UHF coaxial connectors were on of the first RF connector series to be developed. They are a general purpose, non-constant impedance connector which operates in low frequency systems from DC to 300 MHz. Invented for use in the radio industry, UHF is an acronym for Ultra High Frequency because at the time 300 MHz was considered high frequency.
UHF connectors feature a threaded coupling. Because these connectors are low-cost, the impedance is variable.
The 5/8"-24 thread coupling and clamp, crimp, twist-on and solder termination provide the UHF with the flexibility that have kept it one of the most popular coaxial connectors over the years.
UHF connector are used for radios, public address system, audio, video, mobile radio and test equipment.
