[Milsurplus] old USN patch panels and cords

[Nick England]

What is the name/number for the USN antenna connector used on the RBB/RBC
receivers and Navy antenna patch panels? (About the size of a UHF connector
but not threaded).

Any ideas as to where I can get this style of patch cord or connectors to
make some cords? - I'm still working on my basement COMMSTA.

Thanks,
Nick
