Many years ago when topbanders were looking for better efficiency and

which was essentially a way of feeding a 1/2 wave sloper from a tapped
coil L/C circuit at the shack end by running the first 1/4 wave of wire
close to the ground (were it was claimed to do minimum radiation since
it was voltage rather than current fed) and then sloping it upward to a
tree or pole with the top portion doubled back horizontal to the ground

This is a fallacy. Where you feed the antenna doesn't affect where
it radiates. You would get the same results if you fed it as a bent
dipole at the junction between the first 1/4 wave and the upward
sloping portion. Which is to say poor results.
