That is everything needed to terminate a cable end — no separate hardware order for the panel mount hardware. ## Cable Match and Assembly This jack is built for RG-179 and its variants (179A, 179B, 187, 187A, Belden 9221, M17/94-RG179). The crimp ferrule and center contact are sized for that cable group — wrong die, wrong crimp. Use the manufacturer-recommended crimp die for RG-179 to get a gas-tight connection on both the braid and the center conductor. ## Electrical and Mechanical Ratings 50 Ohm impedance, 4 GHz maximum frequency, 500 V voltage rating, and 0.2 dB insertion loss. The 500 mating cycles are standard for a bayonet-lock BNC — fine for bench use and patch panels where the connector sees daily reconnections. The dielectric is polyoxymethylene (POM) acetal, which holds up to the 500 V rating without tracking.","metaTitle":"031-245-RFX Amphenol RF BNC Jack, 50 Ohm, 4 GHz, Panel Mount","metaDescription":"Amphenol RF 031-245-RFX BNC jack, 50 Ohm, 4 GHz max, 500 V.
