Coaxial cable Rangeful HF400-RPSM-NM-25 50 Ω full copper, 25 m length

Coaxial cable Rangeful HF400-RPSM-NM-25 is a 50 Ω full-copper RF cable with a 25 m length, intended for reliable signal transmission in radio frequency and antenna systems. The cable uses solid copper conductors and a full-copper shield to provide consistent impedance, reduced insertion loss and improved conductivity compared with copper-clad alternatives. Its construction supports indoor installations and protected outdoor routing where flexibility and predictable RF performance are required.

Advantages

The full-copper center conductor and full-copper shielding deliver lower DC resistance and better high-frequency performance than copper-clad steel designs, helping to maintain signal level over longer runs. The 50 Ω characteristic impedance matches standard RF equipment, reducing reflections and ensuring compatibility with most antennas, transmitters and receivers. A 25 m length provides extended reach without multiple connectorized joins, while the cable's jacket and internal geometry are designed to preserve impedance uniformity across the operating band.

Suitable for

• Connecting outdoor or indoor antennas to receivers or transceivers
• Linking RF transmitters and low-power broadcast equipment
• Temporary or permanent installations in home radio, amateur (ham) setups and small commercial sites
• Lab and bench testing where a flexible 25 m coaxial run is required

Key specifications

• Characteristic impedance: 50 Ω
• Conductor material: full copper center conductor
• Shielding: full copper shield
• Length: 25 m
• Cable type: RF coaxial cable
• Typical use: antenna and RF interconnects
• Recommended environments: indoor and protected outdoor routing

How to use

Prepare the cable ends by trimming the jacket and dielectric to expose the center conductor and shield according to the connector manufacturer's instructions. Terminate the cable with compatible RF connectors (type appropriate to the device) to ensure secure mechanical and electrical contact. Route the cable to minimize sharp bends, kinks and close proximity to strong EMI sources. Use weatherproofing methods for any outdoor terminations and secure the cable along its run to avoid strain on connectors.

Usage recommendations

For best RF performance, use appropriate connector types and proper crimping or soldering techniques; avoid exceeding the cable's bend radius; and protect outdoor terminations from moisture. Check system SWR and insertion loss after installation to confirm consistent impedance and acceptable signal levels.
