4.1.3 Preliminary Assessment After a number of candidate rectenna sites were identified in a NASA report,* the Mojave rectenna site was selected for detailed study. The initial electromagnetic compatibility analysis addressed the Mojave site to provide electromagnetic impact data for the site characteristic review, and contribute to the development of site selection criteria for NASA and DOE. The Mojave site center coordinates are 35°8' north latitude, 117°30' west longitude. The rectenna covers an area of roughly 100 km^. Figure 4.3 shows a main beam and sidelobe structure for the assumed SPS spacetenna. In Fig. 4.3.
