CONOTECH NS-14 F-Type Female to Female Barrel Coupler Adapter

With a shielding effectiveness exceeding 90 dB and a frequency range up to 3 GHz, this F-type barrel coupler ensures your satellite, cable TV, or antenna signals remain clean and strong. The nickel-plated brass body and PTFE insulator deliver low insertion loss under 0.5 dB, making it a reliable link for RG6 and RG59 coaxial runs.

Overview

The CONOTECH NS-14 is a straight F-type female-to-female coupler designed to join two coaxial cables with F connectors. Its 75-ohm impedance matches standard video and data distribution systems, while the durable construction supports up to 500 mating cycles. Operating from -20°C to +60°C, it suits indoor and protected outdoor installations.
