HBR TNC Male Connector for L-400 Cable, Solder Contact
Locally Stocked

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 3G and LTE-HWIC mobile broadband modules.

The TNC Male crimp for LMR-400 cables is very simple to fit-off. After preparing the LMR-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.

Recommended Use

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

Cable Suitability

L-400, sometimes referred to as LMR-400, is a low loss coaxial cable with a large 10.16 mm outer diameter. Supporting frequencies beyond 6 GHz it's a popular choice for entry- to intermediate-level wireless communications systems.

This cable type is preferred over its smaller diameter compatriots when connection over the upper 4G LTE bands is sought, such as over B3 (1800 MHz), and B7 (2600 MHz).
