Coaxial cable Rangeful HF400 SMA Male to SMA Female, 30 m, full copper, 50 Ω

Rangeful HF400 coaxial cable with SMA male to SMA female connectors, 30 m length and full copper conductor provides a 50 Ω transmission line for RF signal and antenna connections. The cable is designed for a balance of flexibility and mechanical durability to support installations where a long, low-loss connection is required. It is appropriate for external and indoor routing with attention to bend radius and connector integrity.

Advantages

The HF400 cable features a full copper center conductor and consistent 50 Ω impedance to reduce insertion loss and maintain signal integrity across the 30 m length. SMA male to SMA female connector coupling ensures a defined threaded connection for stable mating. Construction emphasizes flexibility to ease installation while providing sufficient shielding to limit external interference and preserve RF performance.

Suitable for

• Ham radio stations and amateur transceivers
• Wi‑Fi and wireless access point antenna extensions
• LTE/4G/5G antenna connections and signal routing
• Laboratory test equipment and RF measurement setups
• Longer cable runs between radio units and outdoor antennas

Key specifications

• Characteristic impedance: 50 ohm
• Length: 30 meters
• Center conductor: full copper
• Connector type: SMA male to SMA female (threaded)
• Cable model: HF400-type coaxial construction
• Typical use: RF signal transmission and antenna connection

How to use

Route the cable following recommended bend radius to avoid kinking; terminate connections by hand-tightening the SMA coupling nut and then apply a light quarter-turn with a suitable torque tool if required by the equipment manufacturer. Avoid sharp bends, excessive pulling force, and contact with sharp edges. For outdoor runs, ensure connectors are protected from moisture with appropriate sealing or weatherproofing materials. When connecting to sensitive test instruments, verify connector cleanliness and inspect for damage before use to maintain accurate measurements.

Usage recommendations

For optimal performance, keep cable runs as short as practical, use proper strain relief near connectors, and protect exposed connectors from moisture and debris. Inspect the SMA interfaces periodically and replace the cable if you observe excessive wear, corrosion, or significant changes in signal level during operation.
