[Amps] Vacuum coax T/R relay

[John Lyles]

My old Jennings catalogs show nothing like that. Two things that don't sound like Jennings, at least from the packaging you described. Jennings used either a circulator connector for their larger relays, or turret pins for the small BNC and type N. They didn't have any with SO-239 connectors. Also, they had two main configs, a box 1.35 x 2.2 x .75 inch with three BNCs on the narrow side (1.3x0.7),or a box that is more square, with connectors on three of the narrow sides. Of course it could be a special that they made, or could be a Jennings inside of a box made by someone else. 

Did you find that National R175A choke.
