Rick,
Your analysis is probably appropriate for a sparse set of elevated radials,
each being a significant individual contributor to the radiated field. In
such a case, separate radials for each element -- not bonded where they
cross -- seem to be the appropriate choice for a uniform counterpoise.
I prefer to think of a radial system as an approximation of a solid sheet
rather than individual conductors. In this case, the currents will flow "as
they want to" along the surface. In reality, a significant-sized
counterpoise behaves somewhere between individual wires and a solid sheet. A
poor approximation of a sheet increases the average resistance per unit
area. I'd like mine to be closer to the solid sheet model!
