UHF connectors, also known as PL-259 connectors or SO-239 connectors and it is a threaded coaxial connector commonly used in radio and television applications. It was initially developed for use in the UHF frequency range, but its use has extended to other frequency ranges as well. The UHF connector is typically used with RG-58 or RG-8/U coaxial cables. The RG-58 cable is thinner and more flexible, while the RG-8/U cable is thicker and has lower signal loss at higher frequencies.
