BNC Female-to-Female Coupler 100pcs, 75 CCTV Coaxial Cable Connector

Connect and extend your CCTV video cables with ease using the BNC Female to Female Coupler. This barrel adapter joins two BNC male connectors, allowing you to lengthen or repair video transmission lines without soldering or special tools. Built with a zinc alloy housing and gold-plated copper contacts, it ensures stable signal transfer (75 ohm impedance) with minimal loss. Rated for over 1000 mating cycles and resistant to corrosion, it's ideal for security camera systems, DVRs, analog monitors, and network video transmission equipment.

Features:
- Female to Female - Simple Cable Extension - Need to join two BNC cables? This coupler connects two male-ended BNC cables directly. No crimping, no soldering, no tools. Just screw or push and twist (depending on connector type) - perfect for lengthening security camera runs or repairing damaged cable ends.
- 75 Ohm Impedance - Optimised for Video - Not all BNC couplers are made equal. This adapter is impedance-matched at 75 ohms, the standard for analogue video (CCTV, SDI, composite video). Maintains signal integrity and reduces reflection and loss over extended cable runs.
Gold-Plated Copper Contacts - Anti-Corrosion - Cheap connectors tarnish and lose signal over time. The inner contacts are gold-plated over copper, providing excellent conductivity, resistance to oxidation, and long-term reliability. Ensures a clean, noise-free connection even in humid or outdoor environments (when housed in weatherproof boxes).
- Zinc Alloy Housing - Durable & Shielded - Plastic couplers crack; cheap metal ones corrode. This BNC coupler features a zinc alloy shell that is structurally rigid, resists impact, and provides effective electromagnetic shielding. The alloy also resists rust, making it suitable for long-term installation.
- Up to 1000 Mating Cycles - Built to Last - Frequently disconnecting and reconnecting cables can wear out inferior connectors. Rated for over 1000 insertion/removal cycles, this coupler withstands regular maintenance, camera swaps, and testing without losing grip or signal quality.
- Wide Application - CCTV, DVR, Monitors - Works with any BNC-based video system. Perfect for: security cameras (analog HD-TVI, CVI, AHD, CVBS), DVR input/output ports, video baluns, test monitors, matrix switches, and video capture cards. Also suitable for some RF or instrumentation applications within 0-2 GHz range.
