UHF connectors - sometimes referred to as Amphenol connectors - are suitable for use through the HF and VHF frequencies. Despite their name, they are rarely used for commercial UHF applications because they experience signal reflections above 300 MHz due to their non-constant impedance. Although we carry many types of RF connectors, UHF connectors remain one of the most popular. This is largely thanks to their continued use in the amateur and marine VHF radio markets. They are favored for applications where durability is more important than any slight drop in performance that may come along with it. Male connectors sometimes go by PL-259, while Females are often referred to as SO-239. Both of these names are holdovers from their use by the Army Signal Corps, who relied on them heavily beginning in the World War II era. UHF connectors can handle over 1 kilowatt of RF power and feature a threaded design for easy and secure connections. They provide better power handling at lower frequencies than the similarly sized N connector. We have connectors compatible with all types of coax, including RG-8X, RG58, LMR-240, LMR-400 and more.
