Common Use Cases
This cable assembly is essential for professional radio technicians building or maintaining commercial two-way radio systems, particularly when connecting Motorola mobile radios, repeaters, or base stations to external duplexers, combiners, or antenna systems. The N-to-QN configuration provides compatibility between standard threaded N-type equipment and modern quick-lock QN infrastructure.
About Type N and QN Connectors
Type N Connector: A medium-size, threaded, weatherproof RF connector invented in the 1940s by Paul Neill of Bell Labs. The N connector is widely used in commercial radio systems, spectrum analyzers, and antennas operating from 0-11 GHz. It features a robust threaded design that requires proper torque for optimal performance.
QN Connector: A quick-lock RF connector designed to replace threaded Type N connectors in telecommunications applications. The QN connector features a snap-fastening mechanism that allows for faster installation and removal without tools, while maintaining the electrical performance of traditional N connectors. Introduced in 2004, QN connectors are commonly used in cellular base stations, repeater infrastructure, and defense applications.
