Product details

FME Plug for RG-58 — 50 Ohm, 200 MHz, Crimp Kit

The FME interface is a compact threaded coupling — smaller than a TNC, more secure than a BNC — and the 50 Ohm impedance holds the signal path clean for baseband video, GPS, land-mobile radio, and telemetry links up to 200 MHz. The crimp termination covers the cable group RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907, which covers the bulk of installed low-power coax.

Threaded Coupling and 500 Mating Cycles

The threaded fastening type locks the plug to the mating FME jack — a half-turn loose is a dropout, so the thread is your vibration-proofing.

Construction and Shielding

Brass body with nickel finish. Shield termination is crimp. Dielectric is PTFE.

Frequently asked questions

Is 081-169 compatible with RG-58 coaxial cable?

Yes, the 081-169 is listed for RG-58, 58A, 58B, 58C, as well as 141, 303, LMR-195, Belden B7806A, and 9907 cable groups. The crimp ferrule and centre contact are sized for these cable diameters.

What is the impedance of Amphenol RF 081-169?

50 Ohms nominal, which is the standard impedance for RF signal paths — matches the characteristic impedance of RG-58 and LMR-195 for minimum return loss.

Does 081-169 come with contact and ferrule included?

Yes, the kit includes three pieces: one connector body, one centre contact, and one ferrule. One order code gets you the full crimp set.
