UHF connectors are sometimes also called Ampheno coaxial connectors. They were designed by Ampheno's designers in the 1930s and used as RF connectors in the radio industry. UHF connectors were originally intended to be video connectors for radar equipment, but later were used in various RF applications. The plug can be called a PL259 coaxial connector, while the socket can be called an SO239 connector. These are their original military part numbers.
UHF Male Crimp Antenna Plug Coaxial Connector for 5D-FB LMR300 Aircell7 Cable
Overview
TYPE UHF products is one kind of video frequency coaxial connectors with screw coupling and adopt tooth of end gearing. Impedance is not strictly defined, but usually applied at the frequency of 500MHz. This products are very suitable for the civil wave band communication system, closed-circuit television, the car radio device products etc. These connectors have characteristics of reliable connection, good vibration performance, and reasonable price.
