High speed grounding kit for CELLFLEX® LCF 12

Rev : J | Rev date : 06 Jul 2022

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 faultyGrounding 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 50kA 8/20µs. 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.
