Coaxial cable Rangeful HF400 BNC male to PL259 UHF, 50 Ω, flexible HF400, 25 m

Rangeful HF400 BNC male to PL259 UHF, 50 Ω, flexible HF400, 25 m is a 25-metre coaxial jumper designed for RF signal transmission between equipment with BNC and PL259 (UHF) terminations. The cable uses HF400 flexible 50 Ω coax construction to provide consistent impedance for HF and VHF/UHF frequencies. One end is fitted with a BNC male connector and the other with a PL259 (UHF) male connector to enable direct connection between transceivers, antennas and other coaxial components that require these terminations.

Advantages

The cable’s HF400 flexible construction balances mechanical flexibility and electrical performance, reducing stress at connector interfaces and easing routing over longer runs. A nominal 50 Ω impedance supports common amateur radio, transceiver and antenna applications across HF, VHF and UHF bands. The fixed 25 m length provides a reliable jumper for installations where a longer lead is required without intermediate connectors. Connector types (BNC male to PL259 UHF male) allow compatibility between devices that use BNC and UHF connections without adapters.

Suitable for

• Connecting amateur radio transceivers to external antennas
• Linking receivers or test equipment with BNC output to UHF-equipped devices
• Temporary or semi-permanent installations where a 25 m flexible RF lead is needed
• Signal routing in field operations, portable stations and workshop setups

Key specifications

• Cable type: HF400 flexible coax
• Impedance: 50 Ω (nominal)
• Length: 25 metres
• Connector A: BNC male
• Connector B: PL259 (UHF) male
• Suitable frequency range: HF and VHF/UHF bands (typical for 50 Ω RF cable)
• Construction: flexible outer jacket for routing and strain relief

How to use

Connect the BNC male end to the BNC female socket on transceivers, receivers or test instruments and securely tighten the PL259 male onto the corresponding UHF (SO-239) socket of an antenna, antenna tuner or radio. Route the cable to avoid sharp bends and high-tension points; leave some slack at the connector ends to reduce mechanical stress. Verify connections are fully seated and, when possible, check SWR or signal level after installation to confirm proper signal transfer.

Usage recommendations

For best performance, avoid running the cable parallel to high-power mains wiring and minimize sharp bends (maintain bend radius recommended for flexible HF400 cable). When used for fixed outdoor routes, protect connectors from moisture with suitable sealing methods. Periodically inspect connectors and cable jacket for wear and replace the cable if inner shield or dielectric damage is visible.
