Coaxial cable Rangeful BNC male to SMA male RG58/U 50 Ω 2 m

Rangeful coaxial cable BNC male to SMA male RG58/U 50 Ω 2 m is a 2-metre RF interconnect designed to link equipment with BNC and SMA ports while preserving a 50-ohm characteristic impedance. Constructed with RG58/U coaxial geometry, it supports standard laboratory, test and radio-frequency applications where impedance matching and consistent signal transfer are required. The cable assembly provides a compact connection between test instruments, transceivers and antenna feeds with common BNC-to-SMA termination.

Advantages

This BNC male to SMA male cable offers consistent 50 Ω impedance to minimize reflections and preserve signal integrity across its length. The RG58/U construction balances flexibility and shielding performance for easy routing in test benches and equipment racks. Factory-terminated connectors provide reliable mechanical fit and repeatable electrical contact between devices with BNC and SMA interfaces.

Suitable for

• Connecting test equipment such as oscilloscopes, signal generators and spectrum analyzers to devices with BNC or SMA ports
• Linking radio transceivers, receivers and SDR units to external antennas or preselectors
• Laboratory setups and bench testing where short, reliable RF interconnects are required
• Temporary or permanent connections in communications racks and measurement systems

Key specifications

• Impedance: 50 Ω
• Cable type: RG58/U coaxial construction
• Connector A: BNC male
• Connector B: SMA male
• Length: 2 m
• Typical usage: RF signal transmission, testing and measurement interconnects

How to use

Align the BNC male connector with the BNC female receptacle and push then twist to secure the bayonet locking. Align the SMA male with the SMA female and hand-tighten the threaded coupling until snug; avoid over-tightening to prevent damage to the connector threads. Route the cable to avoid sharp bends and mechanical strain at the connector junctions. For measurement accuracy, allow connectors to seat fully and ensure mating interfaces are clean and free of debris before use.

Usage recommendations

For best RF performance, keep cable runs as short as practical, avoid tight bending radii, and periodically inspect connectors for wear or contamination. Use this RG58/U 50 Ω assembly where matching to 50-ohm equipment is required; avoid using it in systems specified for other impedances. When installing in permanent setups, secure the cable to prevent repeated flexing at connector ends.
