After uplift the base of No. 13 LOC localizer antenna of ILS system in Chizhou Jiuhuashan Airport, there is no adjustment on ZGU-200-3 (TY) optimized lightning rod. In order to ensure the effectiveness of lightning facilities protection, the lightning part of localizer antenna is assessed and adjusted according to the rolling sphere method. First of all, through the data analysis of localizer antenna on both ends of the runway to ensure whether in the protection zone of lightning belt and ZGU-200-3 (TY) optimized lightning rod or not. Secondly, check the specification compliance of lightning protection engineering according to the technical specification. Finally, through the theoretical and practical factors, the issues of localizer antenna are analyzed and the solution is proposed.
