Coaxial cable Rangeful HF400 20m, 50 Ω, full copper, BNC male to PL259 (UHF) connectors

Rangeful HF400 20m is a coaxial cable with 50 Ω impedance and full copper conductors, fitted with a BNC male connector on one end and a PL259 (UHF) connector on the other. The cable is intended for HF and VHF radio frequency use and provides a continuous 20-m connection suitable for linking transceivers, antennas, or intermediary equipment where a 50 Ω interface is required. The construction emphasizes consistent characteristic impedance and reliable electrical contact across both connector types.

Advantages

The full copper conductors reduce resistive loss compared with copper-clad alternatives and help maintain better signal integrity over the cable length. The BNC male and PL259 (UHF) connectors provide compatibility with common amateur radio and commercial radio devices, enabling direct connection between equipment using these interfaces. The 20 m length allows flexible placement of radio equipment and antennas while keeping a single uniform cable run. The cable's 50 Ω characteristic impedance matches typical HF/VHF transceiver requirements to minimize reflections and standing waves when properly installed.

Suitable for

• Connecting HF and VHF transceivers to antennas with BNC-to-PL259 interfaces
• Amateur (ham) radio station setups and field deployment
• Temporary or semi-permanent links between radio equipment in workshops or vehicles

Key specifications

• Cable length: 20 m
• Characteristic impedance: 50 Ω
• Conductor material: full copper core and copper braid
• Connector 1: BNC male
• Connector 2: PL259 (UHF) male
• Intended frequency bands: HF and VHF ranges
• Construction type: coaxial with dielectric insulation

How to use

Connect the BNC male end to the device with a compatible BNC female socket and the PL259 male end to equipment with a SO-239/PL259-compatible socket. Ensure both connectors are fully seated and, where applicable, secure any threaded coupling on the PL259 to achieve a stable mechanical and electrical connection. Route the cable to avoid sharp bends, kinks, and close proximity to large sources of electrical noise. For best RF performance, minimize excessive cable loops and ensure connectors are clean and free of corrosion before making connections.

Usage recommendations

Use this 50 Ω coaxial cable in installations matched to 50 Ω systems; avoid using it in 75 Ω-specific setups. Regularly inspect connectors and the cable jacket for wear, replace the cable if the braid or dielectric is damaged, and keep connector interfaces dry and protected from prolonged exposure to moisture to preserve performance.
