TNC CONNECTORS
The TNC connector is a threaded weatherproof version of the BNC connector with a 50 Ω impedance and operates best in the range of DC to 11 GHz frequency spectrum. Most TNC connectors are 50-ohm type even when operated with coaxial cable of other impedances. However, a 75-ohm series is also available, providing a good SWR to about 1 GHz. The TNC series shares its interface design with the BNC series, utilizing a threaded coupling nut to ensure mating and higher frequency performance than the BNC.
Because of the versatility and durability, TNC connectors are excellent for a variety of applications.
