TNC Miniature Connectors 

The Threaded Neil Concelman, or TNC, connector emerged in 1956 as an alternative to the bayonet coupling mechanism of the BNC. Utilizing the same basic structural parameters as the BNC connector, only substituting a threaded interface, the TNC was originally designed for military and aerospaceenvironments that had a high degree of vibration.

The TNC operates in frequency ranges between DC-11 GHz, and is often used in applications which have performance requirements that fall somewhere  between the capabilities of the SMA and the Type N. Some such applications include radar, base station, telecommunications and antenna systems
