Buy a long 3/8"x24 bolt, hacksaw off the head, then expoxy some pipe
with 1/2" inside diam in over the end. Make sure the part extending
into the pipe is long enough.

Thanks, Irv. Possibly workable for me, but the threaded end needs good
RF continuity to the 1/2" tube end, which will be soldered to a helical
winding running up the fiberglass rod.
