Threaded Neill-Concelman connector
From Free net encyclopedia
The threaded Neill-Concelman (TNC) connector is a threaded version of the BNC connector. 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.

Variations
Reverse polarity TNC
Reverse polarity TNC (RP-TNC) is a variation of the TNC specification which reverses the polarity of the interface, this is usually achieved by incorporating the female contacts normally found in jacks into the plug, and the male contacts normally found in plugs into the jack. RP-TNC connectors are widely used by Wi-Fi equipment manufacturers to comply with FCC regulations designed to prevent consumers from connecting aerials that might breach FCC regulations to WiFi devices. This is the case for the popular Cisco line of WiFi products. RP-TNC can also be abbreviated as RTN.
Retail uses
Linksys, a manufacturer of consumer networking equipment, uses TNC connectors for several of its Wi-Fi certified routers, including the popular WRT54G. Linksys also sells addon antennas for its routers which use the connector.
