TNC RF connectors are basically BNC connectors with threaded coupling and improved electrical performance at higher frequencies. TNC 50 ohm connectors provide repeatable electronic performance from DC to 11 GHz. TNC 75 ohm connectors are suitable for applications up to 1 GHz. All 50 and 75 ohm connectors are intermatable. TNC connectors are designed to accomodate cables from .150" to .250 OD. The TNC type connector is a weatherproof unit and with its threaded coupling ensures low noise and withstands shock and vibration. LTI TNC connectors are designed to conform to MIL-C-39012 specifications. Typical TNC series coaxial connector applications include airframe, missile, radar, cellular mobile phones, and precision electronic equipment industries.
