Well, I also used a 40m GP with 4 elevated resonant radials about 6' above
ground and I worked an awful lot of really good DX with it!! I found it
to
be about equal to my half-wave vertical dipole for 40m. (Center fed
through
a home-made 1:1 W2DU style current balun)
I'd expect that.
When we tested radials on 40M we measured field strength, and that was
pretty much the point where not much else could significantly change.
However, given the choice of four elevated radials at six feet (equivalent
perhaps of 24 feet height on 160, but who knows if it really scales or not)
or 12-15 in the ground (and who knows if that also scales to 160), I'd use
the buried or laid on earth radials.
