Coaxial Cable Rangeful HF400-SM-PL-1 — SMA Male to PL259 UHF, Full Copper, 50 Ω, 1 m

Rangeful HF400-SM-PL-1 is a 1 m coaxial cable with an SMA male connector on one end and a PL259 (UHF) connector on the other, built with full copper conductors and a nominal impedance of 50 Ω. Intended for HF and radio frequency applications, this jumper cable offers a compact, low-loss connection between transceivers, radios and antennas where a short interconnect is required.

Advantages

The cable's full copper inner conductor and braid provide consistent conductivity and predictable RF performance across HF bands. Its SMA male to PL259 UHF connector combination enables compatibility with a wide range of amateur radio equipment and legacy devices that use UHF-type connectors. The 1 m length balances flexibility and minimal insertion loss for short runs, while the 50 Ω impedance maintains signal integrity in matched systems.

Suitable for

• Connecting HF transceivers to antennas or antenna tuners over short distances
• Temporary links during communications testing and setup
• Interfacing amateur radio equipment with UHF- and SMA-equipped devices
• Short jumpers in bench setups and field portable stations

Key specifications

• Length: 1 metre
• Connector A: SMA male
• Connector B: PL259 (UHF) male
• Conductor material: full copper (inner conductor and braid)
• Characteristic impedance: 50 Ω
• Intended use: HF and radio frequency signal transfer

How to use

Inspect both connectors and mating ports for dirt or damage before connecting. Firmly hand-tighten the SMA male to the corresponding SMA female connector; avoid overtightening with tools to prevent damage. Align and screw the PL259 connector onto the matching SO-239 or UHF socket until it is secure. Use the cable for short interconnections between transceivers, antennas, tuners or test equipment, and avoid excessive bending near the connector ends to preserve mechanical integrity and RF performance.

Usage recommendations

For best results, use the cable where short, low-loss connections are required and where a 50 Ω system is maintained. Keep the cable run as short and straight as practical, protect connectors from moisture and corrosion, and avoid tight bends or repeated flexing at the connector junctions. If higher power handling, longer runs, or different connector types are needed, select an appropriate cable and adapter that match system requirements.
