Coaxial cable Rangeful SMA Male to SMA Female HF240 3 m pure copper

Rangeful HF240 coaxial cable with SMA male to SMA female connectors is a 3-meter pure copper RF cable designed for reliable signal transmission between devices with SMA interfaces. The cable combines flexibility and low-loss conductor properties to maintain signal integrity over short-range connections, making it suitable for test setups, antenna extensions and RF modules. Its straight SMA male to straight SMA female configuration allows simple, tool-free coupling between routers, radios, measurement equipment and antennas that use standard SMA ports.

Advantages

The pure copper conductor provides consistent electrical conductivity and reduced attenuation for improved RF performance across common VHF/UHF frequency ranges used in wireless communications and testing. The 3 m length gives greater placement freedom while the HF240 cable construction balances flexibility with mechanical durability to withstand typical handling without compromising connection quality. Standard SMA male and SMA female terminations ensure compatibility with a wide range of consumer and laboratory RF devices.

Suitable for

• Connecting antennas to routers, modems or RF front-ends
• Linking radio modules and transceivers in prototyping or development
• Test bench connections between measurement equipment and DUTs
• Short-range signal routing in wireless setups and repeater stations

Key specifications

• Cable type: HF240 coaxial
• Conductor material: pure copper
• Connector A: SMA male
• Connector B: SMA female
• Length: 3 m
• Construction: flexible jacket suitable for indoor routing

How to use

Align the SMA male connector with the corresponding SMA female thread and engage by hand, turning clockwise until finger-tight. Avoid using pliers or excessive torque which can damage the connector or mating port. Route the cable to minimize sharp bends; maintain a gentle bend radius throughout its length to preserve electrical characteristics. For temporary test connections, ensure both ends are clean and free of debris before mating to reduce signal loss.

Usage recommendations

For best RF performance, keep cable runs as short as practical, avoid kinking, and prevent sustained stress on connector joints. If used in a laboratory environment, inspect connector interfaces periodically for wear and ensure correct torque when reconnecting. Store coiled without tight loops to preserve flexibility and shielding integrity.
