Shielded Coaxial Cable CNT-400-FR, Black

CNT-400-FR is a premium 50-ohm coaxial cable featuring low attenuation, high shielding performance, and a halogen-free, flame-retardant jacket. Developed for professional RF and antenna installations where high operational reliability and long service life are required.

CNT-400-FR is a high-performance coaxial cable from CommScope, designed for installations where both electrical performance and fire safety are critical factors. The cable features a 50-ohm impedance, low attenuation up to 6 GHz, and effective shielding of 90 dB, ensuring stable signal transmission even in environments with high levels of interference.

The halogen-free, flame-retardant outer jacket meets CPR class Dca s2 d2 requirements, making CNT-400-FR suitable for installation in public buildings, industrial facilities, and technical areas. The cable is also flexible and durable, with a wide temperature range for both installation and operation.

Typical applications:

  • Antenna and RF installations
  • Mobile, radio, and communication systems
  • Indoor installations with fire safety requirements
  • Industrial and commercial networks
  • Broadcast and wireless infrastructure

Key advantages:

  • Low attenuation for RF and microwave systems
  • Halogen-free, flame-retardant jacket (CPR Dca s2 d2)
  • 90 dB shielding for high immunity to interference
  • Suitable for both indoor and outdoor installations
  • Robust construction for professional installations
