The outer body of a So-239 would be easy, but that inner part the
the center pin fits into would be trick to make. Also the crimp
they use to hold in the insulating material could be a problem. I
don't have any test gear, not the skill to figure out the
electrical qualities of these connectors. I seem to remember
seeing the specs for teflon vs bakelite somewhere. So often the
electrical specs just aren't given. My application in this case is
HF and I'm sure the old UHF connectors are adequate. I can almost
here the "tsk. tsk, tsk" of more serious hams wondering why I
don't use N connectors...<br class="">

for an SO-239 that allows you to connect a regular
4 bolt panel jack (SO-239) to the end of a bit of
coax. It is like a cone shaped hood with the top
shaped so you can solder the braid to it and the
wide part of the cone flares out so you can use
screws to attach the jack. IIRC it had a small
hole in the side to solder the center connector.
It was a stamping.<br class="">
