Coaxial N Male to N Male Cable Rangeful HF400 3 m 50 Ω Full Copper Hex

Rangeful HF400 Coaxial N Male to N Male cable, 3 m, 50 Ω, features full copper conductors and a hex-shaped outer sleeve for stable mechanical connection and corrosion resistance. Designed for RF signal transmission where a reliable, low-loss 50 ohm coaxial link is required, this cable connects N-type male interfaces commonly used on amateur radio equipment, base stations, test instruments and antenna systems.

Advantages

The full copper center conductor and copper shielding provide consistent electrical conductivity and reduced insertion loss across typical VHF/UHF frequencies. The hex-shaped outer sleeve improves grip for tightening and resists rounding when using wrenches, while the N male to N male connector pair ensures weather-resistant threaded connections. The 3 m length offers flexibility for moderate-distance connections without excess slack and supports stable impedance matching for 50 Ω systems.

Suitable for

• Amateur radio transceivers and feedlines
• Base station RF links and antenna connections
• Laboratory and test equipment requiring N-type interfaces
• Outdoor antenna feeds with threaded N connectors

Key specifications

• Impedance: 50 Ω
• Cable length: 3 m
• Conductor material: full copper center and copper shield
• Connector type: N male to N male (threaded)
• Outer sleeve shape: hexagonal for improved wrench grip
• Application: RF/coaxial transmission for VHF, UHF and similar bands

How to use

Ensure both mating N female connectors on equipment are clean and free of debris before connecting. Align the N male threads and hand-start the coupling nut to avoid cross-threading, then use a suitable wrench on the hex sleeve to secure the connection to the recommended torque for N-type connectors. Route the 3 m cable to avoid sharp bends and long unsupported runs; maintain bend radii larger than the cable outer diameter to minimize signal degradation.

Usage recommendations

For optimal performance, inspect connectors periodically for corrosion and retighten if necessary. Avoid exposing the cable to prolonged UV or chemical exposure without additional protection and use appropriate sealing methods in outdoor installations to maintain low-loss RF performance.
