Nope. But that doesn't change my opinion that the PL259/SO239

I have to agree there. :)
They're
one of the worst connector designs I've ever seen.
Show me a connetor design from the 30s that will take RG8 low loss
coax
and handle several KWs of RF power without arcing and sparking.
You will not do it with a BNC. PL259s are easy to terminate with a little practice
and a good
soldering gun!
...and then you have coax terminated with a crappy connector
that's not waterproof, lossy, easily contaminated, and has a huge
impedance bump.
Twisting two
pieces of wire together is a lot nicer than a PL259
To get closer to being on topic, try soldering 3 or 4 pieces of
coax to a DB9 connector to use as a RGB
video feed and look at it on an analyzer, it makes a PL259 look
like a real clean option. I agree the PL259 is overkill for 1v composit video,
but they do
have their uses.
Eh. There are SO many better connectors. BNC, TNC, N (my
personal favorite), APC-7...
