Coaxial cable Rangeful HF240 BNC male to PL259 UHF 50 Ω, 0.5 m

Half-meter Rangeful HF240 coaxial cable with BNC male to PL259 (UHF) connectors provides a short, 50 Ω connection for HF and VHF radio systems. The cable is intended as a low-loss jumper between transceivers, scanners, antenna tuners and PL259-terminated feed lines. Its compact length and common connector pair make it suitable for patching, bench testing and tight installations where a reliable RF link is required.

Advantages

The cable maintains a consistent 50 ohm characteristic impedance to preserve signal integrity and minimize reflections. High-quality BNC male and PL259 (UHF) connectors ensure secure mechanical and electrical contact with common amateur and commercial radio equipment. The short 0.5 m length reduces insertion loss compared with longer leads and helps keep feedline routing neat in dense setups.

Suitable for

• Connecting transceivers to antenna tuners or feedlines
• Patching between scanners, receivers and test equipment
• Temporary or permanent bench connections in radio installations
• Compact or space-constrained antenna hookups

Key specifications

• Impedance: 50 Ω
• Length: 0.5 m
• Connector A: BNC male
• Connector B: PL259 (UHF) male
• Cable type: HF/VHF coaxial jumper

How to use

Ensure both devices to be connected are powered off or transmit functions are disabled before making connections. Align the BNC male with the corresponding BNC female receptacle and push-and-twist until it locks. Screw the PL259 onto the matching SO-239 or UHF socket until hand-tight; avoid over-tightening to prevent damage to the connector body. After connecting, verify continuity and correct antenna SWR where applicable before transmitting at full power.

Usage recommendations

Use the cable for short interconnections only and avoid routing it alongside high-current power lines to reduce potential interference. Inspect connectors regularly for corrosion or looseness and replace the jumper if outer braid or dielectric shows visible wear.
