Tom, whilst they are likely to withstand thousands of volts, small
coaxial cables are unlikely to withstand the heat from the
corresponding current if applied for sufficient time.

The focus in this discussion seems to be solely on the voltage
withstand capability, whereas loss / ability to dissipate heat /
temperature rise as installed are relevant and may be more
constraining.

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.
