If the total energy flowing into the monopole system with buried radials
is dictated only by its hard-wired connection through the transmission
line back to the transmitter, then what is accounting for the reduction of
its radiated power?
Nothing I said even remotely implies loss would be the same as things are
changed, so the question or "exercise" is completely meaningless to the
topic.
I said the system is complex. I said radial current comes from more than one
cause. I said it is far more than just a simple transference of current from
soil to the radials.
The radials are directly exposed to antenna fields. The radials are directly
connected to the antenna feedline. If they are anywhere near soil or in
soil, they are coupling to the soil. The soil is part of the system. A fence
near the radials is part of the system. Unconnected wires are part of the
system. A lake or ocean near the antenna is part of the system.
It is a huge mix of things interacting, not just a boy and his radial, with
the radial collecting currents only from the soil.
By definition, soil or not, the radials have current. By definition,
connected to the feedpoint or not, the radials (like any conductor around an
antenna) will have current.
But if that isn't enough, the field strength change of a model doesn't even
prove what physically happens. The model just estimates or calculates a
result. It might be spot on, but it just is a calculated summary of results
of many things.
