Coaxial UHF Cable Rangeful HF240 50 Ohm, 3 m, PL-PL connectors

Rangeful HF240 is a 3 m coaxial UHF cable with 50 Ohm characteristic impedance and PL-259 (PL) male connectors at both ends. It is intended for RF signal transmission in amateur radio, CB and other UHF applications where a short, flexible jumper or fixed-length cable is required. The cable construction balances flexibility with adequate shielding to maintain signal integrity over a short run between transceivers, tuners and antennas.

Advantages

The HF240 cable offers a standardized 50 Ohm impedance compatible with most modern radio equipment and accessories. At 3 m length it provides a convenient span for bench setups, mobile installations or short rooftop connections without excessive slack. PL-259 male connectors at both ends ensure straightforward mating with UHF/SO-239 interfaces commonly used in amateur and CB radio equipment. The cable’s flexible outer jacket and moderate diameter make routing and handling easier in constrained spaces while preserving low-loss performance for typical UHF frequencies.

Suitable for

• Short RF jumper between transceiver and antenna or antenna tuner
• CB radio installations in vehicles or fixed stations
• Amateur radio setups and portable field stations
• Connections in test benches and temporary RF assemblies

Key specifications

• Characteristic impedance: 50 Ohm
• Cable length: 3 m
• Connector type: PL-259 (male) at both ends
• Construction: flexible coaxial cable with outer jacket suitable for indoor and sheltered outdoor use
• Application range: UHF and HF frequency bands typical for amateur and CB radio

How to use

Connect one PL-259 male connector to the transceiver or tuner and the other PL-259 male connector to the antenna feedpoint or socket using a compatible SO-239 receptacle. Ensure connectors are fully threaded and hand-tightened, avoiding excessive force. Route the cable to minimize sharp bends and kinks; maintain gentle curves with a radius larger than the cable diameter. For outdoor use, protect exposed connector junctions from prolonged moisture and ensure the cable is secured to avoid movement that could stress connectors.

Usage recommendations

For best performance, keep runs as short as practical and avoid coiling excess cable near the radio. Use proper strain relief at connector ends and inspect connectors periodically for corrosion or loose threads. When deploying outdoors, seal connector interfaces with appropriate weatherproofing materials to prevent moisture ingress.
