As a followup to my question, I guess the concept or the question is
no different than if it referred to a dipole instead of radials on a
vertical. The concern is protection from the high voltage at the end
of the wire, and the potential of it causing a fire.
So it is really a very general question, considering the numbers of
antennas hams are having to disguise or hide inside their homes these
days.


In a vertical dipole, you have only one "radial" which carries
the same currents and voltages as the upper vertical element.
Seems to me, when one has multiple radials, the energy in each
radial has to be the total energy available divided by the number
of radials. Therefore, the voltage at the ends of 1/4WL radials
should decrease as the number of radials is increased.

This seems to be another way that distributed networks differ
from lumped circuits. We might even be able to calculate the
voltage at the ends of the radials, given the number of radials
and the total power available to the radial system.
