Frequently Asked Questions
What mating jack does this connector work with?
It couples with any standard 50-ohm female BNC jack using the standard two-lug bayonet twist-lock mechanism.
Can the center pin be soldered instead of crimped?
Yes. The gold-plated center pin features an inspection hole and accepts either a crimp tool or standard wire solder.
What military or federal part numbers cross-reference to this connector?
This connector matches CAGE code 91836 and cross-references to National Stock Numbers NSN 5935-00-937-2664 and NSN 5935-00-169-3751.
A proper silver-plated Kings BNC is the kind of hardware that makes you want to trim your coax just a little cleaner. Crimp it down, twist the bayonet, and let the signal run.
