Description
The RP-TNC (Reverse Polarity TNC) series is a specialized variation of the TNC interface, standard in wireless networking to comply with regulatory requirements for non-standard antenna connectors. In this Female (Jack) Bulkhead configuration, the connector maintains standard TNC female external threads but utilizes a male center pin instead of a socket. This variant is specifically optimized for the 2.5mm to 2.8mm (0.100″ – 0.110″) micro-cable class, providing a precision termination for versatile cables ranging from standard RG174 and high-temperature RG316 to low-loss LMR100.
Designed for cabinet and panel transitions, this connector includes a mounting nut and lock washer. The bulkhead D-flat (anti-rotation) design ensures the connector remains fixed during the installation process, preventing the body from spinning when the external antenna is tightened. Manufactured with a heavy-duty nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and low VSWR up to 6 GHz. The threaded design provides superior mechanical stability and EMI shielding compared to bayonet-style connectors, making it ideal for internal wireless module-to-external antenna routing.
Key Technical Advantages
-
Reverse Polarity Bulkhead Integration: Specifically designed for Wi-Fi routers and industrial gateways that require RP-TNC external ports for antenna connectivity.
-
Anti-Rotation D-Flat Design: The precision-machined flat side ensures a rigid panel mount, preventing rotation during cable mating and maintaining a reliable ground connection.
