[TowerTalk] Rohn 25G and Ice Loading

[Joe - WDØM]

Lived on the coast of Alaska for quite a few years - we had a heck of an 
ice storm, resulting in up to 3 inches of ice on my tower and 
antennas.  There is a picture on my old web site:

The picture appeared in QST a couple of years ago.  The tower stood tall - 
and we had winds of 125 mph as well.  The antenna pictured is a Mosley 
Pro57B-40, with a Cushcraft 5 element 6 meter yagi on top.  The guys were 
Philystran, and had a 3 inch coating of ice on them.  I'd guess that it 
takes a lot to bring down a well-guyed Rohn 25G.

73,
