Coaxial cable Rangeful HF240 12 m, BNC male to BNC male

Rangeful HF240 coaxial cable, 12 m long, with BNC male connectors at both ends is designed to provide a shielded, fixed-length connection for analog RF and composite video signals. The cable is intended for linking BNC-compatible equipment such as radio transceivers, test and measurement instruments, CCTV cameras, and video monitors. Its 12-metre length offers a mid-range reach for installations where a reliable, low-interference connection is required.

Advantages

The HF240 cable delivers a consistent impedance and shielding to minimise signal loss and external interference over a 12 m run. BNC male-to-male termination enables quick push-and-twist coupling with standard BNC sockets without adapters. Its construction balances flexibility for routing in installations with sufficient mechanical durability for repeated handling and connection cycles. The fixed length removes the need for on-site assembly or additional connectors.

Suitable for

• Connecting CCTV cameras to DVRs or monitors
• Linking radio equipment and RF test instruments
• Signal routing between video sources and displays in AV setups
• Temporary or semi-permanent installations requiring a 12 m BNC-to-BNC lead

Key specifications

• Cable type: coaxial
• Connector type: BNC male to BNC male
• Length: 12 metres
• Intended signals: analog RF and composite video
• Shielding: braided/foil shield construction for reduced interference
• Typical impedance: 75 Ω (suitable for video) or 50 Ω variants depending on HF240 family standards — verify device compatibility before use
• Outer jacket: flexible PVC for indoor routing

How to use

Ensure both devices have BNC female sockets and are powered off before connecting. Align the BNC male connector with the socket, insert and twist until the connector locks. Route the cable to avoid sharp bends and sources of strong electromagnetic interference. For video or RF measurements, connect the cable between the signal source and the receiving device, then power on equipment and verify signal integrity. If using long runs through walls or conduits, leave gentle service loops to reduce strain on connectors.

Usage recommendations

Use the Rangeful HF240 cable in indoor environments and avoid exposure to prolonged moisture or direct sunlight. Match the cable impedance to the equipment (typically 75 Ω for composite video, 50 Ω for many RF applications) to prevent reflections and signal degradation. When higher attenuation or extended distance is an issue, consider using a lower-loss cable, an amplifier, or a different cable length suited to system requirements.
