what homebrew HF antenna produces the most groundwave?
"Richard Harrison" wrote
Kraus in the 3rd edition of "Antennas" gives a simple answer
in Figure 16-35 on page 569. A 0.64-wavelength tall vertical
radiator produces the greatest field strength at one mile
in the direction of the horizon.

....and subparts (c) and (e) of that figure clearly show the high-angle
sidelobe centered at about 58 degrees elevation from an 0.64-lambda monopole
that may cause self interference -- per Roy Lewallen's post earlier in this
thread.
