But Owen, I've used a variety of F connectors for hundreds of hours at
high power at lower HF and on six meters.

He asked if anyone had direct experience, and I stated what my first
hand experience with them was.

People would be amazed at the amount of power a good grade RG-6 style
cable will handle and how much power that F connector will take.

Tom, I agree with you. I use selected RG-6 cable myself, and it is
greatly undervalued. But... my point was mainly, don't focus only on
breakdown voltage, it is certainly a parameter that relates to
instantaneous failure, but heat from losses (principally ohmic loss in
the centre conductor) is an issue and may be more limiting. Of course,
average power under typical voice SSB service is perhaps 2% of the
PEP, so heat becomes less an issue than under higher duty cycle modes.

Discussion of F connectors inevitably leads to RG6. BNC connectors are
readily available (at least over here) for RG6 and are my preferred
choice.
