K26 LSZH 50/75Ω Coaxial Cables

Application

The 50Ω cables are HF transmission coaxial cables for GSM antennas, and the 75Ω cables are HF transmission coaxial cables for cameras (type KX6), and video surveillance (type 11 RTC). The Halogen-free cables are suitable for laid on hooks, and pulled through walls or through technical ducts.

Standard

  • RATP K26
  • Fire Performance: NF C 32070.2.2

Cable Construction
