And to complicate matters further the max antenna height being talked
about being around 3-4 wavelengths off the ground is going to break the
radiation pattern up into a number of lobes at various vertical angles.

For that reason alone I think it is still worth modelling. There will be
specific heights where the horizontal radiated component is at a maximum
and this is likely the most desirable. . .

Modeling will show that at great distances from the antenna, the
horizontally radiated field is zero from any horizontally polarized
antenna over ground.

Please see http://www.cebik.com/vhf/ex6.html on the topic.

Near the end of the article he gets into the horizonatally polarized
less than 1WL interrupted loops typical of 6m (halos, squares and
triangles).

For more, he also has an article on HOHPLs (horizontally oriented
horizontally polarized loops 1WL and greater).

Worth reading and observing the models used.
