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.
