Coaxial cable Rangeful HF240 10m 50Ω with BNC male to PL259 UHF connectors

Rangeful HF240 is a 10 m coaxial cable with 50 Ω characteristic impedance, fitted with a BNC male connector on one end and a PL259 (UHF) connector on the other. Built for HF, VHF and UHF radio applications, this cable provides a conventional impedance match for many transceivers, antennas and test instruments. Its length and connector combination make it suitable for linking radios to antenna tuners, transceivers to external antennas, and for temporary test or bench setups where a reliable RF path is required.

Advantages

The cable offers a consistent 50 Ω impedance for minimal mismatch losses across HF to UHF bands and robust mechanical connectors at both ends for secure mating. The combination of a BNC male and a PL259 UHF connector enables compatibility with a wide range of amateur radio equipment and test devices. Constructed to typical coaxial standards, the cable balances flexibility and shielding to maintain signal integrity during normal field and bench use.

Suitable for

• Connecting transceivers to external antennas or antenna tuners
• Radio test benches and measurement setups
• Temporary station wiring and field portable radio installations
• Interconnecting equipment with BNC and PL259 UHF interfaces

Key specifications

• Length: 10 m
• Impedance: 50 Ω
• Connector 1: BNC male
• Connector 2: PL259 (UHF)
• Intended frequency range: HF / VHF / UHF bands
• Typical use: RF signal transfer between transceivers, antennas and test equipment

How to use

Connect the BNC male end to the corresponding BNC socket on the transceiver, antenna tuner or test instrument, and screw the PL259 (UHF) connector onto the matching SO-239 or UHF socket on the antenna feed or other equipment. Ensure connectors are fully engaged and hand-tight; avoid excessive torque to prevent connector damage. Route the cable to minimise sharp bends and kinks, and keep it clear of engines, sharp edges and sources of heavy mechanical stress. For bench measurements, keep connections short and stable to reduce unintended loss or interference.

Usage recommendations

Use the cable in installations where a 50 Ω impedance is required; inspect connectors periodically for corrosion or looseness and replace the cable if shielding or dielectric damage is visible. For longer permanent runs or environments with elevated RF power, consider cables with higher power rating or lower loss characteristics and verify connector compatibility before installation.
