Coaxial cable Rangeful HF400 50 Ohm, PL259 to SO239 UHF, flexible 20 m

Flexible 20 m Rangeful HF400 coaxial cable with 50 Ohm impedance and UHF PL259 to SO239 connectors. Designed for HF and VHF radio links, antenna connections and amateur radio setups, the cable provides consistent 50 Ω signal transmission and flexibility for routing in confined spaces. The durable outer jacket protects the inner conductor and dielectric while maintaining pliability for temporary or permanent installations.

Advantages

The cable combines a standard 50 Ohm impedance with UHF PL259 to SO239 terminations to ensure compatibility with common amateur and commercial radio equipment. Its 20 m length reduces the need for additional connectors and adapters, while the flexible construction simplifies installation through conduits and around obstacles. The construction balances shielding and flexibility to minimise signal loss and maintain a stable connection between transceiver and antenna.

Suitable for

• HF and VHF radio transceiver to antenna connections
• Amateur radio (ham) station setups
• Temporary field deployments and portable stations
• Routing through tight spaces, conduits, and enclosures

Key specifications

• Impedance: 50 Ohm
• Length: 20 m
• Connector types: PL259 (male) to SO239 (female), UHF standard
• Cable type: HF400 coaxial
• Construction: flexible outer jacket with inner conductor and dielectric suitable for radio frequency transmission

How to use

Connect the PL259 (male) end to the radio transceiver output or coaxial socket and the SO239 (female) end to the antenna feed point or antenna connector. Ensure both connectors are fully seated and hand-tighten where applicable; avoid over-tightening to prevent damage to connector threads. Route the cable to minimise sharp bends and kinks; maintain gentle radii to preserve cable impedance and reduce insertion loss. For outdoor use, secure the cable with appropriate clamps and avoid prolonged exposure of connectors to moisture without protective covers.

Usage recommendations

Use this HF400 50 Ohm cable for standard amateur and commercial HF/VHF links where PL259 to SO239 compatibility is required. For best performance, keep the cable run as short as practical, avoid repeated flexing near connectors, and use weatherproofing on external connections to extend service life.
