Coaxial cable N male to N female Rangeful HF400 3 m, 50 Ω, full copper

Coaxial cable Rangeful HF400 N male to N female, 3 m length, 50 Ω impedance and full copper conductors is designed for RF signal transmission and antenna connections where low loss and stable impedance are required. The cable assembles an N male connector on one end and an N female connector on the other, enabling direct connection between N-type devices in amateur radio, professional installations and laboratory test setups. The construction focuses on conductor continuity and shielding to preserve signal integrity across the 3 metre run.

Advantages

The full copper central conductor and copper shielding provide improved conductivity and reduced insertion loss compared with plated alternatives. N-type connectors offer robust mechanical coupling and consistent impedance matching at common RF frequencies. The 3 m length balances reach and manageable signal attenuation for mid-range links, while the flexible HF400 cable jacket supports routing in confined installations without compromising shielding effectiveness.

Suitable for

• Connecting antennas to transceivers and RF amplifiers
• Laboratory test setups and measurement rigs
• Base station links and repeater installations
• Amateur radio and temporary field deployments
• Interconnecting N-type equipped RF devices

Key specifications

• Impedance: 50 Ω
• Length: 3 m
• Connector A: N male
• Connector B: N female
• Conductor material: full copper (core and shield)
• Cable type: HF400 coaxial
• Frequency range: suitable for common RF and microwave applications (typical N-type performance)
• Jacket: flexible protective outer layer for indoor and sheltered outdoor use

How to use

Connect the N male end to the corresponding N female socket on your transmitter, antenna or test instrument and tighten the connector by hand until secure; use a suitable torque wrench only if a specific torque value is required by equipment specifications. Route the cable to avoid sharp bends and do not compress or kink the cable, as mechanical deformation can increase loss and change impedance. For repeated installations, inspect connector threads and central conductors for wear or contamination and clean with appropriate RF-grade solvent if necessary.

Usage recommendations

For optimal performance, keep cable runs as short as practical and avoid parallel routing alongside high-power AC lines. When used outdoors, protect connectors from moisture with tape or weatherproof boots. If precise insertion loss or VSWR figures are critical for your application, verify performance with a network analyzer and choose the shortest suitable length or a lower-loss variant where required.
