Amphenol's UHF connector series, invented in the 1930s, provides a general-purpose, low-cost solution for low-frequency systems. These connectors, designated with the “RFX” part number prefix, are ideal for commercial applications where high performance isn't critical. They feature a threaded coupling for secure connections and are often constructed with die-cast and molded components to minimize cost. While performance may not match industrial or military-grade connectors, they remain a versatile option for antennas, cable assembly, and public address systems. Optional reducing adapters accommodate a wide range of coaxial cables, and solder or crimp termination options are available for flexible installation.
