Overview
The TNC connector (acronym of "Threaded Neill–Concelman") is a threaded version of the BNC connector.
Description
The interface specifications for the TNC and many other connectors are referenced in MIL-STD-348. The connector has a 50 Ω impedance and operates best in the 0–11 GHz frequency spectrum. It has better performance than the BNC connector at microwave frequencies. Invented in the late 1950s and named after Paul Neill of Bell Labs and Carl Concelman of Amphenol, the TNC connector has been employed in a wide range of radio and wired applications.
The TNC connector features a 7/16"-28 thread, not to be confused with a 7/16 DIN connector, which is the diameter of the mating surfaces as specified in millimeters.
