Product details

The FA1-NHSJ-C04-0: It ships as a complete assembly kit — five pieces: the connector body, a crimp contact, a ferrule, a housing, and a locking clip — so you don't have to source each part separately.

Cable Compatibility — RG-58 and Beyond

This jack is listed for RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907. That covers the common 50 Ohm flexible coax types used in GPS antennas, cellular modems, and short-run RF interconnects.

The 4 GHz maximum frequency covers L-band GNSS, 2.4 GHz ISM, and most automotive telematics bands (SiriusXM at 2.3 GHz, cellular LTE up to 3.8 GHz). The 0.3 dB insertion loss is a single-connector figure — in a typical harness with two connectors (jack + plug), budget 0.6 dB total at 4 GHz.

Frequently asked questions

Is FA1-NHSJ-C04-0 compatible with RG-58 cable?
