Description
The BNC Male Reverse Polarity (RP-BNC) connector is a variation of the standard BNC interface, commonly utilized in wireless networking to meet specific regulatory requirements. While the outer coupling nut retains the standard BNC male bayonet style, the Reverse Polarity configuration swaps the center conductor: this “male” plug features a female socket instead of a protruding pin. It is specialized for the 2.5mm to 3mm cable class, specifically optimized 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 mechanical bond and excellent strain relief for flexible coaxial lines. The two-stud bayonet locking system ensures a vibration-resistant mate that can be connected and disconnected rapidly without tools. Manufactured with a durable nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and reliable operation across the RF spectrum, ensuring signal integrity in sophisticated WLAN and broadband systems.
