FALSE!!!!!!  Don't even thing about it!

Speaking in rough numbers, Rohn 25 will hardly handle 70 MPH winds
at 40' self supporting, with ZERO antennas.

With any antennas at all, it would fold over.

At 60' in 70 MPH winds, you are roughly over TWICE the design limit of 
moment on the tower with no antennas.  Even Rohn 45 cannot handle this.
And Rohn is about twice as conservative as what I said.
