We discuss a new concept in lightning location system (LLS). Specifically, it is an optimum method of lightning signal strength and a parameterization method of the site gain curve estimation in LLS. Site gain correction curves for all DFs for 1989 were found by using the data observed in an LLS of three direction finders (DFs) in Beijing region. The result shows that the curves, as a function of measured bearing, only include the one- and two-cycle sinusoidal components. It also indicates that the larger the site errors which DF has, the larger the amplitude of the site gain curve. In this LLS, the ranges of site gain are 0.9-1.2, 0.85-1.05, 0.9-1.1 for DF1, DF2 and DF3 respectively. For discussion, we suggested a model for site gains due to dipole radiation. This model can be used to reasonably explain the characteristics of structure of site gain curves.
