SO-239 hood?

[Rob Seastrom]

With the right tooling they're not horrible to put on.

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...

>>> I have seen an adapter 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.
