The UHF connector, also called the Amphenol coaxial connector, is a World War II threaded RF connector design, from an era when UHF referred to frequencies over 30 MHz. Originally intended for use as a video connector in RADAR applications, it was later used for RF applications. This connector was developed on basis of a shielded banana plug. UHF connectors are generally usable through what is now known as the VHF and HF frequencies and can handle RF power levels over one kilowatt. Despite the name it is rarely used for actual UHF frequencies as they don''t work well above 300 MHz.
