Description
The RP-TNC (Reverse Polarity TNC) series is a specialized variation of the TNC interface, designed with a reversed center contact to meet regulatory requirements for non-standard antenna connectors. In this Male (Plug) configuration, the connector features standard TNC male threads but utilizes a female center socket instead of a pin. This variant is optimized for the 5mm (0.195″) cable class, allowing for high-quality terminations on flexible RG58, heat-resistant RG142, and high-efficiency LMR195/LMR200 cables used in wireless infrastructure.
This connector utilizes a professional crimp termination system. The outer ferrule provides a 360-degree mechanical bond with the cable’s shielding, while the internal socket is precision-machined to ensure a secure electrical path when mating with RP-TNC female ports. Manufactured with a heavy-duty nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent performance up to 11 GHz. The threaded interface ensures the connection remains stable in high-vibration environments, making it superior to bayonet-style connectors for industrial and outdoor wireless deployments.
