The modeling I have done, for the most part shows
the towers does not impact the pattern, there are 
exceptions ... especially as to vertical arrays,
or yagi elements too close to the tower itself.

What I have also noted though that many seem to 
overlook is too many antennas, too close together.

What good does it do for the overall RF system
performance if you isolate the guying, either with
insulators, or insulated guys, and then hang multiple 
inverted vee type antennas with wire elements crossing
into the lower yagi in a stack's field?

Sometimes less is better, than more <... that is as
to interactions between antennas.>

Just another thought to ponder ...
