit? There
was also no evidence of heating, either; it looked like it had been formed
at the beginning of its life. Anybody ever see anyone do this before. If
so, how was it done?

Wouldnt be that hard to do, You can retemper the steel if it gets soft and
the discoloring will buff off.
tempering metal takes some specific knowledge and experience. Ive done it to
tools and had some success but I have also made them to brittle and they
break.

Of course it may have been one of those big coil antennas
