Specifications for UHF Connectors
_____________________________
UHF style connectors are inexpensive, general purpose connectors with non-constant impedance for use at
500 volts or less, and for use with low frequencies to 200Mhz for best performance, or to 500MHz but with
diminished performance. These coaxial connectors are widely used in citizens band communications,
CCTV, public address systems, mobile radio equipment, civil defense, ship to shore communications,
antenna connections, landing systems, and ground control apparatus. UHF connectors use a 5/8-24 threaded
coupling. They are available in a wide selection of sizes to fit various cable sizes.
