[TowerTalk] Rohn 25G

[Larry]

In general at 100 feet Rohn suggests 3 guys 33, 66, and 99 feet. Somewhere 
around 75 feet and below it is generally 2 guys as I recall. But it does 
depend on the load. How much do you have above the top of tower and a myriad 
of other factors need to be considered.

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.
