... 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, the possibility of signal loss is increased. It is critical that both the tower site and the transmission building be readily ... 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. Cadwelding the connections is recommended. All tower attachments should be grounded to the tower, and these connections should be inspected annually, since poor connections can cause severe harm to equipment. Power lines must be protected with surge arrestors and line chokes. Phone lines should be protected with MOVs (Metal Oxide Varistors) . In lightning zones 6 or higher, lightning dissipation systems are highly recommended. ...
