Coaxial cable Rangeful HF240 TNC male to SMA male 50 Ω, 10 m

Rangeful HF240 coaxial cable with TNC male to SMA male connectors is a 10 m, 50 Ω RF cable intended for signal connections between devices with TNC and SMA ports. The cable provides a defined 50-ohm transmission path to minimize impedance mismatch in short- to medium-range installations such as test setups, antennas, routers and radio equipment. The HF240 construction balances flexibility and shielding to maintain signal integrity across the intended frequency range.

Advantages

The cable combines a reliable 50 Ω impedance with industry-standard TNC and SMA male connectors for compatibility with a wide range of RF equipment. Its 10 m length allows flexible placement of devices without the need for immediate relocation, while the conductor, dielectric and shielding are designed to reduce loss and external interference in typical test and field environments. The assembly is suitable for repeated connections and straightforward integration into measurement rigs or antenna systems.

Suitable for

• Connecting test instruments and RF analyzers with TNC and SMA interfaces
• Linking antennas to routers, modems or radio transceivers
• Temporary or semi-permanent lab and field measurement setups
• Extending RF connection runs where 50 Ω characteristic impedance is required

Key specifications

• Impedance: 50 Ω
• Connector A: TNC male
• Connector B: SMA male
• Length: 10 m
• Cable type: coaxial (flexible RF cable)
• Typical use: RF signal transmission for short- to medium-range connections

How to use

Before connecting, verify that both devices accept 50 Ω loads and that their ports match the TNC and SMA male terminations. Align the TNC and SMA connectors with the device ports and carefully screw each connector until seated to ensure good mechanical and electrical contact; avoid over-tightening. Route the cable to minimize sharp bends and keep it away from strong sources of electromagnetic interference. For measurements, use consistent connector torque and grounding practices to maintain repeatability.

Usage recommendations

For optimal performance, avoid kinking the cable and maintain bend radii consistent with flexible coaxial installation practices. If used in measurement or calibration work, periodically inspect connectors for wear and clean mating surfaces with appropriate contact cleaners. When deploying outdoors or in harsh environments, use additional weatherproofing or conduit as required to protect the cable and connectors.
