UG-349/U(40) Connectors, Interconnects

The UG-349/U, connected to a coaxial line as a supplemental connector, is a common type of coaxial connector used in the RF (radio frequency) applications. It is also known as a threaded coupling, Category U connector, or UNEF (National Electrical Manufacturers Association) type connector. This type of connector is robust, designed to remain firmly in place even under high vibration conditions.

UG-349/U connectors optimally work in the frequency range of DC to 11GHz. This product is designed for applications including air traffic control, weather monitoring, instrumentation, military communication, wireless communication, data acquisition, and more. Their uses range from consumer and commercial radio transmissions to high-power transmission line applications.

The UG-349/U connector consists of a crimpable body, a threaded nut and a ferrule. The ferrule is a small tubular component, normally made of brass, which provides the electrical connection between the connector and the coaxial line. The ferrule is inserted into the crimpable body of the connector to ensure the proper electric connection. The threaded nut is then screwed into the crimpable body. The knurled surface outside of the crimpable body provides a firm grip for manual installation, while the threaded section of the nut is designed to securely and finally lock the connection to the line.

UG-349/U connectors are available in two configurations; male and female. The male version is equipped with a mating thread, while the female version is made with an interior thread for mating. Each configuration has a unique electrical design that ensures proper electrical contact and secure connections. The male version provides direct connection to the coaxial line for increased performance. While the female version offers the convenience of being able to use the connector with other types of adapters.

The key to successful RF transmission is to ensure that the connections are secure and the noise level is kept to a minimum. It is recommended to use UG-349/U components and accessories whenever possible, as they provide reliable and quality electrical connections in a wide variety of high frequency applications. The installation of UG-349/U connectors is a straightforward process, and can be accomplished with simple tools and minimal effort.
