Coaxial cable Rangeful HF400-RPSM-NF-20 20 m, full copper, 50 Ω

Coaxial cable Rangeful HF400-RPSM-NF-20 is a 20 m, 50 Ω RF cable with full copper conductors intended for signal transmission between radio equipment, antennas and test instruments. The cable is designed to provide low-loss connectivity and reliable impedance matching for applications that require a robust copper 50 Ω coaxial link. Its construction supports consistent RF performance across common amateur, professional and laboratory frequencies.

Advantages

The full copper conductors reduce skin-effect losses and provide stable electrical contact over time, while the 50 Ω characteristic impedance ensures proper matching with standard RF devices. The 20 m length offers extended reach for flexible placement of radio or test equipment without the immediate need for additional connectors or adapters. The cable's construction focuses on durability and repeatable signal performance in typical RF setups.

Suitable for

• Amateur radio station antenna feedlines and temporary outdoor setups
• Professional RF installations and on-site measurement connections
• Laboratory test benches linking signal generators, spectrum analyzers and receivers
• Situations requiring a 50 Ω coaxial link with minimal insertion loss over 20 m

Key specifications

• Length: 20 meters
• Impedance: 50 ohms
• Conductor material: full (solid/stranded) copper conductors
• Intended use: RF signal transmission between radio, antenna and test equipment

How to use

Connect the appropriate connector ends to the transmitting and receiving devices, ensuring secure threaded or push-fit engagement as required by the radio, antenna or test instrument. Route the cable to minimize sharp bends and avoid crushing, kinking or tight coiling that can alter impedance and increase insertion loss. For temporary outdoor use, keep connectors protected from moisture and dirt with appropriate caps or weatherproofing. Verify system SWR or return loss after installation to confirm correct impedance matching.

Usage recommendations

For best long-term performance, avoid repeated flexing near connector ends, store the cable loosely coiled to prevent permanent deformation, and use connector protection when exposed to environmental conditions. When used in measurement setups, allow a short warm-up and re-test the connection if components are changed to ensure consistent readings.
