Abstract : The icing of towers causes both great mechanical and electrical difficulties for the radio and TV antenna equipment in Finland. To obtain real loading information, part of the problematic towers will be equipped with microprocessor controlled instruments to measure the loadings and to collect weather information. Calculation methods will also be tested by comparing the measuring results with theoretical values. Because the mere reinforcement of the structures eliminates only a part of the problems, also the development of more effective deicing methods is strived for. (Author)
