Description

TNC CONNECTORS

The TNC connector or (Threaded Neill -Concelman) is a slightly smaller RF connector. Similar to the more common BNC, but featuring with a threaded weatherproof version of a 50 Ω impedance. The TNC connector typically operates in the DC-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. Due to the versatility and durability, the TNC connectors are often likely to be used in applications where the connector needs to survive vibration, providing reliable performance at high frequencies.
