UHF / M
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.
Frequency Range: 0 - 300 MHz
Voltage Rating: 500 volts peak
Mating: 5/8-24 threaded coupling
Cable Affixment: Braid solder, set screw, clamp and crimp
Note: These characteristics are typical but may not apply to all connectors.
