Coaxial cable Rangeful HF240 BNC male to SMA male 50 Ω, 7 m

Rangeful HF240 is a 7 m coaxial cable with a BNC male connector on one end and an SMA male connector on the other, designed for 50 Ω RF signal transmission. The cable provides impedance-matched connectivity between devices with BNC and SMA ports and is intended for use with test equipment, antennas and communication devices where a flexible, shielded cable of this length is required.

Advantages

The HF240 cable combines a standard 50 ohm impedance with professionally terminated BNC male and SMA male connectors to ensure consistent signal transfer and minimal reflections. Its 7 m length enables flexible placement of equipment while maintaining a single continuous connection, and the coaxial shielding reduces external interference. The cable’s construction supports stable RF performance across typical frequency ranges for general-purpose test and communication use.

Suitable for

• Connecting test instruments (spectrum analyzers, signal generators) to devices with BNC or SMA ports
• Linking antennas to radio equipment when a BNC-to-SMA connection is needed
• Temporary setups and bench testing where a 7 m cable run is required
• General RF signal routing in amateur radio and communication systems

Key specifications

• Impedance: 50 Ω
• Length: 7 m
• Connector A: BNC male
• Connector B: SMA male
• Cable type: Coaxial, shielded
• Typical application: RF signal transmission between BNC and SMA ports

How to use

Inspect both connectors and the cable for visible damage before use. Firmly push the BNC male connector onto the corresponding BNC female socket and twist the SMA male connector clockwise onto the SMA female thread until hand-tight; do not overtighten with tools to avoid damaging the SMA thread. Ensure both connected devices share compatible impedance and proper grounding. Route the cable to avoid sharp bends, kinks or heavy compression that could degrade performance.

Usage recommendations

Store the cable coiled without tight loops and protect connectors with caps when not connected. For best RF performance, avoid running the cable parallel to power lines or other strong interference sources and replace the cable if the shielding or connector integrity becomes compromised.
