[ARC5] [Milsurplus] Unknown Antenna

[Richard Knoppow]

    I am frustrated by not remembering. I saw a rather long 
discussion of this in a mailing list I subscribe to but can't 
remember if there was any conclusion. Every so often the origin 
of various connectors comes up, particularly the N, BNC, RCA (AKA 
phono plug) and other common ones. The SO type connector, AKA 
UHF, AKA VHF is not even a constant impedance connector but can 
handle a lot of power and is pretty rugged so its popular. So I 
am another who would like the inside story.
    FWIW, I have an RCA AR-88F, the one that was modified for use 
in a triple diversity receiver. It has an IF connector in the 
back for a monitor. This is an "Amphenol" jack of the sort used 
for PA microphones. The receiver was designed c.1940. This may 
just have been a common and convenient connector to use or there 
may not have been anything better at the time. OTOH, my memory is 
that the UHF connector goes back to the 1930s.
