Kind of an odd specification number, but, since that connector probably
antedates World War II and all the modern style of specification (I'd expect
a MIL-C-xxx type spec for a connector), it could well be.
::It's really PL-259/SO-239. A type N is really UG21X/U (e.g., UG21B/U,
UG21C/U, UG21D/U) etc. A BNC is really UG88X/U (e.g., UG88C/U) etc. The
PL-259 reducing adapters really are UG175/U, UG176/U, etc. The
double-female adapter for UHF connectors really is PL-258. The applicable
mil slash sheets can all be found by the P/N, just as they can for tubes,
transistors, diodes and everything else. The one that cracked me up was
when, in researching mil specs, I came across the spec for the government
issue brown paper lunch bag. (It does have a spec, and a P/N.) Made me
wonder if they have a mil spec for the G.I. grilled cheese sandwich (rubber
on a raft...maybe MIL-S-ROR/1)...
Does the military even use PL-259/SO-239 type connectors any more? Most of
the specs I've seen recently call out TNC, BNC, N, and SMA for low power RF
(less than 20 GHz and less than a few watts) and "coaxial or waveguide,
subject to approval" for high power.
::Don't know if there's any current application for PL-259s other than
replacement parts nowadays. Might be interesting to find out, but not all
that interesting. Of all those types you listed, the PL-259 can handle more
power (than any of those), so maybe there's still some use for it. I'm
looking for the mil-spec waveguide-to-binding post adapter so I can use
ladder line at 24 GHz :) (WB2WIK/6)
