Why is this important? My 60 radials per vertical in my 80m 4-square are
buried a couple of inches below the surface and I consider that grounded.
Also where the radials cross each other I did not bond them together. So
how many db have I supposedly lost?
It is important that the ends are not grounded.
Some would argue that putting ground rods at the end of radials doesn't
really help. In most cases you can do well, perhaps better with #12 or
#14 THHN insulated wire laying on the ground. You will only then need
about 90-100 feet for each radial due to the velocity factor of the wire
itself. If you run out of space due to your lot size you can run the
ends at right angles. It is important that the ends are not grounded.
IMHO what you are trying to do is cause the ground system currents to
travel in those wires rather than being dissipated in the earth thus
improving the system efficiency. You can pin the wires down with
large galvanized nails, , pounded into the ground after a single turn
around them. (U clips are also available by the hundred lot from
DX-Engineering) Normally after two weeks the sod will cover them and
they will be invisible and allow the lawn mower to pass over without a snag.
