... speed for which a tower was designed. Reviewing current EIA-E data and requesting a periodic structural analysis of a tower will improve the chances of weathering a storm without substantial damage. Ocean surge can be a cause for damage to towers located as far as 10 miles inland. Earthquakes will damage towers, particularly those that are guy wired. The major danger of flooding is the damage it causes to the electrical apparatus in the transmitter building. The cost of replacing the structure and equipment can exceed $100,000. Floating debris can produce tower failure. 6. AN INACCESSIBLE TOWER SITE. Sites are often chosen because of a higher elevation to help reduce the need for additional tower height. These sites are often inaccessible during certain times of the year, making repairs impossible. As a result, ... possibility of lightning losses. Here is a checklist to help minimize tower damage by lightning. Lightning rods should project well above the tower beacon. Use binoculars to verify that the rods are in place and in good condition since severe lightning hits may vaporize them. Guy wire anchor points should be grounded to the nearest radial by copper strap. For grounded towers, at least four 10-foot rods must be bonded to the tower base and in contact with the groundwater table. Soil must be tested to determine conductivity. For insulated towers, the ball gap should be clear of debris so that the bare metal is exposed. Insulated towers should have a static drain choke connected between the feedline and the station ground. Insulated towers should have two 12-foot loops in the feedline between the tower and the transmitter housing ...
