silly question time

Silly question...

KPA100 / KAT100 have S0239 chassis sockets for the antenna connectors. I
can't find SO239 line plugs. I'm guessing SO239s mate with something
else, and it doesn't seem to be a PL239 either.

I'm PRETTY sure it's a PL259, but before I order something stupid,
thought I'd check. Right?

Yes, the SO-239 and PL-159 designations originate from the US Army Signal Corps component nomenclature system that was in effect before mid-WWII.  Therefore, you won't find a logical paring of socket SO-239 to a mating plug PL-239, for this or any other socket-plug combo.  That would have been be too easy.

Ha! We live with this stuff for so long we forget that it's not "obvious"
too.

Along those lines you'll often see that pair called "UHF Connectors". Well,
they were the state of the art in the 1930's when Amphenol developed them,
and back then "UHF" started at about 30 MHz. The VHF designation hadn't
appeared yet. There was just Low Frequency, Medium Frequency (roughly the
U.S. A.M. 'standard broadcast band' and the Marine band just below it), High
Frequency (the 'short waves') and Ultra High Frequency (where it was a
challenge to make anything work).

And over half a century later they are still excellent connectors for what
used to be 'UHF'.

Or classified  ...  didn't "loose coax connectors sink ships?"

Oh yes, there are no stupid questions, unless you're a politician.
