The other thing i pondered is that it seems the don't make
Pl259/so239 connectors for hardline, so what do guys use typically for
higher power DIN?

Good to Gigs at 5kw. I recall a test of Pl259/SO239 connection vs. N found
the PL259/SO239 to fail from overheating due to the internal mismatch with
as little as 500 watts at UHF frequencies.

I don't recall the Maximum at HF, but High SWR is a consideration. Best to
use open wire feeders in that case.

N is a 50 ohm connector, but the PL259/2O239 is a stepped transistion and
isn't even specified for impedance.



JB sez "N is a 50 ohm connector, but the PL259/2O239 is a stepped

Actually, think you will find that N connectors, as well as BNC
connectors come in Several Impedences! (Not one size fits all).

Had surplus ones with center pins fit 90 ohm, and 75 ohm (no go on 50
ohm coax)! Be sure to check connector specs! Jim NN7K
