Coaxial UHF Cable Rangeful HF240 50 Ω, 3 m length

Rangeful HF240 is a 50 Ω UHF coaxial cable, 3 m long, designed for reliable RF signal transmission between antennas, receivers, transceivers and test equipment. The cable provides a consistent characteristic impedance of 50 ohms to reduce reflections and support efficient power transfer in UHF frequency ranges. Its 3 m length makes it suitable for both fixed and portable setups where a short, robust connection is required.

Advantages

The cable provides a standardized 50-ohm characteristic impedance for stable impedance matching and reduced standing waves. Its coaxial construction shields against external interference, improving signal integrity in installations and field tests. The 3 m length offers flexibility for equipment placement without excessive cable clutter, and the physical design is suitable for repeated connection and disconnection in portable use.

Suitable for

• Connecting UHF antennas to radios and receivers
• Interfacing transceivers and portable communication equipment
• Laboratory and field testing of RF devices
• Short-run installations where 3 m cable length is sufficient

Key specifications

• Characteristic impedance: 50 Ω
• Cable type: UHF coaxial
• Length: 3 m
• Primary use: RF signal transmission and antenna connections

How to use

Connect the appropriate UHF connectors on each end of the HF240 cable to the corresponding sockets on the antenna and the radio or test instrument, ensuring threads are hand-tightened where applicable to secure the connection. Route the cable to avoid sharp bends and points of mechanical stress; maintain a gentle bend radius to preserve shielding and characteristic impedance. For temporary or portable setups, verify continuity and check signal levels after connection to confirm proper operation.

Usage recommendations

Use the cable in environments protected from prolonged moisture exposure; while coaxial construction provides shielding, prolonged wet conditions may affect connectors. Avoid kinking the cable and keep connector interfaces clean to maintain low insertion loss. Select the 3 m length for installations where short, direct runs are practical; for longer runs, consider cables with appropriate length and loss characteristics.
