It's funny to think that really terrible ground can have an advantage

Free space is just about the most terrible "ground"
that one can imagine. :-)

So much disinformation by W8JI School of DC circuitry :-)

Modeling various configurations shows benefits of good ground, especially
for taller than 1/4 wave radiators.
Myth that half wave radiators do not need ground is spreading like snake oil
wild fire. They need it but "looking" for it further out, not just at the
base.
I will anytime trade good ground (mirror) for lossy (RF sponge) ground. Its
just where the radiator is "looking" for the mirror, taller one - further
out, enhancing signals at lower angles.
3/8 vertical with some 3/8 physical length radials start morphing into far
field.
