When you feed a time varying current to the mesh it is best to view it
in small parts, say a square in the mesh. The hole is a static field
alongside the applied current flows. This same current generates a
displacement current which encircles the static field as it returns
to the initial current flow. Of course this section is a microcosm of
the flow pattern of the applied varying current which is continually
flowing.

Is this true of a discone? I'm under the impression the current flow
is identical whether metal rods or wire mesh is used in the antenna's
construction.
