[WISPA] Mountain Top Grounding
I have a site I am putting in on a mountain-top consisting of stacked rocks. Well, they were stacked by glaciers, Techtonic movements, Paul Bunyan etc... Mostly 6-30 across with bedrock downthere somewhere. Do any of you have a site like this? How did you or the site owner ground the site? I don't see grounding rods working really well. ryan WISPA Wants You!

Re: [WISPA] Mountain Top Grounding
All of my sites are like that. Your real ground is the Power company neutral. They pound a rod at every meter, transformer, and splice box. Each pole also has a copper plate on the bottom with the weight of the pole on it. All the way back to Hoover Dam. Drive the ground rods at a little bit of an angle, drive lots of them, one at each Tower leg and each corner of the building. Connect them all together in a circle (Halo.) Try to route the #4 copper ground wire inside the building so it is hard to steal. Cad weld it if you can. Use a rod driver, looks like a fence post driver, if one only goes 1/2 way use it anyway. Cut it off and sharpen the end with a grinder and drive the other half. The tower set in concrete is also ground, connect it in the Halo along with every conduit that is nearby. Ground is ground the world around. D. Ryan Spott wrote: I have a site I am putting in on a mountain-top consisting of stacked rocks.

Re: [WISPA] Mountain Top Grounding
The standard approach is to build a ground plane, which can consist of an array of e.g. #12 stranded radiating outward in all directions from the base of your tower, to a distance equal or greater than the height of the tower. You don't have to bury these cables; they can float on or above the dirt as convenient. Tom S. - Original Message - From: D.
