UHF Series RF Connectors
RF Connectors > UHF Series RF Connectors
Description
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.
Features & Benefits
- Optional reducing adapters accommodate a wide range of popular coaxial cables
- Solder termination types require no special assembly tools
- Crimp termination types provide a lower cost installation method
- Large-size threaded coupling is rugged design
- Non-demanding specifications and low cost
Applications
- Antennas
- Cable Assembly
- Low Frequency Applications
- Public Address Systems
- CB Radios
