Coaxial cable Rangeful SMA male to SMA male RG58/U 50Ω 15 m

The Rangeful coaxial cable SMA male to SMA male RG58/U 50Ω 15 m is a flexible RF transmission line designed for connecting antennas, test instruments and radio equipment over short to medium distances. Constructed with RG58/U dielectric and a 50 ohm characteristic impedance, this 15 metre cable features SMA male terminations on both ends, providing compact threaded connections suitable for many amateur radio, measurement and wireless applications.

Advantages

This cable combines the common RG58/U construction with SMA male connectors to deliver consistent 50 Ω impedance, reliable shielding against external interference and convenient screw-on coupling. The 15 m length allows placement flexibility while remaining manageable for installations and field use. Its flexibility eases routing in confined spaces and equipment racks without significant signal degradation for typical VHF/UHF and lower microwave frequencies where RG58 performance is appropriate.

Suitable for

• Connecting handheld transceivers, routers or modems to external antennas
• Linking test equipment such as spectrum analyzers and signal generators to measurement points
• Amateur radio station setups and temporary field deployments
• Laboratory and educational RF experiments requiring SMA terminations

Key specifications

• Cable type: RG58/U
• Connector type: SMA male — SMA male on both ends
• Impedance: 50 Ω
• Length: 15 m
• Construction: coaxial with braided shielding and dielectric suitable for RG58/U
• Typical frequency range: suitable for VHF, UHF and certain microwave applications where RG58 is appropriate

How to use

Connect one SMA male end to the equipment or antenna port and tighten the SMA coupling nut by hand until snug; avoid overtightening to prevent connector damage. Route the cable to minimize sharp bends and avoid running alongside strong power cables to reduce potential interference. If the cable is used in testing setups, secure connectors and verify continuity and return loss with appropriate test equipment before critical measurements.

Usage recommendations

Use the cable within its mechanical and frequency limitations: avoid excessive bending radii and prolonged exposure to harsh outdoor conditions unless additional weatherproofing is applied. For applications requiring lower loss at higher microwave frequencies or permanent outdoor installations, consider higher-specification coaxial types. Periodically inspect connectors for wear and ensure SMA threads are clean for reliable connections.
