Another company that was selling a rotating tower was Tri-Ex. The towers
come in 120, 130, and 140' sizes. They sell the complete system including
the base rotor and all guy material as the Clement Tower...my lit said it
was $8,000 list about 10 years ago. Uses the T-20 sections which are
slightly bigger than 55G.
Looks good but expensive if still being sold.
