UHF connectors are general purpose units developed for use in low frequency systems from DC – 300 MHz. Invented for use in the radio industry. UHF connectors are popular and economical, used when impedance mating is not required. UHF connectors were replaced in many applications by designs that have more uniform impedance over the length of the connector. UHF connectors were also used for the input & output of Composite video signals for older video equipment
