Coaxial cable Rangeful HF400 TNC male to SMA male, 50 Ω, flexible HF400, length 30 m

Coaxial cable Rangeful HF400 TNC male to SMA male, 50 Ω, flexible HF400, length 30 m provides a flexible RF connection between equipment with TNC and SMA interfaces. The cable is built on HF400 construction with 50 ohm characteristic impedance and a 30 m overall length, intended for signal routing between antennas, radio transceivers, test instruments and related RF devices. Connectors are TNC male on one end and SMA male on the other to match corresponding device ports.

Advantages

The cable combines a flexible HF400 dielectric and shielding structure with standardized 50 Ω impedance to minimise signal reflections and maintain consistent transmission characteristics over the run. The TNC male and SMA male terminations provide mechanical compatibility with a range of RF equipment while enabling a compact connection footprint. Its 30 m length allows remote placement of antennas or devices without intermediate adapters, and the flexible construction simplifies routing in confined or irregular installation paths.

Suitable for

• Connecting antennas to radio transceivers where TNC and SMA interfaces are used
• Routing RF signals between test instruments and devices in lab environments
• Temporary or semi-permanent installations requiring a 30 m coaxial link
• Signal distribution and interconnection in radio, telemetry, and wireless systems

Key specifications

• Characteristic impedance: 50 Ω
• Connector types: TNC male (one end), SMA male (other end)
• Cable type: HF400 flexible coaxial construction
• Length: 30 m
• Intended use: RF signal transmission between compatible TNC and SMA devices

How to use

Route the coaxial cable between the two devices ensuring connectors are aligned with the mating ports. Hand-tighten SMA and TNC connectors to the recommended torque where available; avoid excessive force to prevent damage to connector threads. Where the cable passes through tight spaces, guide it gently to avoid sharp bends; maintain bend radii consistent with flexible HF400 coaxial cable practice. Inspect connectors for cleanliness and secure seating before powering connected equipment.

Usage recommendations

For best performance, avoid kinking the cable, keep separation from high-voltage power runs, and minimise exposure to severe moisture or mechanical abrasion. When long-term outdoor deployment is required, use appropriate protective conduit or weatherproofing at connector interfaces. Verify connector compatibility and, if necessary, use adapters rated for 50 Ω systems to prevent impedance mismatches.
