## Summary description

This Rangeful HF400-SM-PL-3 coaxial cable connects an SMA male plug to a PL259 UHF connector. It is 3 meters long, constructed with full copper conductors and matched to 50 ohm impedance for HF/VHF/UHF radio use. Suitable for amateur radio, transceivers, and antenna connections where low-loss, durable 50 Ω cabling is required.

## Long description

The Rangeful HF400-SM-PL-3 is a 3 meter coaxial cable with an SMA male connector on one end and a PL259 UHF (SO-239) compatible connector on the other. Built with full copper conductors and a 50 Ω characteristic impedance, this cable is intended for HF, VHF and UHF radio connections where reliable signal transfer and mechanical durability are required. The construction balances flexibility and shielding to support transceivers, amateur radio equipment and antenna feedlines in typical portable and fixed installations.
Advantages
The cable features full copper inner conductor and braid for consistent conductivity and lower attenuation compared with plated alternatives. Its 50 Ω impedance matches common radio equipment, reducing reflections and maintaining signal integrity across HF through UHF bands. The SMA male to PL259 configuration provides compatibility between modern equipment with SMA interfaces and legacy or field-deployable equipment using UHF connectors. The 3 m length offers a practical reach for base and portable setups without excessive signal loss.
Suitable for
Connecting transceivers to antennas and antenna tuners
Linking SDRs, handheld radios or modems with different connector types
Temporary field deployments and portable operations
Laboratory testing of HF/VHF/UHF radio equipment
Key specifications
Length: 3 meters
Characteristic impedance: 50 Ω
Inner conductor material: full copper
Outer conductor: copper braid
Connector A: SMA male
Connector B: PL259 UHF (compatible with SO-239)
Frequency range: suitable for HF, VHF and UHF applications
Cable type: low-loss RF coaxial for radio use
How to use
Ensure both connectors and mating ports are clean and free of debris before making connections. Align the SMA male pin with the SMA female socket and gently screw until hand-tight; avoid over-tightening which can damage threads. For the PL259 end, align the center pin and thread the connector onto the SO-239 receptacle, securing it firmly but without excessive force. Route the cable to minimize sharp bends and avoid kinks; maintain bend radius appropriate for RF coax to prevent impedance changes. When used outdoors, protect connectors from moisture with appropriate sealing or tape.
Usage recommendations
For best performance, keep cable runs as short as practical and avoid coiling excess cable tightly. Inspect connectors periodically for corrosion or wear, especially after field use. Use compatible grounding and lightning protection measures when connecting outdoor antennas.
