Yes, that conenctor (We generally call them PL259s and SO239s (plug
and
socket respectively) over here) was quite common on video equipment at
one time. I have no idea why, it's not even close to constant
impedance,
and it's very easy to make a right mess of soldering the plug to the
cable.
They go by the same designation over here. They're one of the
worst connector designs I've ever seen. Not even suitable for VHF
use, why on earth someone named them "UHF" is quite beyond me. Have
you ever put one on a network analyzer? Bumps and reflections all
over the place.
The BNC connecotr is a lot nicer.
Twisting two pieces of wire together is a lot nicer than a PL259/
SO239!
