It's a 50 Ohm connector rated to 4 GHz, built for RG-316 double braid cable. The kit includes 7 pieces: the connector body, bushing, contact, ferrule, gasket, lockwasher, and nut — everything needed for a single cable termination through a panel.
RF Performance and Construction
The 4 GHz bandwidth covers most test equipment, broadcast video, and instrumentation links — the 0.2 dB insertion loss is tight enough that a single mated pair won't eat your signal budget. The crimp shield termination gives a solid 360° bond to the RG-316 braid — critical for keeping the shield ground continuous at 4 GHz.
The 1-5225398-5 is listed as Obsolete by TE Connectivity. That means it's no longer in production and no direct factory replacement has been assigned. No official cross-reference or pin-compatible alternative is on record from TE.
