Candidate Locations for SPS Rectifying Antennas 1977

a maximum of 3000 ft in New Hampshire and Vermont. Approximately 10 miles of road are covered by each site and the predominant type of land impacted is ungrazed forest land. Figures 4, 5, and 6 show rectenna locations in these states with respect to Standard Metropolitan Statistical Areas (SMSA) and county boundaries. The Middle Atlantic states are New York, Pennsylvania, and New Jersey, which contain 18 percent of the U.S. population on only 3 percent of the land. These data indicate a need for many sites on little land, but there is again the possibility for sea sites. No rectenna sites could be identified in the mostly urban state of New Jersey, but two sites are identified in the densely populated state of New York. Two sites are also identified in Pennsylvania, but one site covers two small towns. These four rectennas displace a maximum of 0.1 percent of the region population or 48 000 persons and average 10 miles to an existing power tie. All of the sites are in mountainous areas and the average elevation range of the impacted areas is 700 to 1800 ft with a maximum of 3000 ft. An average of 10 miles of road is covered by each site, and the only type of land impacted is ungrazed forest land. Figures 7 and 8 show rectenna locations in these states. Wisconsin, Illinois, Michigan, Indiana, and Ohio form the Eastern North Central region with 19 percent of the national population on 8 percent of the land. These states are densely populated and criss-crossed with many major highways so only four land sites are identified; however, there may be potential for water sites in the Great Lakes. Of the four sites selected, two are located in north Wisconsin, one is located in the northern peninsula of Michigan, and the other is located on the main part of Michigan. These four sites displace a maximum of 0.1 percent of the population or 21 000 persons and average 20 miles to the nearest power tie. The average elevation at each site is 200 to 500 ft with an absolute maximum of 1000 ft. An average of 20 miles of road is covered by each site, and the covered land is predominantly ungrazed forest land with some cropland and pasture. Figures 9 and 10 show rectenna locations in these states. The Western North Central region includes North Dakota, South Dakota, Minnesota, Nebraska, Iowa, Kansas, and Missouri. They contribute only 8 percent of the national population on 17 percent of the land and contain 13 rectenna sites. Only one site is identified in Iowa due to its density of small towns and major highways, and the two sites identified in Missouri are questionable because they cover small towns. However, the one missing site and the two questionable sites could be placed in more sparsely populated areas of this relatively flat region. The 13 presently identified rectennas displace a maximum of 0. 3 percent of the population or 46 000 persons and average 35 miles to a
