ABSTRACT
This chapter examines protection techniques for the present generation of towers, antenna system equipment, and protection methods and equipment, and helps the reader to analyze new and ever-changing environments. Protecting service personnel from the threat of a direct lightning strike, secondary flashing, and controlling differences in potential between different parts of their bodies during a lightning event must be integrated into any comprehensive tower protection scheme. In typical tower-building arrangements, the tower is normally subject to more frequent and larger lightning currents than the station building. The intensity of lightning storm activity throughout the world varies by location. Convection storms are usually local in extent, of relatively short duration, and account for the majority of storms in the United States. Frontal storms extend over greater areas, may continue for several hours, and are usually more dangerous, causing greater damage than convection storms.
