YES! Even short hills make pretty good towers, especially for 
horizontally polarized antennas. And N6BT has reported disciplined 
experimental work showing that radiation/reception of verticals benefits 
strongly from being at the edge of a dropoff in the direction of the 
dropoff. I heard him present this work at Pacificon several years ago, 
and for this NCJ piece, K6OIK developed a model in H.O.B.B.I.E.S that 
predicted the effect. H.O.B.B.I.E.S. is modeling software that can build 
far more complex models than NEC, including surrounding objects and terrain.
