On two meters, yes indeed. But we are talking about 160. To quote Tom above:
"Also, for 160, antennas are near earth. Earth spoils everything. A 160
antenna at 260 feet is like a two meter antenna at 3.25 feet above ground.
... This is 160. The distance ratio for the same behavior on two meters is
80:1. If we look at: http://www.w8ji.com/stacking_broadside_collinear.htm "
