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.
