Coaxial cable Rangeful HF240 50 Ohm TNC male to SMA male, 0.5 m

Rangeful HF240 is a 50 Ohm coaxial cable with a TNC male connector on one end and an SMA male connector on the other, measuring 0.5 m in length. It is intended for RF signal transmission between equipment featuring TNC and SMA interfaces and is designed to preserve impedance matching for reliable, low-loss connections in short interconnect applications such as test benches, wireless equipment setups, antenna feeders and laboratory use.

Advantages

The cable combines a compact 0.5 m length with flexible construction to facilitate neat routing in confined environments. Its 50 Ohm characteristic impedance and matched TNC-to-SMA terminations reduce reflections and maintain signal integrity across relevant RF frequency ranges. The metal connector housings provide mechanical durability and screening continuity for stable performance during repeated connections and bench use.

Suitable for

• Connecting test instruments and RF modules with TNC and SMA interfaces
• Short RF links in wireless equipment and prototypes
• Antenna feedlines for measurement and calibration setups
• Laboratory and bench-top RF experiments where compact cabling is required

Key specifications

• Characteristic impedance: 50 Ohm
• Connector A: TNC male
• Connector B: SMA male
• Length: 0.5 m
• Cable type: flexible coaxial for short interconnects
• Typical use: RF signal transmission and test connections

How to use

Align the TNC male and SMA male connectors with the corresponding female ports on your devices and push/rotate as required to seat the connectors fully. Avoid forcing connectors at an angle to prevent damage to the mating threads and center contacts. Use the 0.5 m cable for short-distance connections on a bench, inside equipment racks, or between adjacent modules. When disconnecting, hold the connector body and unscrew or pull straight out to avoid stressing the cable jacket or inner conductor.

Usage recommendations

For optimal performance, keep cable runs as short and straight as practical, avoid sharp bends with radii smaller than the cable construction allows, and ensure connectors are clean and free of debris before mating. Store the cable coiled without tight loops and avoid excessive twisting; inspect connectors periodically for wear if used frequently in test environments.
