Coaxial cable Rangeful HF240 SMA male to RP‑TNC male, 3 m

Rangeful HF240 is a 3 m coaxial cable with an SMA male connector on one end and an RP‑TNC male connector on the other. Designed for RF signal transmission, this jumper cable provides a reliable connection between devices with differing connector types while preserving flexibility and stable electrical contact. The 3‑metre length allows placement of antennas, routers or test instruments at a distance from equipment without compromising signal continuity.

Advantages

The cable combines two common RF connector types to enable interoperable links between antennas, modems and measurement devices. Its construction focuses on low signal loss for short‑range RF connections and consistent impedance matching across the cable length. The flexible jacket and strain‑relief at the connector interfaces reduce mechanical stress during installation and repositioning.

Suitable for

• Connecting external antennas to routers or gateways with different connector standards
• Interfacing test equipment and measurement devices in RF laboratories or field testing
• Extending antenna placement for improved reception in indoor or outdoor installations
• Temporary or semi‑permanent links between SMA and RP‑TNC equipped devices

Key specifications

• Cable type: coaxial jumper cable
• Length: 3 m
• Connector A: SMA male
• Connector B: RP‑TNC male (reverse polarity TNC male)
• Typical impedance: 50 Ω
• Primary use: RF signal transmission for antennas, routers and test gear
• Jacket: flexible outer sheath for routing and repositioning

How to use

Ensure both connectors on the devices are free of debris and align the SMA male and RP‑TNC male connectors with their corresponding ports before mating. Gently hand‑thread the SMA onto the mating connector until finger‑tight and then secure the RP‑TNC male by rotating until it engages; avoid over‑torquing to prevent damage to the connector threads. Route the cable to avoid sharp bends and tension; use cable ties or clips as needed to secure it during operation. For test setups, verify continuity and expected signal levels after installation.

Usage recommendations

Use this cable in applications within the frequency and power limits of typical 50 Ω RF jumper cables. Avoid exposure to excessive moisture and mechanical stress; store coiled without tight loops to preserve cable integrity. When connecting equipment outdoors, protect connector interfaces with suitable caps or weatherproofing to maintain performance over time.
