TNC series is a commonly used coax connector. The same size as BNC connectors, but with a threaded coupling mechanism, this connector can be used up to 11 GHz. Both 50 Ω and 75 Ω impedances are available. 

Applications for these connectors range from signal and data to video transmission where vibration resistance is required. TNC are a low-cost high-frequency solution for coax connections.
