Coaxial cable Rangeful HF400 BNC male to PL259 UHF, 50 Ω, 2 m

Rangeful HF400 coaxial cable with a BNC male connector on one end and a PL259 UHF connector on the other provides a 2 m, 50 Ω cable solution for RF signal connections. The cable is intended to link equipment with BNC and PL259 terminations without impedance mismatch, supporting HF, VHF and UHF applications commonly found in amateur radio and related RF setups. The construction is designed to offer a reliable physical connection and maintain the characteristic impedance across the length to reduce reflections in typical installations.

Advantages

The cable combines two common connector types—BNC male and PL259 UHF—on a single 2 m lead, enabling direct connection between devices that use these terminations. With a 50 Ω nominal impedance, it is suitable for many RF systems where consistent impedance is required. The fixed length simplifies installation in rigs and bench setups, and the coaxial construction provides shielding to limit external interference while preserving signal integrity for transmitting and receiving within its intended frequency ranges.

Suitable for

• Connecting amateur radio transceivers to antennas or adapters that use BNC and PL259 connectors
• Linking HF, VHF and UHF components in test benches and temporary setups
• Interfacing equipment in radio labs, field operations, and vehicle installations where a 2 m lead is convenient

Key specifications

• Connector A: BNC male
• Connector B: PL259 (UHF) male
• Characteristic impedance: 50 Ω
• Cable length: 2 m
• Cable type: HF400 coaxial

How to use

Ensure both devices are powered down or transmitting is disabled before connecting to avoid potential damage. Align the BNC male connector with the matching BNC female socket and push and twist until it locks. Thread the PL259 connector onto the corresponding UHF female socket until hand-tight; do not over-tighten with tools to prevent damage. Route the 2 m cable to avoid sharp bends and close proximity to large sources of electrical noise. After connections are secure, power up equipment and verify presence of expected signal levels and VSWR for the installation.

Usage recommendations

Use the cable for short runs where a 2 m length is appropriate and maintain gentle routing to preserve the coaxial geometry. Inspect connectors for corrosion or damage before use and replace the cable if the shielding or dielectric appears compromised. For critical or long-distance RF links, consider using professionally terminated low-loss coaxial assemblies and measure system SWR to confirm acceptable performance.
