    Actually @ 70 MPH, it'll take 21 sq. ft. per Rohn  specs. Don't forget 
to add back in the 8.0 sq.ft. that they take off of the  tower capacity for 
a symmetrical antenna mount which you're not going to use.  It's in the 
General Notes.

the 130 foot mark but would like to  stack 6X6 60ft boom 20 meter antennas 
one at 135 the other at 73".  The  phyllistran guys would be at 43 86 and 129 
more or less.  Would adding a  4th set of guys make a difference?  

    No. The limiting factor is leg strength. Be sure  to follow the LXC 
Prime Directive to "DO what the manufacturer says." There  are online Rohn 
catalogs or get one of the new ones from the factory.
