Coaxial cable Rangeful SMA Male to SMA Female HF400 50 Ω flexible 3 m

The Rangeful HF400 50 Ω flexible coaxial cable with SMA male to SMA female connectors is a 3 m RF interconnect designed for reliable signal transmission between antennas, radio equipment and test instruments. Constructed to balance flexibility and controlled impedance, this cable supports typical RF and antenna wiring where low loss and standard SMA terminations are required. The product is intended for use in lab setups, amateur radio installations, routers and signal testing applications that require a flexible, easy-to-route coaxial lead.

Advantages

This HF400 cable provides consistent 50 ohm impedance and stable SMA male to SMA female connections to minimize reflections at mating interfaces. The flexible dielectric and outer jacket allow easy routing in confined spaces while maintaining mechanical durability for repeated handling. The combination of low insertion loss for its class and standard SMA terminations simplifies integration with common RF equipment and test gear.

Suitable for

• Connecting antennas to routers, modems and RF modules
• Laboratory and bench testing of RF circuits and components
• Amateur radio and short-range communication setups
• Signal measurement and temporary or semi-permanent instrument connections

Key specifications

• Impedance: 50 Ω
• Connector 1: SMA male
• Connector 2: SMA female
• Cable type: HF400 coaxial (flexible)
• Length: 3 m
• Typical use: RF / antenna interconnect

How to use

Confirm that both devices accept SMA terminations and that a 50 ohm cable is appropriate for the equipment. Align the SMA male pin with the female socket and hand-tighten the coupling nut until snug; do not overtighten with excessive torque. Route the cable to avoid sharp bends or kinks and keep it away from sources of mechanical abrasion or strong electromagnetic interference. For test bench setups, secure the cable to reduce movement and maintain consistent measurement conditions.

Usage recommendations

For best performance, avoid bending the cable below its minimum bend radius and protect connector interfaces from contamination and impact. Use proper torque tools for repeatable connections in situations where consistent RF performance is critical. If used outdoors or in high-vibration environments, consider additional strain relief and environmental protection at the connector junctions.
