The report consists of three parts. The first is a computer analysis of the reduced height performance of a four-element Yagi antenna over a variety of real earth conditions. The second is a computer analysis of the Yagi antennas as near field detectors in the ANGRN-27 ILS system. Coupled to this is an analysis and experimental check of the reduced height Yagi performance in the MRN-7 localizer antenna modification to the GRN-27 ILS system. The last part is an analysis and prediction of the Yagi performance in a second modification to the GRN-27 system that uses a log periodic type of a localizer antenna. Author
