I'm not considering that the ground wave signal _provides_ any of that
low-angle DX coverage. It is the direct radiation existing in the
radiation pattern of the monopole at low elevation angles that can do
so. No ground reflection is necessary to create that field - it is
launched by the monopole itself.

Below is a link to a clip from Terman's Radio Engineers Handbook, 1st
edition, showing that the greatest single-hop range for skywave
signals occurs from the radiation of the monopole at elevation angles
of less than ten degrees. But looking at a NEC far-field analysis
this would seem impossible, due to the greatly reduced fields in this
sector that NEC shows for a vertical monopole over real earth.

This clip was done for MW frequencies, but the concept would apply
equally at HF, would it not?

I for one, think you correct. What is "launched" at the antenna obeys
physics laws at 100 ft., 1000 ft., 10,000 ft., 100,000 ft., 1,000,000
ft. ... the signal does not ever suffer magical, mystical, supernatural
manipulations--EVER!
