Coaxial Cable Rangeful HF240 20m 50Ω with BNC Male to PL259 UHF connectors

Rangeful HF240 is a 20 m, 50 Ω coaxial cable supplied with a BNC male connector at one end and a PL259 (UHF) connector at the other. It is designed for HF and general radio frequency use, providing a consistent 50-ohm impedance across the run to ensure reliable signal transfer between equipment with BNC and PL259 interfaces. The pre-terminated cable simplifies installation for transceivers, antenna tuners, and related amateur radio setups where a fixed-length, ready-to-use coaxial lead is required.

Advantages

This coaxial cable features a matched 50 Ω impedance for minimal reflection and stable RF performance. The 20 m length provides extended reach without the need for additional connectors or splices, reducing potential loss points. Factory-fitted BNC male and PL259 (UHF) connectors enable straightforward mating with common radio equipment and antenna feeders. Construction prioritizes consistent electrical characteristics suitable for HF frequency ranges and general-purpose RF connections.

Suitable for

• Amateur radio transceiver to antenna or tuner connections
• Interfacing equipment with BNC and PL259 (UHF) ports
• Temporary or semi-permanent HF station cabling
• Field operations and portable setups requiring a single, long pre-terminated lead

Key specifications

• Length: 20 metres
• Characteristic impedance: 50 ohms
• Connector A: BNC male
• Connector B: PL259 (UHF)
• Intended frequency range: HF and general RF applications

How to use

Connect the BNC male end to the radio transceiver or device fitted with a BNC female socket and attach the PL259 end to the corresponding UHF SO-239 socket on the antenna, tuner, or feedline. Ensure connector threads and locking mechanisms are clean and secure before powering equipment. Route the cable to avoid sharp bends, kinks, and mechanical strain; support the cable along its length if suspended or run through conduits. Verify proper SWR and equipment settings after installation to confirm acceptable RF performance.

Usage recommendations

For best results, avoid tight bends (radius less than 5–10 times the cable diameter), protect exposed connectors from moisture with appropriate sealing or covers, and inspect connectors periodically for corrosion or wear. When used for HF applications, keep cable runs as straight and short as practical for your station layout to minimize loss. Use compatible grounding and lightning protection practices when installing outdoor antenna connections.
