Tower Icing and Shields
The tower is the most visible component of any transmission facility. It is also the most vulnerable to hostile elements. When icing occurs frozen deposits form a snow and ice shell on antenna and tower components. When the ice thaws on the tower, segments of ice fall or sail causing significant damage to antenna elements.

Antenna elements are particularly susceptible to falling ice. Ice can have a weight of 56lbs per cubic foot and can cause significant damage to unprotected tower antenna and accessories. Ice shields and radomes can offer some degree of protection.

Entering the winter season reminds us to take into account the importance of protection from shedding ice and the additional weight and wind load added to the tower during the colder months of the year.
