While considered an older design, TNC connectors remain widely used in many US-manufactured devices. Within the wireless communications industry the most popular device manufacturer using TNC connectors is Cisco, who almost exclusively use the connector on its 5G and LTE-HWIC mobile broadband modules.

The TNC Male crimp for L-400 cables is very simple to fit-off. After preparing the PTL-400 (or equivalent series) cable, the connector's centre pin is soldered to the cables inner conductor, and the outer body simply slides over the top until the pin is fully inserted and the body cannot be pushed on any further. The ferrule is crimped using a standard 10.89 mm (.429") hex die.

TNC Male connectors remain highly popular on a range of Cisco cellular modems, industrial SCADA and ICS radios, and 900 MHz packet data transmitters.
