Default "Quarter wave ground mounted radials are a waste of wire."

"Quarter wave ground mounted radials are a waste of wire and a hold over
from the olden days. Check the antenna handbook, the new philosophy is
more and shorter. The thing is that the bulk of the energy from the
vertical antenna is near the base of the antenna and this is what you are
trying to capture. A quarter wave radial sounds logical but the planet
will detune it so a quarter wave means nothing to the current."

What say you all?


The ground does detune ground
mounted radials because the fields are attenuated by the
ground. Twice as many 1/8WL buried radials may work as well
or better than half as many 1/4WL buried radials.
