I am installing a 10-metre tower on a rocky spit in coastal setting. There is only a thin layer of organic matter covering the bedrock. There is a power line running along the spit just over two tower lenghts to the west. It has been suggested that I might be able to drive a grounding rod in there and run a long length of heavy grounding wire two it? Is this feasable?
Other suggestions are to use a grounding plate, or bore out holes for three grounding rods and back fill them with a conductive substance.
Does anyone have any experience with this? Don't want the protection to cost more than the tower installation.
