=================================
Yup! Fred ... Soldered, Hex Nut BNC connector. As far as who fashions it
... Why not the homebuilder? After all the homebuilder was not born knowing
how to rivet, why not just learn how to do a proper BNC connection. They are
SOOooooo much better, water proof (or at least highly resistant), vibration
proof, dust proof and of course a damn good RF electrical connection. AND
you can
do a field repair on them. Can't do that on crimp crap.
The BNC was born out of the SO & PL fittings. It is better for maintaining
the impedance of the cable especially at low power VHF frequencies. The
higher
power, higher frequency version is the Type N.

We haven't use a solder-n-clampnut connector on a production
airplane in probably 25 years. I'll bet nobody on the production
line was sorry to see them go either. Ease of installation and
consistency of the electrical joints made it a no-brainer.
I keep some UG-88 clampnut connectors around to build adapters
and test tools. The wide open, threaded rear barrel is skunk-werks
friendly. But when putting a connector on a coax, wouldn't consider
anything other than crimped connectors.
