Coaxial cable Rangeful HF240 TNC male to SMA male 50 Ω, 2 m

Coaxial cable Rangeful HF240 TNC male to SMA male 50 Ω, 2 m is a 2-metre RF connection cable designed to link devices with TNC and SMA ports while maintaining a standardized 50 ohm impedance. The cable uses RF-grade dielectric and shielding materials to support stable signal transfer for antennas, measuring instruments and radio systems. Its TNC male and SMA male terminations provide threaded, secure connections for equipment that requires compact RF interfaces and reliable electrical contact.

Advantages

The HF240 cable offers consistent 50 Ω impedance over its length to reduce signal reflection and ensure predictable RF performance. Threaded TNC and SMA male connectors deliver mechanical stability and maintain low contact resistance through repeated mating cycles. The 2 m length provides flexibility in arranging test setups or antenna placements without excessive signal loss typical of longer leads. The cable construction combines shielding and dielectric properties aimed at minimizing external interference and preserving signal integrity across the intended RF frequency range.

Suitable for

• Connecting antennas to radio transceivers or receivers
• Interfacing test and measurement equipment with TNC and SMA ports
• Linking RF modules and prototyping boards during development
• Temporary or semi-permanent installations in communications racks and benches

Key specifications

• Impedance: 50 Ω
• Length: 2 m
• Connector type (ends): TNC male to SMA male
• Cable category: coaxial RF cable designed for low-loss signal transfer
• Typical use: RF signal transmission for antennas, radio systems and test equipment

How to use

Connect the TNC male end to the device with a matching TNC female port and the SMA male end to the device or antenna with an SMA female port. Ensure threads are aligned and hand-tighten the connectors until firm; avoid over-tightening with tools to prevent damage to connector interfaces. Route the cable to avoid sharp bends, kinks and locations close to large sources of electromagnetic interference. For test setups, label each end if multiple cables are used to simplify reconnection and troubleshooting.

Usage recommendations

Use the cable within its intended frequency and power limits, avoid stretching or crushing the cable, and store coiled without tight loops. Inspect connectors periodically for dirt or wear and clean with appropriate contact cleaner if necessary. For installations requiring long-term outdoor exposure or elevated mechanical strain, consider weatherproofing or using a cable with specialized jacketing.
