Coaxial cable Rangeful BNC male to SMA male RG58/U 50 Ω, 3 m

Rangeful 3-meter coaxial cable with BNC male to SMA male connectors is built on RG58/U 50 Ω construction for RF signal transmission. The cable provides a flexible interconnect between measurement equipment, radio transceivers, antennas and other devices that require 50-ohm impedance matching. With standard BNC and SMA terminations and a three-metre length, the cable is suitable for lab setups, field tests and equipment connections where stable signal transfer is required.

Advantages

This RG58/U 50 Ω cable delivers reliable impedance matching and reduced reflections for RF paths. The BNC male to SMA male connector combination allows straightforward mating with common test instruments and small radio equipment. The 3 m length provides flexibility in equipment placement without excessive signal loss for short-range applications. The construction balances flexibility for routing with sufficient shielding to limit external interference in typical test and communication environments.

Suitable for

• Connecting test instruments (oscilloscopes, spectrum analyzers) to devices with BNC or SMA interfaces
• Linking radio transceivers and external antennas that use 50 Ω matching
• Laboratory and bench testing of RF circuits and prototypes
• Field measurements and temporary installations requiring a detachable RF lead

Key specifications

• Length: 3 m
• Connector A: BNC male
• Connector B: SMA male
• Typical use: RF signal transmission, measurements, antenna connections
• Construction: coaxial with shielded braid and dielectric suitable for RF

How to use

Inspect connectors and cable for visible damage before use. Ensure the BNC male and SMA male connectors are compatible with the mating ports on your equipment; align and push the BNC bayonet until it locks and carefully thread the SMA onto its threaded receptacle without cross-threading. Keep cable bends gentle and avoid sharp kinks to preserve impedance characteristics. For measurement tasks, connect the cable between the signal source or antenna and the instrument input, and confirm signal levels and return loss as required by your test procedure.

Usage recommendations

Use the cable in short-run RF connections where a 50 Ω impedance is required. Avoid prolonged exposure to extreme weather or mechanical stress; store coiled without tight loops. For critical measurements, verify connector torque and check for continuity and VSWR to ensure measurement accuracy.
