Coaxial cable N male to N male Rangeful HF400 20 m, 50 Ω, full copper, hex outer

Rangeful HF400 coaxial cable with N male to N male connectors, 20 m length and 50 Ω impedance is designed for RF signal transmission where low loss and stable connections are required. The cable uses full copper conductors and N-type connectors with hex outer bodies to provide consistent electrical contact and a secure mechanical grip. Its construction aims to minimize attenuation and preserve signal integrity for antenna feeds, repeater links and laboratory test setups.

Advantages

This coaxial cable combines a 50 Ω impedance with full copper conductors to ensure low resistance and reliable RF performance across typical communication bands. The N male to N male terminations with hex outer bodies facilitate firm tightening with a wrench and reduce the risk of connector rotation or loosening. The 20 m length offers flexibility for positioning equipment while maintaining acceptable insertion loss for short to medium runs.

Suitable for

• Antenna installations and feeds
• Repeater and base station connections
• Laboratory measurement and test setups
• Radio and RF hobbyist projects

Key specifications

• Characteristic impedance: 50 Ω
• Connector type: N male to N male with hex outer bodies
• Cable length: 20 m
• Conductor material: full copper
• Intended use: RF signal transmission, antenna feeds, test equipment connections

How to use

Connect each N male connector to corresponding N female ports on antennas, repeaters, radios or test instruments. Ensure connectors are threaded by hand to align threads, then tighten the hex outer body with an appropriate torque wrench or spanner to achieve a secure mechanical and electrical connection without over-tightening. Route the cable to avoid sharp bends, kinks and sources of mechanical stress. For outdoor runs, use additional weatherproofing at connector joints if the installation is exposed to moisture.

Usage recommendations

For best RF performance, keep run lengths as short as practical and avoid tight bends (maintain bend radius recommended for HF400-type coax). Inspect connectors periodically for corrosion or loose fittings, and replace or re-terminate the cable if any degradation is observed. When used in environments with vibration, verify torque after initial installation and use proper strain relief where needed.
