I was able to snag one of these for FREE! Not sure exactly who makes it. I know commscope still makes a 420, but this one is a bit older. only one snag. center pin on the 75 ohm N female is borked and gotta be replaced. (for those who don't know they use 75Ohm RG-11 for the harness)
Might be a long shot but before I go and dump $30 for a new connector anyone got a center pin for a 75ohm N female laying around?
