High speed grounding kit for CELLFLEX® LCF 158

Rev : H | Rev date : 08 Jul 2021

This Grounding Kit has been developed by RFS for the CELLFLEX® cable series. The Grounding Kit body facilitates a proper attachment to the coaxial cable, ensuring that the performance of the coaxial cable is not being compromised. The tin plated copper mesh provides a secure, low resistance contact to the cable outer conductor. The installation only takes a few minutes. No additional sealing with mastic and electrical tape required.


  • Compatible with both copper and aluminium cable types i.e. one Grounding Kit for both outer conductor materials eliminates the risk of faulty Grounding Kit installation and helps to keep inventory down.
  • This kit has been verified by independent labs to withstand the damaging effects of lightning current in excess of 100kA 8/20µs according to EN 50164. The copper wire provides the most practical and effective low inductance transfer of lightning induced current to ground.
  • No influence on the electrical transmission characteristics of the coaxial cable.
  • Robust mechanical design.
  • UV resistant according to DIN EN ISO 4892-2 (Plastics - Methods of exposure to laboratory light sources - Part 2 Xenon-arc-lamps).
  • Ozone resistant according to DIN 53509 (Testing of rubber - Determination of resistance to ozone cracking).
  • Compliant to RoHS (EU 2002/95/EC) and CRoHS (China SJ/T11363-2006) i.e. usable on a global basis.
