You might want to check on the ham-law reflector, but I suspect that a flat 
restriction to one tower would not comply with the PRB-1 requirement to 
"reasonably accommodate".  What if you wanted to build a 80 meter phased 
array, with 1/2 wave verticals?

  In a somewhat similar situation with OTARD antennas (dishes etc), someone 
put up 5 poles and I don't recall how many dishes, the city said no, you 
only get one, the courts said, uh uh, the premption doesn't work that way, 
you have to allow whatever the person wants unless you can articulate a 
specific historical preservation or safety concern.

OTOH, you could be in the delightful(?) position of having the law on your 
side, but needed to spend many tens of kilodollars to prove it.

The tower for wind generator idea is a clever one to get around it.  And, 
of course, is there a requirement that you have to have your windmill 
actually generate any electricity in any significant amount (assuming you 
don't want it for power, although a wind generator is a nifty idea in and 
of itself).  Perhaps a suitable clutch arrangement to keep the generator 
from turning (although the prop still does) and making noise when you're on 
the air? Or, can you use the windmill for pumping?
