Several thoughts.  First, take a look at this tutorial presentation I've 
done for several ham clubs and at Pacificon.

 From my own experience, I can tell you that a 30M dipole at 70 ft ain't 
exactly chopped liver, although I just paid tree climbers put mine at 
100 ft. Before that, I used one at 35 ft to work FT5ZM, halfway around 
the world.  :)

Second, any vertical, array or not, will be quite dependent both on the 
quality of your soil.

Third, with the exception of a half wave radiator, any vertical array 
will be quite dependent on the quality of the radial system.

Fourth -- a 3-el vertical array is likely to give you no more than about 
5 dB over a single vertical.

Fifth -- see the piece on my website about "should I put my HF vertical 
on my roof?"
