But doesn't this maximum load apply only at the point shown on the 
drawing, i.e. above the highest guy point? The original poster is 
planning to mount several antennas almost uniformly distributed over the 
entire tower (in between the guys). What rules apply in this scenario 
and how can one figure out the maximum load in this case which Rohn does 
not address at all?
