Coaxial cable Rangeful HF240 BNC male to PL259 UHF 50 Ω, 0.3 m

Rangeful HF240 coaxial cable with a BNC male connector on one end and a PL259 (UHF) male connector on the other provides a short, flexible RF link for 50 Ω systems. At 0.3 m length the cable is intended for short patch connections between transceivers, antennas, tuners or test instruments. The construction supports reliable signal transfer for amateur radio, CB and general RF applications where a compact adapter lead is required.

Advantages

The cable offers matched 50 Ω impedance along its length to minimise reflections and maintain signal integrity. A short 0.3 m length reduces insertion loss and keeps feedline routing tidy in cramped setups. Dedicated BNC male and PL259 (UHF) male connectors provide common, mechanically stable interfaces for a wide range of radio equipment and accessories. The flexible jacket and standard connector formats make the cable convenient for temporary connections and bench testing.

Suitable for

• Linking HF/VHF transceivers to external antenna connectors or patch panels
• Short jumper between radio equipment and antenna tuners
• Temporary or bench test connections for signal measurements
• CB and amateur radio interfacing where a BNC-to-UHF adapter is needed

Key specifications

• Impedance: 50 Ω
• Cable length: 0.3 m
• Connector A: BNC male
• Connector B: PL259 (UHF) male
• Typical use: RF patch cable for HF/VHF applications

How to use

Connect the BNC male end to the corresponding BNC jack on the device and screw the PL259 male connector onto the UHF/F connector of the other device until it seats firmly. Ensure connectors are clean and free of debris before mating to avoid poor contact and signal degradation. Keep the cable gently routed without tight bends to preserve the characteristic impedance and avoid excessive strain on connector joints.

Usage recommendations

For best performance, use this short coax for connections where low insertion loss and minimal reflection are important. Avoid using this lead for long runs — for extended distances select a larger, lower-loss coaxial cable. Inspect connectors periodically and replace the cable if you observe damaged connectors, exposed shielding, or intermittent contacts.
