What opinion would you defend until your last breath?
Mine: PL259 is an awful connector.
@tryst BNC forever
@renbymon Paul Neill and Carl Concelman were legends. Neill also invented N-type connectors, which we can all agree is the superior connector for UHF.
@renbymon Same. It's way more convenient for field work, and is a very acceptable connector for 0-800 MHz, and less than 400 W. So nearly /P stuff unless you are playing in the microwave bands.
800 MHz to 4 GHz gets increasingly wappy (technical term). You can sort of get away with them on L-band (26 cm), but TNC is better. On S-band (13 cm), you are asking for trouble.
In theory, it can handle up to 1.25 kW, but my EW experience suggests that this isn't a good idea as things start to get distressingly warm.
