Page 75: Appendix A Grounding Practices And Lightning Protection Information
There is no practice or formula which can completely eliminate the above risks, but we at Wireless, Inc. believe that good grounding and bonding practices can significantly reduce the risk of many of these hazards. We have included a bibliography at the end of this appendix which... - Page 76 WaveNet Link AX Installation and Operations Manual Protection Arrangements The purpose of any protection arrangement should be to provide a suitable path to ground for the lightning current, to ensure adequate bonding between structures and all metalwork on the site and the common grounding system in order to reduce the side flashing, and to attempt to prevent the entry of flashes or surges into the building.
- Page 77 Weatherproof grounding kits are available from antenna manufacturers. Note: Many of the cables used by Wireless, Inc. have braided rather than solid outer conductors; this type of grounding is not appropriate. In these cases we recommend the use of Wireless, Inc.
