Coaxial cable Rangeful N male to N female Twin HF240 50 Ω 12 m

Rangeful Twin Coaxial Cable HF240 with N male to N female connectors is a 12 m, 50 Ω twin-feed coaxial assembly designed for RF signal transmission and antenna connections. The cable combines two matched 50 ohm cores in a single jacket to ensure consistent impedance and reduced phase imbalance for applications that require parallel feeds or twin runs with N-type terminations.

Advantages

This twin coaxial cable offers stable 50 Ω characteristic impedance and low loss across common RF bands, while N-type connectors provide robust mechanical coupling and reliable electrical contact. The twin construction simplifies routing of two signals together, reducing installation complexity compared with two separate coaxial runs. The cable jacket and connector mounting are engineered for secure connections and predictable RF performance in test setups and installations.

Suitable for

• Amateur radio antenna feeds requiring N-type terminations
• Laboratory and test bench RF setups with parallel or differential feeds
• Professional RF installations where matched twin feeds are needed
• Repeater and duplexer connections that require durable N connectors

Key specifications

• Impedance: 50 Ω characteristic
• Length: 12 metres twin cable assembly
• Connector types: N male to N female on paired cores
• Cable type: Twin coaxial construction with matched cores
• Typical application: RF signal and antenna connections

How to use

Connect the N male connector to the corresponding N female port on the transmitter, antenna, or test instrument and attach the N female connector to the target device or antenna feedpoint. Ensure connectors are threaded and hand-tightened, then use a torque wrench to the recommended torque for N-type connectors where precise mechanical coupling is required. Route the twin cable to avoid sharp bends and sources of mechanical stress; maintain bend radii above the cable's minimum specified value to preserve characteristic impedance and minimise insertion loss.

Usage recommendations

Inspect connector interfaces before installation to remove debris and verify contacts. For outdoor installations use appropriate weatherproofing at connector junctions. Avoid excessive pulling force on the cable assembly and secure the twin run at intervals to prevent movement and strain on the connectors. For critical measurement work, verify insertion loss and VSWR with test equipment after installation.
