Abstract : The study included interviews with station personnel and other efforts to identify typical station construction and practice, as well as analytical treatments of the transients induced by EMP on station antennas and power line. Most likely sources of damage are determined and the possibility and time requirements of effecting repairs are estimated. Station experience with lightning and a comparison of direct lightning strokes to the antenna with the EMP caused surges are included. Recommendations are given for measures which may reduce EMP damage or the extent of its effects. In most cases these are limited to procedures or low cost improvements. Conservative overdesign to achieve very high reliability is not currently recommended for stations participating in the EBS. (Author)
