• About UHF Series

UHF coaxial connectors were one of the first RF connector series to be developed.

They are a general purpose, non-constant impedance connector which operating from DC to 300 MHz. 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.

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