It is a well know fact that a dipole has 8dBi gain when it is 1/2
wavelength high do to the ground reflection. ON4UN is saying in his
book that these compressed delta loops only have 1.6 dBi gain over
average ground.
This link is to a slide show for a presentation I've done several times
about this set of issues. It doesn't address delta loops, but it does
compare horizontally and vertically polarized antennas at various
mounting heights.
