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

This Rangeful HF400 coaxial cable with N male to N female connectors and a 20 m length is designed for RF and antenna connections where consistent 50 Ω impedance and full copper conductors are required. The cable supports low-loss signal transmission for amateur radio setups, base stations and measurement environments. Construction emphasizes durability and stable electrical characteristics across typical RF frequency ranges used in communication and testing.

Advantages

The full copper center conductor and shield offer improved conductivity and reduced attenuation compared with plated or mixed‑metal alternatives. Using industry-standard N-type connectors ensures secure screw-on mating and good mechanical stability. At 20 m length the cable balances reach and manageable insertion loss for many station and installation layouts. The 50 Ω impedance matches common RF equipment to minimize reflections and preserve signal integrity.

Suitable for

• Amateur radio antenna feedlines and transceiver connections
• Base station and repeater installations
• Laboratory test setups and RF measurement links
• Permanent or temporary outdoor and indoor antenna runs where durable copper cable is needed

Key specifications

• Connector type: N male (one end) to N female (other end)
• Cable length: 20 m
• Impedance: 50 Ω
• Conductor material: full copper center conductor and copper braid shield
• Intended use: RF and antenna signal transmission with low insertion loss

How to use

Connect the N male end to the corresponding N female jack on the transceiver, amplifier or test instrument and attach the N female end to the antenna or matching device. Ensure connector threads are fully engaged and hand‑tightened; use a torque wrench to manufacturer torque specifications if precise tightening is required. Route the cable to avoid sharp bends, kinks and sources of mechanical abrasion; secure with appropriate clamps or ties when used in permanent installations.

Usage recommendations

Avoid excessive bending radii and prolonged exposure to direct sunlight or standing water. Periodically inspect connector interfaces for corrosion and clean contacts before critical measurements or operations. For long runs and high‑power use verify VSWR and consider additional shielding or shorter segments if insertion loss is above acceptable limits.
