Another way to think about this is that your antenna starts at ground.
But that's WRONG. The earth is a big resistor. Radials SHIELD the
antenna from the lossy earth, providing a return for the fields produced
by the antenna and a low resistance path for the return current.
When
you have a long ground lead (any length) from the radial system to your feed
point that lead is part of your antenna.
Correct -- but BOTH that lead AND the radials are part of the antenna.
It doesn't matter that your feed
point may be a few feet above ground, the whole distance from the top of the
vertical right to the ground plane is going to look like part of the
antenna.
not "ground plane," RADIAL SYSTEM. Otherwise this is correct.
