The 300 MHz frequency ceiling and 500 V rating place it firmly in the classic UHF territory — think two-way radio base stations, antenna feeds, and low-VHF broadcast links where the signal path doesn't push into the VHF/UHF data band. The threaded coupling nut gives a positive mechanical lock; hand-tight should seal it for most indoor or sheltered outdoor runs. ## What Comes in the Kit and How to Terminate The package includes three pieces: the connector body, a coupling nut, and a ferrule — no need to order those as separate line items. Termination is crimp or solder, so you can crimp the center contact for production speed or solder it in a field repair. The shield termination is push-on, which mates the braid to the connector body without a separate clamp ring. ## Cable Fit and Signal Path The cable group covers the common RG-58 variants plus LMR-195, which is a low-loss drop-in for RG-58 in longer runs. The impedance is non-constant — this is a UHF connector, not a 50 Ohm precision interface — so it's suited for applications where a few ohms of mismatch at the connector interface won't degrade the system. The dielectric is phenol formaldehyde (phenolic), a legacy material that handles the 500 V rating and 300 MHz ceiling without issue. Single-port design, one male pin.","metaTitle":"Amphenol RF 83-58FCP-RFX UHF Plug, 300 MHz, RG-58","metaDescription":"Amphenol RF 83-58FCP-RFX UHF plug, male pin, crimp/solder termination. 500 V, 300 MHz max, RG-58/LMR-195 cable group.
