Just to note that the graphics I linked to were part of the 1937 benchmark 
experiments and I.R.E. paper of Brown, Lewis & Epstein of RCA Laboratories, 
and is the basis for the FCC requirements for the monopole systems of AM 
broadcast stations to this day.

The physics of these vertical monopole antenna systems hasn't changed.

The complete BL&E paper is available as item 4 in the list at
