Another thing that we do is to bond all of the ground rods in an outside ring which is buried in a trench filled with conductive concrete. A layer of the concrete, than the ground ring, and then another layer of that concrete. Expensive? You betcha, but cheap insurance for sites costing well over a million dollars just for the infrastructure. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
