Coaxial cable N male to N female Rangeful HF400 30 m, full copper, 50 Ω

Coaxial cable N male to N female Rangeful HF400 30 m, full copper, 50 Ω is a 30-metre RF coax designed for low-loss transmission between devices requiring 50 Ω impedance. The cable uses a full copper conductor and standard N-type terminations (N male to N female) to provide consistent electrical contact and mechanical durability for antenna feeds, test bench connections and amateur radio installations.

Advantages

The cable combines a solid copper center conductor with a 50 Ω characteristic impedance to minimise insertion loss and preserve signal integrity across VHF and UHF ranges. Standard N-type connectors ensure robust threaded connections and stable performance under moderate mechanical stress. The 30 m length offers extended reach without the need for additional adapters, while the construction reduces signal reflections and maintains consistent impedance matching between equipment.

Suitable for

• Antenna feeds for base stations and portable setups
• Laboratory and test equipment connections
• Amateur radio transceivers and repeaters
• RF signal routing between transmitters and amplifiers
• Temporary or fixed installations requiring 50 Ω cabling

Key specifications

• Cable type: coaxial, RG/HF-style construction with full copper center conductor
• Connectors: N male to N female, threaded coupling
• Length: 30 metres
• Characteristic impedance: 50 Ω
• Conductor material: solid/copper (full copper conductor)
• Typical application frequency range: VHF/UHF and nearby RF bands (suitable for general RF use)
• Design focus: low insertion loss, stable impedance matching

How to use

Inspect the connectors and cable for visible damage before installation. Thread the N-type connectors onto mating connectors by hand until snug, then tighten to finger-tight plus a small additional turn if necessary; avoid overtightening to prevent damage to connector threads. Route the cable to minimise sharp bends and avoid kinks — maintain bend radius recommended for HF-style coaxial cables. When used as an antenna feed or between RF equipment, verify 50 Ω matching at both ends and perform an SWR or return-loss check after installation to confirm acceptable performance.

Usage recommendations

For best long-term performance, avoid repeated flexing near the connector ends, protect the cable from prolonged UV exposure if installed outdoors, and use appropriate strain relief at each termination. Periodic visual inspection and cleaning of connector interfaces will help maintain low-loss connections.
