Dear Dave, LF Group, I have tried this - turning the plane of the loop horizontal more-or-less nulls out all the signals, tending to confirm the theory that there isn't much horizontally polarised signal near ground level. A side effect with a high-Q tuned loop is that if it is near the ground, it will be knocked out of tune by the combination of extra stray capacitance and the "shorted turn" effect of the ground.
