What effect would it cause if you ran a wire around the perimeter of the
radials - connecting them together ?
And I guess you could do it again at the half-way point so it resembles a
spider-web.
like a big fence just underground.... could you then reduce the length of
the radials??
I may just try this on a manageabe scale - say 10 meters


Hi Hal,

You would then think of the problem in terms of how far must ground
current traverse through soil to find a conductor? This is a loose
analogy because the current traveling through any patch of ground is
infinitesimal. Rather, it is the efficiency by which the radials
shield the antenna from the "bulk" of ground beneath it. Hence,
thinking of it in terms of 3D and proximity yields a better conceptual
model - further, it allows you to understand why elevated verticals
with fewer radials have an equal capacity for "getting out," or so
reports offer.
