... A single icing episode can produce damage to the tower, antenna, feedline, and associated structures simultaneously. Ice cracker cones are effective in protecting the guy wire grips. Ice bridges protect attachments from falling ice, including transmission lines leading from the tower to the transmitter building. Ice shields are inexpensive and effective protection for side-mounted antennas, microwave dishes, beacons, and other tower attachments. 4. WIND. It is impossible to build a tower that will withstand all winds. Wind damage is the single largest cause of broadcast tower ... more than 75 percent of broadcasters' losses. Tower owners and chief engineers should focus attention on gaining an in-depth understanding of climatological data in the areas where their towers are located. Once the potential for weather extremes is recognized, steps can be taken to install the equipment necessary to minimize the possibility of loss. Basically, the type of tower, quality of construction, and installation must be appropriate for the topography and able to withstand the climatological extremes in the area where the facility is located. 2. Lightning. Lightning accounts ... the possibility of vandalism, fencing provides protection for these key areas from being struck by trash removers or farm equipment.
