Browse UHF connectors

UHF coaxial RF connectors were one of the first RF connector series to be developed. UHF type connectors are general purpose, non-constant impedance connectors which operate from DC to 300 MHz. The 5/8"-24 thread coupling and clamp,crimp,twist-on, and solder terminations give the UHF the flexibility that has kept it one of the most popular coaxial connectors over the years.

Among the many applications of this low cost, low frequency device are antenna connections for CB radios, public address systems, audio, video, mobile radio, and test equipment.
