Coaxial cable Rangeful HF240 5m, N plug to SMA plug, double coaxial, pure copper

Rangeful HF240 is a 5-meter double coaxial cable terminated with an N plug at one end and an SMA plug at the other. Built with pure copper conductors and a shielded double-coax design, this cable is intended for RF and antenna connections that require consistent impedance, low insertion loss and durable mechanical connections. The cable supports test setups, radio equipment and antennas where signal integrity and repeatable connector performance are important.

Advantages

The double coaxial construction and pure copper conductors minimize signal attenuation and preserve RF performance over the full 5 m length. Precision N and SMA plugs provide stable mechanical mating and good electrical contact in repeated connect/disconnect cycles. The cable’s shielding reduces external interference and helps maintain a consistent impedance, which is important for antenna matching and laboratory measurements.

Suitable for

• Connecting antennas to routers, radios and base stations
• Laboratory and test bench RF measurements
• Portable and fixed radio installations
• Prototyping and signal routing between RF modules

Key specifications

• Cable length: 5 m
• Connector types: N plug (one end) to SMA plug (other end)
• Conductor material: pure copper
• Cable type: double coaxial (shielded double-conductor construction)
• Impedance: consistent RF impedance suitable for antenna and test use
• Typical applications: RF links, antenna feeders, test setups

How to use

Connect the N plug to the corresponding N female socket on the base station, antenna or test instrument, and attach the SMA plug to the SMA female connector on the radio, router or measurement device. Ensure both connectors are tightened by hand and, when applicable, use the recommended torque for each connector type to avoid damage and ensure optimal electrical contact. Route the cable to avoid tight bends and mechanical stress at the connector junctions to preserve performance and longevity.

Usage recommendations

Store the cable coiled without sharp kinks, avoid crushing or heavy loads on the connectors, and inspect connector contacts periodically for corrosion or dirt. For critical measurements or long-term outdoor use, consider additional weatherproofing at the connector interfaces and verify impedance matching in the system to ensure minimal reflection and loss.
