 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.
