Coaxial BNC to BNC Cable 20m — No name, model CROSS-COMBO/20M, black

Coaxial BNC to BNC Cable 20m — No name, model CROSS-COMBO/20M, black is a 20-meter coaxial cable with standard BNC male connectors on both ends, designed for transmission of analogue and digital video signals. The cable is intended for use in CCTV and monitoring systems, laboratory setups and any application that requires a reliable BNC-to-BNC connection over medium distances. Its black outer sheath provides basic protection and visual discreteness for installations in walls, ceilings or along cable trays.

Advantages

The cable offers a straightforward, plug-and-play BNC to BNC connection compatible with most video and test equipment featuring BNC ports. With its 20 m length it covers medium-distance runs without the need for additional splices or couplers in many typical surveillance and AV setups. The single-shielded coax construction and standard impedance are suitable for stable video and signal transmission, while the black jacket reduces visibility in professional and domestic installations.

Suitable for

• CCTV camera connections and analog or HD-analogue surveillance systems
• Connecting BNC-equipped monitors, DVRs, video recorders and encoders
• Signal routing between test instruments and measurement equipment
• Temporary or permanent AV installations where a 20 m BNC link is required

Key specifications

• Cable type: coaxial with BNC male connector on both ends
• Length: 20 meters
• Colour: black outer jacket
• Intended signals: analogue and digital video, composite video, test signals
• Typical use: CCTV, monitoring, AV and test equipment connections

How to use

Connect each BNC male connector to the corresponding BNC female port on devices such as cameras, DVRs, monitors or test instruments by aligning the bayonet and twisting until it locks. Route the cable along the chosen path and secure it with appropriate cable clips or ties, avoiding sharp bends and excessive tension. For wall or ceiling installations, ensure the cable is fixed at regular intervals to prevent sagging and to maintain signal integrity over the 20 m run.

Usage recommendations

For reliable video performance, keep the cable away from strong sources of electromagnetic interference such as power lines and large motors. Use appropriate grounding and, where signal quality over longer distances is critical, consider signal amplification or switching to higher-specification coax or balanced transmission solutions.
