I have been trying to determine the effect of ice
on a tower such as Rohn 25G. Rohn gives antenna
wind loading sizes with and without ice for their
freestanding 25G but not for bracketed or guyed.
I emailed Rohn about obtaining the max antenna
size with ice for their 25G and 45G towers for
a bracketed installation.
The next day I received a phone call from a
gentleman from Rohn explaining that ice is not
really a problem with high wind speed because
the wind blows the ice off the tower. He went
on to say that Rohn installed a tower in
my area (Cleveland/Medina, OH) for a utility company
and that they used the non-ice wind loading
numbers for the installation. He said that
the reason the ice numbers do exist in the
documentation for the freestanding tower
versions is because marketing wanted it.
Is this really true? What are the real effects
of ice on a tower?
