Member Needs Help with Antenna Failures


I attended your Grounding & Bonding seminar in Bowling Green, Kentucky approximately a year and half ago. I would like to ask for your help on a problem that we have been experiencing for the last 9 months or so.

Problem: We started installing antennas for wireless Internet throughout our system; our problem has been with lightning damage to the antennas. Most of these antennas have been installed inside distribution substations and are bonding to the substation grounding grid. We use cad-weld to bond to the grounding grid and we don't seem to lose as many antennas in the substations as we do where antennas are located without a good grounding grid. Other locations where we are experiencing a high number of failed antennas are on water towers and on a distribution utility pole. One would think the water tower would be well grounded, but we are experiencing some problem there.

Have you had any experience with proper grounding/bonding techniques for wireless antennas? I would appreciate any assistance you might be able to provide.
