Product details

SMA Plug for RG-58 and Similar Coax — 12.4 GHz, Crimp/Solder Build

The Amphenol RF 901-9870 is an SMA plug with a male pin, designed for field-terminated cable assemblies using RG-58, RG-58A, RG-58B, RG-58C, RG-141, RG-303, LMR-195, Belden B7806A, or 9907 cable. It handles signals up to 12.4 GHz at 50 Ohm impedance, with a voltage rating of 500 V. Shield termination is crimp; the center contact is soldered. Threaded coupling secures the mated pair, and the free-hanging (in-line) mounting style makes it a straight cable-end connector.

Cable Group and Termination — What Fits

This plug is built for a specific set of coax cables: RG-58 variants, RG-303, LMR-195, and Belden B7806A/9907. The shield is crimped; the center pin is soldered to the cable's center conductor. For a different cable type, a different ferrule or connector variant is needed.

How It Compares: 901-9867-RFX and 901-9881-RFX

The 901-9867-RFX shares the same SMA plug style and gold body but is built for RG-405 semi-rigid cable (0.085"/0.086") and uses solder shield termination, not crimp. Its frequency rating reaches 18 GHz, higher than the 12.4 GHz of the 901-9870. The 901-9881-RFX is also a crimp/solder SMA plug but for RG-174/316-size cables, with a nickel body finish and a 375 V voltage rating. Choose the 901-9870 when the cable is RG-58 or LMR-195 and a crimp shield is preferred.

Frequently asked questions

Does the 901-9870 work with RG-58 cable?

Yes. The 901-9870 is specifically listed for RG-58, RG-58A, RG-58B, and RG-58C, as well as RG-141, RG-303, LMR-195, Belden B7806A, and 9907. The kit includes the connector and one ferrule; the center contact is soldered and the shield is crimped.

Is the 901-9870 a TNC or BNC connector?

It is an SMA connector — not TNC or BNC. The connector style is SMA, with threaded coupling.
