Antenna cable Rangeful RP-SMA to RP-SMA HF240 15 m pure copper

Rangeful RP-SMA to RP-SMA HF240 15 m pure copper antenna cable is a 15-metre coaxial cable with RP-SMA male connectors at both ends and a solid pure copper conductor. It is built for RF signal transmission between devices that use RP-SMA interfaces, such as routers, external antennas, wireless modems and signal boosters. The HF240 construction balances flexibility and shielding to keep insertion loss low over the specified length while remaining easy to route in home or professional installations.

Advantages

The cable uses a pure copper central conductor that improves conductivity and reduces resistive losses compared with copper-clad alternatives. RP-SMA male-to-male connectors provide a secure, threaded connection that resists vibration and accidental disconnection. The HF240 coaxial design offers consistent impedance and shielding to minimise interference and maintain signal integrity across the 15 m run. The outer sheath and flexible dielectric allow for straightforward installation without sharp bends that could degrade performance.

Suitable for

• Connecting routers to external RP-SMA antennas
• Linking wireless modems or access points to signal amplifiers
• Extending antenna placement for better reception in home or office
• Temporary or permanent installations where a 15 m cable run is required

Key specifications

• Cable type: coaxial HF240
• Length: 15 m
• Conductor material: pure copper central conductor
• Connector type: RP-SMA male to RP-SMA male
• Characteristic impedance: 50 Ω
• Frequency range: suitable for common Wi‑Fi and cellular antenna frequencies (RF applications)
• Construction: flexible dielectric and outer jacket for easy routing

How to use

Place the cable so it follows a smooth path between the two RP-SMA equipped devices, avoiding tight bends or kinks. Align the threaded RP-SMA connectors with the device terminals and rotate gently until hand-tight; do not over-tighten with tools to avoid damaging connector threads. Ensure connectors are clean and free of debris before making connections. If the run is installed outdoors or in exposed locations, use appropriate weatherproofing at the connector interfaces to protect against moisture.

Usage recommendations

For best performance, keep the cable away from large sources of electrical noise and avoid running it parallel to mains power lines for long distances. When routing through walls or conduits, allow extra length to prevent stress on connectors. Inspect connectors periodically for corrosion or wear, and replace the cable if shielding or conductor integrity is compromised.
