Coaxial cable Rangeful HF240 SMA male to RP‑TNC male, 2 m, low-loss RF jumper

Rangeful HF240 coaxial cable SMA male to RP‑TNC male, 2 m is a flexible low-loss RF jumper designed for reliable signal transfer between devices with SMA and RP‑TNC interfaces. Its construction focuses on shielding effectiveness and mechanical flexibility to maintain stable RF performance in antenna, radio and test setups. The 2 m length balances reach and signal integrity for typical bench, field and mounted installations.

Advantages

The cable offers low insertion loss and consistent impedance to minimise signal degradation across the supported frequency range. Robust connector terminations—SMA male on one end and RP‑TNC male on the other—ensure secure mating with corresponding ports. Its flexible jacket and durable inner conductor maintain performance under bending and routine handling while the shielding reduces electromagnetic interference for clearer RF transmission.

Suitable for

• Connecting antennas to routers, modems and access points with SMA or RP‑TNC ports
• Linking RF test equipment, signal generators and spectrum analyzers in bench setups
• Integrating radios, transceivers and IoT gateways during development and field deployment
• Temporary or semi-permanent installations requiring a 2 m jumper with low loss

Key specifications

• Length: 2 m
• Characteristic impedance: 50 Ω
• Shielding: multi-layer braid and foil for reduced EMI
• Jacket: flexible insulating material suitable for indoor and light field use
• Typical application: RF jumper for antennas, radios and test equipment

How to use

Verify that device ports accept SMA male and RP‑TNC male connectors before connecting. Align each connector carefully and engage threads or mating features without applying excessive torque; tighten by hand and, if required, use a torque wrench to the manufacturer's recommended specification for the connectors to avoid damage. Route the cable to avoid sharp bends, pinch points and sources of strong interference. For test or measurement setups, keep the cable length and routing consistent to maintain repeatable results.

Usage recommendations

Store the cable coiled without tight loops and protect connector ends with caps when not in use. For outdoor or permanent installations, consider additional environmental protection such as conduit or weatherproofing; avoid exposing the cable to prolonged UV, moisture or mechanical abrasion. Inspect connectors periodically for corrosion or wear and replace the cable if shielding or connectors show damage that could affect RF performance.
