Abstract : The U.S. Navy has developed a large part of Diego Garcia into a support facility. As a consequence, many receiving antennas have been installed. The search for possible locations for a GEODSS site on the northern part of the island (the most developed part) resulted in the consideration of available areas in and near the receiving antenna field. A natural concern was the possible degradation of the reception characteristics of antennas adjacent to the GEODSS structures in each of the selected areas. This report describes in detail in the antenna field. Since the method is general, only the results are presented for two additional cases. For all cases, the conclusion is that for well-designed receiving systems, the degradation due to the GEODSS buildings would be negligible. (Author)
