The UG-491/U(40) is a coaxial connector, also known as an RF (Radio Frequency) adapter. It is designed to allow for a connection between two radio frequency components such as an antenna, radio transmitter, and/or receiver. It is a 40-pair (pair = one signal and one ground connection) UG-491/U family of connectors commonly used in high-frequency military/aerospace applications.

The UG-491/U(40) is a miniature, lightweight connector with a threaded coupling nut that permits easy and firmly connected connections for reliable performance. It has a crimp-style or soldered center conductor, and is resistant to water, at least with regard to its external environment. The inner conductor is typically a ferrule ring and the outer conductor is typically a threaded-pin.

The major application fields of UG-491/U(40) are electronic warfare, instrumentation, satellite communication, radar, navigation, medical, and avionics. In addition, it can be used in communication networks such as GSM, CDMA, CDMA2000, TD-SCDMA, WCDMA, etc. It is useful for microwave and millimeter wave applications, high-frequency test and measurement, as well as antennas.

The operating principle of the UG-491/U(40) is simple. It acts as a barrier between two radio components, which transfers the signal of one component to the other without any loss of signal energy. As the connection is secure, there is minimal possibility of signal interference. When the connector is removed, both components are not able to communicate.

The UG-491/U(40) is highly preferred for its engineered metallic construction, precision-machined parts and reliable performance. It is also preferred for its easy setup process and cost efficiency. Its special body design is specifically engineered to reduce insertion and extraction forces, and its bayonet mounting facilitates quick replacement during maintenance. Furthermore, its plastic coupling nut has superior insulation and excellent corrosion resistance.

The UG-491/U(40) is a widely used adapter in numerous applications. It provides tight, reliable connections and is the perfect choice when a reliable, low-noise and temperature resistant connection is needed. Its compatibility with multiple radio signals, its low-loss operation, and its cost-effectiveness make it a great choice for RF connector applications.
