     Depending on the load and wind speed rating for the site, it can come in
many different configurations.  A typical 90 footer for 15 sq. ft. at 70 MPH
takes 11.3 yards of concrete.  BTW, it's in the book.

        About a year or so ago, Rohn announced the availability of SSV to
amateurs.  They make the top most (smallest) sections with rotor plates and
thrust bearing plates.
While they are nice towers, they are more work than your average 25G or 45G.

      A crane is a cheap and fast way to put one of these up.  After the
sections are assembled on the ground, it only takes an hour or two to stack
100 feet of tower.  You want to assemble the tower loose and then tighten
everything with a rattle gun (impact wrench) after it's all in the air.
 Otherwise you might have trouble getting the sections together.

>Just get the book ( ask for prices, too)!
    Yes, get the book.
