... for an antenna location. Each addition to a tower affects the ability of the structure to withstand the adverse weather conditions for which it was designed. A structural engineer should be engaged to inspect the tower every three years or when adding additional equipment. 10. INADEQUATE SECURITY. Security is becoming more of an issue, particularly in certain areas where towers and studios are located. The property should be fenced in, or at the least the road or walkways should have locked gates. Depending where the facilities are located, floodlighting roads, walks, and gates is essential, as well as the building, parking areas, and entrances. Lighting is a major factor in deterring vandalism and other types of crime and reducing the possibility of injury. The transmission building, the tower base, and guy ... 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 ...
