I would think that modeling the elements of the tower +/- 1 or two feet 
from the plane of the antenna would be sufficient, modeling the tower as 
the three legs as thick wires and the steps and braces as thick wires 
roughly approximating their cross sectional area.

As Jim says, generating one set of the braces and duplicating them a few 
times wouldn't be too tough.

What I'd be concerned about is primarily gain ad directivity as long as 
SWR remains within range of what your power amp's output network is 
happy with. My 87As are pretty picky, others I've used not so much.
