"RP-TNC" stands for "Reverse-Polarity TNC". [RPTNCConnector RP-TNC Connectors] are the cousins of [TNCConnector TNC-Connectors], and provide identical performance.



Reverse-Polarity connectors differ only by the gender of their center contact. For example, a male plug has a female center contact.



Reverse-Polarity connectors are commonly used on [802.11] gear due to America's [FCC] requirements (Part 15.203) where by such equipment needs non-standard connectors. Although less common, another modified [TNCConnector TNC] solution to satisfy the [FCC] requirements is to use a "[RTTNCConnector reversed-thread]".
