Coaxial cable Rangeful PL259 to SO239 HF400 50Ω flexible 12 m

Rangeful HF400 coaxial cable with PL259 (male) to SO239 (female) connectors is a 12 m, 50 Ω flexible transmission line designed for HF and VHF radio installations. The cable combines a flexible jacket and a construction intended to deliver low signal loss across the intended frequency range, making it suitable for antenna feeds, transceiver connections and amateur radio setups that require a reliable, easy-to-route cable of moderate length.

Advantages

The cable offers a standard 50 ohm impedance compatible with most HF and VHF equipment and connectors, and its PL259 to SO239 termination provides straightforward mating with common amateur and professional radio gear. The flexible HF400 construction eases installation in confined spaces or along walls and masts, while the 12 m length reduces the need for additional adapters or extension patches. Materials and connectors are selected to maintain consistent electrical characteristics and to minimise insertion loss over typical operating frequencies.

Suitable for

• Antenna feed lines for HF and VHF radios
• Connecting radio transceivers to external antennas
• Amateur (ham) radio station setups and temporary field installations
• Indoor or outdoor routing where a 12 m flexible coaxial lead is required

Key specifications

• Characteristic impedance: 50 Ω
• Connector pair: PL259 (male) to SO239 (female)
• Cable type: HF400-style flexible coaxial
• Length: 12 m
• Intended frequency range: HF and VHF bands (design for low loss across these bands)
• Construction: flexible outer jacket with shielded inner conductor designed for outdoor or indoor routing

How to use

Route the 12 m Rangeful HF400 coaxial cable between the radio transceiver and the antenna or between equipment with PL259/SO239 interfaces, ensuring connectors are clean and free of corrosion prior to mating. Hand-tighten the PL259 onto the SO239 and avoid excessive torque to prevent damage to connector threads. When installing outdoors, secure the cable along supports or masts with appropriate non-compressive clamps or UV-resistant ties, and maintain gentle bends to preserve the cable's electrical characteristics. If the installation passes through building entries, use a proper gland or grommet to protect the cable and maintain weather sealing.

Usage recommendations

To minimise signal loss and preserve connector life, keep cable runs as direct as practical, avoid sharp bends or repeated flexing at connector ends, and inspect connectors periodically for wear or corrosion. For long-term outdoor installations, consider additional weatherproofing at connector joints and ensure proper strain relief where the cable is fixed.
