OK, experts: The basement is going in. I'm going to do the full peripheral ground system per the PolyPhaser books. Question (the answer to which I cannot find in the book): Should the ground wire be

as Probably OK for Western Washington, but here in the frozen tundra of the Northeast, four feet deep is the standard for getting under the frost line. 73, Dick, WC1M -- FAQ on WWW: http://www.conte

More to the point, what does the frost line have to do with buried wire, anyway? If you don't bury radials that deep, why would you have to do so with a perimeter ground wire? For that matter, all of
I'll jump in here and suggest that it has to do with moisture is (relatively) conductive whereas ice is not. The object of using bare wire is so that it too can bleed off charge. Frozen ground is no
Good question, Pete. In theory, the idea of going below the frost line is to prevent heaving of whatever is buried, so it doesn't reappear at the surface some day, from earth movement of the freeze/t

In New England, we get a phenomenon called "frost heaves". It happens when the ground freezes, melts, and refreezes in late winter. It causes the ground to heave and buckle, often as much as a foot o
To: <towertalk@contesting.com> Snip (Discussion about putting safety ground below frost line.) Pete, The missing information here is that frozen electrolytes are insulators. When the ground freezes,
Heaving is bad, real bad. First, if it occurs unevenly (highly probable), it can put enormous strain on conductors and connections, breaking conductors and pulling wires out of connectors or worse. S

Boy, I would think you'd want the ground grid to be as deep as reasonable because this grid may be dissapating all or part of the energy from a lightning strike. When I worked as an electrician in Wy
I don't believe for a second that any county in the Atlanta area has a descernable frost line.... Of course, for a water line, you don't want it freezing AT ALL. But you're not going to see much, if
Suggest you take that up with the utility company. But more to the point, the idea was where to get the information, not whether you believe it or not. 73 Ed -- FAQ on WWW: http://www.contesting.com/
Two entirely separate issues. antenna radials, either buried or elevated are part of the RF circuit and act as a counterpoise to the radiating element. If the earth under the radiating element had go
Sheesh, you light weights just don't know frost. We had water mains freezing and breaking at 12 feet two years ago here in town. And NO my ground grid isn't below 12 feet. 73 es have fun with your "

Frozen ground won't absorb surge energy. 73, Bob AA0CY PS What is a french drain? More to the point, what does the frost line have to do with buried wire, anyway? If you don't bury radials that deep,
Most of the reason for the depth of burial on an industrial site is related to mechanical protection issues over time ... if its under the ground some one will dig it up the deeper you go though the
