Richard,
You state that you used a dipole to compare with, which was at the same
height !.
Which antenna was altered so that the elevation angle of maximum gain
was the same for both antennas.such that max gain measurements
were truly comparable?
Where was the height of the "curtain" measured or referred to
so that "same height" could be justified ?
( You also did say it was for SW use which is certainly different
to ground wave use)
Presumably, the comparison was for the same type of polarization
and ignored differences created by the side addition of other
types of polarization.
Without further information the "Facts" could be seen as
correct to plus or minus 100 percent measurement error!



And that sums up most antenna testing rather well!
