Tnc Connector
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 specific local regulations[citation needed], i.e. those from the FCC, which are designed to prevent consumers from connecting antennas which exhibit gain and therefore breach compliance. This is the case for the popular Cisco line of Wi-Fi products. RP-TNC can also be abbreviated as RTNC
75 Ohm TNC
Most TNC connectors are 50-ohm type even when used with coaxial cable of other impedances,[citation needed] but a 75-ohm series is also available, providing a good SWR to about 1 GHz. These can be recognized by a reduced amount of dielectric in the mating ends. They are intermatable with standard types.
Retail uses
Linksys, a manufacturer of consumer networking equipment, uses RP-TNC connectors for several of its Wi-Fi-certified routers, including the popular WRT54G.
Telex Communications, a manufacturer of hearing aids and audio equipment, uses TNC connectors on its Radiocom BTR-800 partyline intercom base station for the transmit and receive antennas.
Camplex, a Camera multiplexing unit, uses TNC connectors to send power/tallies/intercom to a camera. The camera sends back audio, video, and intercom. Camplex Website
Icom, a mobile telecommunications equipment manufacturer, uses TNC antenna output terminals in some models intended for the professional VHF PMR market.
Electro-Voice, a pro audio manufacturer, uses these style connectors on their wireless microphone systems.
