Re: [TowerTalk] Rohn 25G

I guess it depends on what windload you want the tower to withstand.

If it was my tower I would use more than 2 guy wires. Best to consult the 
Rohn 25 drawings.
According to Rohn my tower can take 120mph, the mast 105mph and the beams 
100 mph. I hope I never need to put that to the test.
