Ed Laport who worked with Brown, Lewis, and Epstein at RCA wrote on page

"The radial disposition of wires in a buried or surface ground system is
dictated by the natural paths for returning ground currents. Meshes opf
crossed wires which were once widely used, should not be used with
vertical radiators because the return paths are not direct


With a fine enough ground spacing, though, I would think that the path is
'direct enough?'

and
eddy-current losses in the closed loop circuits of the mesh can be
appreciable."


I thought the entire point of the ground plane was that the induced currents
are necessary to make up for the current sources that are 'supposed' to have
come from the 'missing' half of the antenna?
