UHF connector
The UHF connector is one of the classic HF connectors. It dates back to 1930 and was developed by Amphenol. Although the designation UHF suggests that this coaxial connector covers the entire UHF band, the transmission frequencies only extend up to 300 MHz, i.e. for shortwave and VHF. In shortwave, it is also known as PL connector.
The general-purpose and inexpensive UHF connector has a screw thread (5/8") and Teflon or a comparable plastic as dielectric. It can be connected to many coaxial cables with different strengths and impedances. The UHF connector is available with 10-mm and 7-mm cable openings. It can be used in a temperature range between -55°C and 160°C and with voltages up to 500 V.
The UHF connector is used in antenna systems, in the VHF television and shortwave range, and in CB radio. In addition to the standard UHF connector, there is also a mini UHF connector.
