It's because the the wind pressure for the ice condition is reduced to 75% of the Basic Wind Speed. In these cases the Basic Wind controls not the ice.

Hello,

Has anyone looked at the Rohn specs for using 25, 45, 55 and 65 in
free-standing installation?  If not, take a peek at:

The thing I find particularly odd is the allowed antenna areas with no ice
vs. 1/2 inch ice.  Does anyone know why Rohn says you can have *more*
antenna area with ice than without in many of the listings?  It's most
dramatic on the 65G, letting you go up to 50' free-standing before the no
ice figures start to overtake the ice figures.  Weird..
