As usual, Terman has answers. See page 882 of his 1955 opus: "Effect of
Ground on the Directional Pattern of Ungrounded Antennas - Image

It`s in the book; math, diagrams, tables, as needed to imagine what

dipole to get rid of horizontal polarization using NEC-2 and is asking
the true experts around the world for comments. We shall now see which

net will understand either way except yourself.
