UHF coax connectors reliably carries signals at frequencies up to 100 MHz with thread coupling. Widely used for Antennas, Military, Public Address Systems and Low-frequency applications etc…
UHF connector is designed in World War II or earlier, and invented in the 1930’s by an Amphenol engineer Edward Clarke Quackenbush for use in the radio industry. The most popular cable plug and corresponding chassis-mount socket carry the old Signal Corps nomenclatures PL-259 (plug) and SO-239 (socket).
Designed for low frequency systems from 0.6-300MHz;
Threaded coupling mechanism is easy for assembly with high durability;
