Coaxial cable Rangeful TNC Male–TNC Male HF400 50 Ω 25 m

Rangeful HF400 coaxial cable with TNC male connectors at both ends is a 25 m, 50 Ω RF cable designed for transmitting radio-frequency signals with minimized loss. The cable uses HF400 construction for flexibility and reduced attenuation over long runs, while the threaded TNC male–TNC male connections offer mechanical stability and consistent electrical contact for lab setups, antenna feeds and test instrumentation.

Advantages

The HF400 dielectric and braided shield provide a balance between flexibility and shielding effectiveness, helping maintain signal integrity across the 25 m length. TNC male threaded connectors ensure a secure, low-reflection connection in environments where vibration or movement might otherwise loosen push-fit connectors. The 50 Ω impedance matches standard RF test equipment and many antenna systems, reducing mismatches and standing wave ratio (SWR) issues when used within its frequency range.

Suitable for

• RF test benches and laboratory measurements
• Antenna connections for routers, modems and external antenna systems
• Linking RF instruments such as spectrum analyzers and signal generators
• Field installations requiring a flexible, shielded 50 Ω cable

Key specifications

• Cable type: HF400 flexible coaxial cable
• Connector types: TNC male on both ends (threaded coupling)
• Impedance: 50 Ω
• Length: 25 m
• Construction: dielectric core with braided shield for RF shielding and mechanical flexibility

How to use

Connect each TNC male connector to the corresponding TNC female port on your device, ensuring the threads are engaged and tightened by hand until secure; avoid excessive force to prevent damage to the connector. Route the cable to minimize sharp bends and kinks—maintain bend radii recommended for HF400-type cables to preserve electrical characteristics. For test setups, verify connector seating and check signal levels with appropriate measurement equipment before critical measurements.

Usage recommendations

Store the cable coiled without tight loops and protect connector ends with caps when not in use. Avoid exposure to prolonged UV or chemical agents that can degrade the jacket. For best performance, use within the cable’s intended frequency range and periodically inspect connectors for corrosion or wear in field deployments.
