I'm not sure that the military terminolg was PL-259 for the PLug type
259...I think that was Amphenol's terminology as (and while I forget the
actual number) the coaxial UHF plug and it's mating female chassis socket,
had an MIL-STD number when we had to order them from supply. They also had
an NSN, national stock number as well. Of course it's been 7 yrs since I
dealt wth mil part numbers and 12 since I've had to mess with those types.

=> I learned to call them Amphenol "Blue Ribbon" connectors. Like the D
=> connectors there were several sizes depending on number of contacts.
=> Guess they were named for their useage, like PL259 connectors were named
=> from the military stock number, rather than calling them UHF.
