Coaxial cable Rangeful SMA male to PL259 UHF, RG58/U, 50 Ω, 12 m

Rangeful 12 m coaxial cable with SMA male to PL259 (UHF) connectors is a flexible RG58/U 50 Ω lead for RF signal transmission. The cable provides a medium-length connection between devices with SMA and UHF (PL259) interfaces, maintaining characteristic impedance to support reliable radio-frequency performance in amateur radio, shortwave and testing setups.

Advantages

The RG58/U construction gives the cable good flexibility and manageable diameter for routing in compact installations. A 50 Ω impedance ensures compatibility with common RF equipment and minimizes standing wave ratio issues when used with matched systems. The SMA male connector offers a secure threaded coupling to SMA-female ports while the PL259 (UHF) connector provides a widely used connection for transceivers and test gear. The 12 meter length balances reach with acceptable insertion loss for medium-range interconnections.

Suitable for

• Amateur radio transceiver to antenna tuner or patch lead
• Shortwave receiver connections and listening setups
• Laboratory and equipment testing where SMA-to-UHF adaptation is required
• Temporary field deployments or bench setups needing flexible 50 Ω cabling

Key specifications

• Cable type: RG58/U coaxial
• Characteristic impedance: 50 Ω
• Length: 12 m
• Connector A: SMA male (threaded)
• Connector B: PL259 (UHF) male
• Core conductor: stranded (typical for RG58/U flexibility)
• Shielding: braided shield for RF protection
• Outer jacket: flexible PVC (standard for RG58/U)

How to use

Connect the SMA male end to the SMA-female port of your device, ensuring the threaded coupling is fully engaged without over-tightening. Attach the PL259 connector to the corresponding UHF (SO-239) socket by aligning and gently tightening the mating connector. Route the cable to avoid sharp bends and excessive strain, keeping separation from heavy electrical mains or large power supplies to reduce interference. Verify system matching and check for acceptable SWR or signal levels after installation.

Usage recommendations

For best performance, use this 50 Ω RG58/U cable in systems designed for 50 Ω impedance. Keep cable runs as short and straight as practical, avoid crushing or kinking the cable, and inspect connectors periodically for corrosion or loose mating. If low loss or higher frequency stability is required, consider using a lower-loss cable type for longer runs.
