Coaxial cable Rangeful RP-SMA Male to RP-SMA Male HF240 12 m

Rangeful HF240 coaxial cable with RP-SMA male connectors on both ends is a fixed-length 12 m RF cable intended for connections that require reverse-polarity SMA termination. The cable is built for linking radios, Wi‑Fi equipment, antenna systems and other RF devices where a reliable 12 meter run is needed. It provides a simple, pre-terminated solution for extending antenna placement, setting up test configurations, or installing permanent connections without the need for field crimping or adapter assemblies.

Advantages

The cable offers a fixed 12 m length that simplifies planning and deployment of antenna and RF layouts. With RP-SMA male connectors at both ends, it matches devices that use reverse-polarity SMA terminations and avoids the need for additional gender changers. The HF240 coaxial construction balances flexibility and signal integrity for typical Wi‑Fi and short-range RF use, and the factory-installed connectors ensure consistent mechanical fit and electrical contact compared with improvised terminations.

Suitable for

• Extending Wi‑Fi or router antennas to improve placement
• Connecting radio transceivers and external antennas in test setups
• Fixed installations where a 12 m pre-terminated coaxial run is required
• Laboratory and prototyping environments that require reliable RP-SMA terminations

Key specifications

• Length: 12 meters
• Connector type: RP-SMA male at both ends (reverse-polarity SMA)
• Cable type: HF240 coaxial
• Intended use: RF and antenna connections for Wi‑Fi, radios and similar devices
• Construction: factory-terminated, flexible coaxial assembly

How to use

Confirm that both devices use RP-SMA male terminations or compatible reverse-polarity SMA ports before connecting. Align the connector threads carefully and hand-tighten until snug; avoid using excessive torque or tools that can deform the connector. Route the cable to avoid sharp bends, tight kinks, and sources of mechanical stress. For outdoor or permanent installations, ensure the cable and connectors are protected from weather exposure using appropriate sealing methods and strain relief to preserve performance over time.

Usage recommendations

For best RF performance, keep connector interfaces clean and free from debris, avoid tight bending radii near the ends, and use weatherproofing and strain relief for external runs. If your equipment uses standard SMA rather than RP-SMA, use the correctly gendered adapters or an alternative cable with matching connectors to prevent incompatible mating.
