Coaxial cable Rangeful PL259 to PL259 HF400 flexible 50 Ω, 3 m

Flexible HF400 coaxial cable by Rangeful with PL259 to PL259 connectors, 50 Ω impedance and 3 m length. The cable is designed for HF, VHF and UHF radio frequency use, providing a plug-and-play connection between devices with PL259 jacks. It combines a low-loss HF400 construction with flexible outer sheath to allow easy routing in confined spaces and repeated handling during field or base-station operations.

Advantages

The cable offers reliable shielding and consistent 50 Ω impedance for stable RF signal transmission. Flexible HF400 dielectric and braid construction reduce insertion loss over short runs while allowing tight bends without kinking. PL259 male connectors on both ends ensure mechanical compatibility with common SO-239 sockets and provide secure threaded coupling. The 3 m length balances reach and signal performance for typical radio and antenna setups.

Suitable for (tasks / use cases)

• Connecting transceivers to antenna tuners, transceivers or coaxial antenna feeders
• HF, VHF and UHF amateur radio station wiring and temporary field deployments
• Base station and mobile radio installations where PL259/SO-239 interfaces are used
• General RF signal routing where a flexible 50 Ω coaxial lead is required

Key specifications

• Impedance: 50 Ω
• Cable type: HF400 (flexible coaxial construction)
• Connector type: PL259 male on both ends
• Length: 3 m
• Intended frequency ranges: HF, VHF, UHF
• Shielding: braided shield with outer jacket for mechanical protection

How to use

Align the PL259 connectors with the mating SO-239 or PL259 socket, engage the threaded coupling and tighten by hand until secure; use a suitable tool only if a firmer connection is necessary, taking care not to over-torque the connector. Route the cable avoiding sharp edges and extreme bends to preserve performance. For outdoor or exposed installations, ensure connectors and any exposed terminations are protected from moisture and corrosion using appropriate sealing methods.

Usage recommendations

For best RF performance, keep cable runs as short as practical, avoid coiling excess cable tightly, and maintain gentle bend radii. Inspect connectors periodically for secure fit and corrosion, and replace the cable if the outer jacket or braid shows significant wear.
