Frequently Asked Questions
What cable attachment method does this connector use?
This connector uses a mechanical clamp compression assembly for the outer braid and a solder-style center pin for the inner conductor.
What mating connector does this plug connect to?
It mates with standard 50-ohm TNC female jacks and bulkheads with matching threaded coupling.
Does this connector cross-reference to military or legacy part numbers?
Yes. This connector cross-references to military specification SM-C-662884, National Stock Number 5935-00-905-1778, and Solitron / GRFF part number 166C.
Threaded TNC coupling was built for the setups where a push-and-twist bayonet might get bumped loose mid-transmission. Thread it down, solder the pin, and put that legacy bench or rig back in service.
