The type of environment is an essential part of the
equation and so results in different environments are particularly
of interest.
This is exactly the crux of the matter. Mathematically, for a given height
of electrically short vertical antenna, a loop having the same diameter (or
else the same length and height) will be the inferior performer IF both are in
the clear--and, it is directional, which may be disadvantageous. If they are
not in the clear, environmental factors degrade the vertical's field strength
faster than the loop's.
This is a dreadfully old and pointless debate. Mathematically and
empirically, the results have long been established. Huge verticals=wonderful at LF if
you have the wherewithal. Short verticals=acceptable if you have adequate
clear space and ground conductivity. Loops of comparable dimensions to small
vertical=compromised performance, but far from useless!
If one is not among the chosen few with half-vast tracts of land for an
antenna farm, he must sometimes make compromises to accomplish anything at all.
