On Ken Kopp, K0PP's advice (nice call by the way), I checked for some markings. With bright light and a magnifier I find it's an Andrew 42W connector, of which there is little info on the internet. Except that it's for use with hardline, 1/2" I believe. But with some more poking around on the

Not sure you have anything to do the measurement, but the center pin of a 50 ohm type n male connector should be 0.0640 inches in diameter (this is the last part of the pin before it tapers to a blunted point). A 75 ohm pin will be 0.0353 inches. It's easy to tell if you have one of each, but unl
