[Antennas] inline female coax connector?

Don, we can go with your connector-count, but I wouldn't be sure that
manufacturer measurements of loss include the PL-259 on *our* coax when
plugged into *their* connector. In fact I'll be willing to bet they do not
count your equipment, even though of course it is required to form a
"connection". That's not being deceptive, it's just not totally honest
either.
After one connector on the back end of the transceiver, two at the tuner,
two more at the lightning arrestor, and one more at the balun, that's enough
connector-loss in a system for me. There is no way I would add however many
more you count when a barrel connector would be used for a "patch cord".
It's a minimum of three more pieces (loss) that do not have to be there.
