UHF connector

Common card · No. 247848

The UHF connector is a name for a fairly common, but old type of threaded RF connector. The connector design was invented in the 1930s for use in the radio industry. It is a widely used standard connector for HF transmission lines on full-sized radio equipment, with BNC connectors predominating for smaller, hand-held equipment. The name "UHF" is a source of confusion, since the name of the connectors did not change when the frequency ranges were renamed. The design was named during an era when "UHF" meant frequencies over 30 MHz. Today, the meaning of the term ultra high frequency (UHF) is instead defined to be frequencies between 300 MHz and 3 GHz and the frequencies formerly called UHF are now called very high frequency (VHF). Unlike modern connector designs that replaced it, no active specification or standard exists to govern the mechanical and electrical characteristics of the so-called "UHF" connector system, making it effectively a deprecated design with no guarantee for suitability...
