One antenna that does work well even over poor ground is a 4-square with
elevated radials, preferably above .05 wavelength in height. In my case
I changed to a different design - instead of orienting the elements in a
1/4 wavelength "box", I use custom designed 3/16 wavelength spacing to
give a broader pattern which allows me to better hear/work ZS, Southern
Africa and UA0 when pointed at Europe.

In my opinion, there is no reason to put up the more complex Delta
Loop and
not make it a vertically polarized antenna.
Hi Ed,
You cited the most important reason in the paragraph above --
vertically polarized antennas are strongly dependent on good soil to
work well, horizontal antennas don't care what the soil is, they only
care about height. Poor soil is a VERY good reason to NOT bother with
any vertically polarized antenna.
