The LP antennas do what they are meant to do:  cover all frequencies in their 
range.  Maybe we don't need that and should pin point the maximum whatever.  
The SteppIR is a really good choice...and maybe with some EZNEC work an added 
element could really shine.

But for height:  A quick look at any antenna book will show the futility of a 
magic height over flat ground.  All over the place.

But for fun:  Model a Yagi at the edge of a 30 to 40 degree slope and check the 
vertical pattern for various heights for various bands.  Hint:  Start at 40 
feet.  Something interesting happens. Check out Moxon's book.   Of course, then 
you lose the ability to rotate the antenna to other directions unless you are 
on a cone.

Have fun
