Coaxial RF Cable Rangeful HF240 BNC Male to PL259 UHF 50 Ω, 3 m

Coaxial RF cable Rangeful HF240 BNC Male to PL259 UHF 50 Ω, 3 m is a 3-meter coaxial lead designed for RF interconnection between equipment using BNC and PL259 (UHF) interfaces. With a characteristic impedance of 50 ohms and construction targeted at HF and VHF frequency ranges, this cable serves as a practical link for amateur radio stations, radio test setups and other RF applications that require reliable, low-loss signal transfer between devices with differing connector types.

Advantages

The cable provides straightforward mating between BNC male and PL259 UHF connectors, eliminating the need for additional adapters when connecting transceivers, receivers, antennas or test instruments. Its 50 Ω impedance maintains proper matching for HF and VHF systems to reduce reflections and preserve signal integrity. The 3 m length offers flexibility in placement while keeping signal path loss moderate for typical amateur and laboratory distances.

Suitable for

• HF and VHF amateur radio transceiver to antenna tuner connections
• Interconnection of receivers, transmitters and test equipment
• Laboratory and bench RF measurements where BNC to PL259 mating is required
• Temporary station setups and field portability where a 3 m lead is convenient

Key specifications

• Connector A: BNC male
• Connector B: PL259 (UHF)
• Impedance: 50 Ω
• Length: 3 m
• Intended frequency range: HF and VHF applications

How to use

Ensure both devices are powered off or transmit functions are disabled before connecting to avoid damage. Align the BNC male connector with the BNC female jack and push with a quarter-turn to secure. For the PL259 end, align the plug with the SO-239 or compatible female UHF connector and screw the coupling nut until hand-tight to form a secure mechanical and electrical connection. Route the cable to minimize sharp bends and avoid kinking; secure with cable ties if necessary. After connection, verify continuity and correct impedance matching in your system before transmitting at full power.

Usage recommendations

Use this cable for applications within HF and VHF frequency ranges and moderate power levels typical of amateur radio and test equipment. Avoid excessive bending near the connectors and do not expose the cable to prolonged outdoor weather without additional protection. For high-power transmitters or VHF/UHF professional systems, verify power-handling and VSWR requirements before use.
