Coaxial cable Rangeful PL259 to PL259 HF400 50Ω flexible 20 m

Rangeful HF400 50Ω coaxial cable, 20 m, with PL259 to PL259 connectors is a flexible RF lead intended for HF, VHF and UHF signal transmission. The cable features a flexible outer jacket and standard PL259 (UHF) male terminations at both ends, providing a continuous 50 ohm link between transceivers, antennas and test equipment. The 20-metre length supports temporary runs, field operations and installations where a low-loss, easy-to-route cable is required.

Advantages

The cable combines a flexible HF400-type construction with standard PL259 connectors to deliver reliable 50Ω performance across HF, VHF and UHF frequency ranges. The flexible jacket facilitates routing and handling in confined spaces or during portable operation, while the PL259 terminations provide broad compatibility with amateur radio transceivers, base station equipment and many antenna types. The assembly is suitable for repeated connections and disconnections in field or workshop environments.

Suitable for

• Connecting amateur radio transceivers to antennas and tuners
• Temporary and field antenna installations for contesting or portable operation
• Linking base station equipment, SWR meters and test instruments
• Short to medium runs where a 20 m flexible 50Ω cable is required

Key specifications

• Impedance: 50 ohm characteristic impedance suitable for HF/VHF/UHF
• Length: 20 metres of flexible coaxial cable
• Connector type: PL259 male termination at both ends (UHF style)
• Cable construction: HF400-type coax with flexible outer jacket for easy routing
• Application: Radio frequency signal transmission with low to moderate insertion loss over 20 m

How to use

Route the cable between the transmitter or transceiver and the antenna feed point or between equipment units, avoiding tight bends and sharp kinks. Ensure PL259 connectors are clean and free of debris before mating. Align the PL259 plug with the mating SO239 or PL259 socket and hand-tighten where applicable; if using a wrench, apply light torque to avoid over-tightening the connector body. For outdoor or temporary deployments, secure the cable along supports to reduce strain on connectors and prevent accidental movement.

Usage recommendations

To maintain performance, avoid repeated extreme flexing near the connector ends and protect outdoor connections from prolonged moisture exposure. Periodically inspect connectors for corrosion and replace any damaged sections. For permanent outdoor installations consider additional weatherproofing at connector joints and appropriate support to prevent cable sagging over long runs.
