Many years ago when topbanders were looking for better efficiency and something thart would radiate with limited space lots there was the "Z" 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.
