 ```Don't count on ice support. Several years ago some big 1000 ft towers in Clayton NC were iced up. When the sun got on the towers and melted the ice on one side, several of the towers collapsed.

This must be some kind of "magic length" as Rohn 45 with no ice will support 22 ft^2 and with 1/2" of ice it will support 25 ft^2. The ice must be acting like a bracing component? The 20' row appears to be the only height where the number "don't make sense". 73 de Bob - KØRC in MN Message: 4 Date: Mon, 2 Aug 2010 10:51:34 -0400 From: "Lee J.
