BNC Jack for RG-174/188/316 — 50 Ohm, 4 GHz
It comes as a three-piece kit: the connector body, one crimp contact, and one ferrule — everything needed to terminate a single cable end. The bayonet lock gives a quarter-turn mate that holds under vibration without tools, and the 500-cycle mating life suits field-service and test-bench reconnections.
This jack is dimensioned for RG-174, RG-188, and RG-316 coax — cables used in RF patch cords and internal equipment wiring.
RF Performance and Ratings
Rated 500 V and 0.2 dB insertion loss at 4 GHz, the 413779-3 covers the full BNC band for instrumentation, telecom, and low-power RF. The gold-plated beryllium copper center contact keeps contact resistance low through repeated mates — important when the connector lives on a spectrum analyzer or signal generator port that gets swapped daily. The 500-cycle rating is realistic for lab and field use; after that, the gold plating on the center pin begins to wear and insertion loss starts to climb.
