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.","metaTitle":"Amphenol RF 081-169 FME Plug, RG-58, 50 Ohm, 200 MHz","metaDescription":"Amphenol RF 081-169 FME plug, male pin, 50 Ohm, 200 MHz max.
