No, hams are not crazy. Stacking antennas at HF is really done
not to get the 2 or so db of stacking gain it is to get
a better take off angle pattern - it is this change in pattern
that accounts for the 10 db changes in signals when switching
between the stacked antennas.
I keep telling folks that it is height above the ground that
makes the most diffrecne not the size of the antenna.
