My experience is that 80 to 100 ft plays very well AFTER DARK
from 10 thru 40M but LOWER is BETTER
during DAYLIGHT HOURS on the high bands.
NO SINGLE HEIGHT will cover ALL the angles
supported by the ionosphere. I like 35 to 40 ft
for my high angle antennas and 60 / 120 ft for
my low angle high band antennas.
90 ft is good for 20, 30, and 40M.
90 ft SUCKS on 10 / 15 IMHO, at least from KY, TN, ALA.
(This assumes FLAT terrain in all directions)
