You need electrical mass Doc (low impedance) or electrical
inertia, not physical mass.
The job of a radial is to spread the voltage and current
around. By definition that must include electric and
magnetic fields that occur at voltage and current points.
This is why a few elevated resonant radials are such a bad
thing for loss when the radials place intense electric and
magnetic fields in the loss media below the antenna.
This is also why we should never trust a model that uses
homogeneous media ( a media that doesn't even match the
actual soil in the application) would tell us how to
optimize a system.
Adding more radials over a larger area spreads the fields
around, making the fields and directly coupled current less
dense. The spreading is what decreases losses, not the
physical mass or resonance.
