Invented in the 1930's by an Amphenol engineer named E. Clark Quackenbush,
UHF coaxial connectors are general purpose units developed for use
in low frequency systems from 0.6 - 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.
