Product details

SMB Fakra Plug for RG-58-Class Coax

The body finish is nickel over brass, and the dielectric is PTFE for stable impedance up to the rated frequency. This plug is intended for field-termination onto RG-58, RG-58B, RG-58C, RG-141, RG-303, LMR-195, Belden B7806A, or Belden 9907 cables. The panel-mount flange with a Code K keying feature ensures correct orientation in multi-port applications.

Rated at 50 Ohm characteristic impedance with a maximum operating frequency of 4 GHz, the FA1-NKSP-C04-1 delivers an insertion loss of 0.3 dB across the band. Cable compatibility is explicitly listed for RG-58 variants, LMR-195, and several Belden types — the crimp ferrule and centre contact dimensions are matched to the 0.195-inch (nominal) dielectric diameter of these cables. For builds using a cable not on the list, verify the dielectric OD and braid coverage before committing to this plug.

Frequently asked questions

Is FA1-NKSP-C04-1 compatible with RG-58 cable?

Yes, the FA1-NKSP-C04-1 is listed as compatible with RG-58, RG-58A, RG-58B, RG-58C, RG-141, RG-303, LMR-195, Belden B7806A, and Belden 9907 cables. The crimp termination is designed for the 0.195-inch nominal dielectric diameter of these cables.
