Description
The BNC Female Reverse Polarity (RP-BNC) connector is a specialized variation of the standard BNC jack, widely utilized in wireless communications to prevent the connection of unauthorized high-gain antennas. While the outer housing retains the standard BNC female bayonet interface, the Reverse Polarity design swaps the internal contact: this “female” jack features a protruding male pin instead of a socket. It is optimized for the 2.5mm to 3mm cable class, ensuring a perfect fit for high-performance LMR100, flexible RG174, and high-temperature RG316.
This connector utilizes a hex-crimp termination system for the outer conductor, providing a high-strength 360-degree mechanical bond and superior strain relief for flexible coaxial lines. The industry-standard bayonet interface allows for rapid, tool-less mating with RP-BNC male plugs. Manufactured with a durable nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and reliable signal integrity across the microwave spectrum, specifically in WLAN and broadband applications.
