12.2.4 CAPITAL COST VS POWER AND FREQUENCY RESULTS A beam taper of 5 dB and a beam collection efficiency, ng, of 90 percent were selected to exhibit trends of capital cost as frequency and power are varied. The results in capital cost per unit output power are given in Figures 12-6 and 12-7 for the low and medium cost combinations of power source and orbital operations, with microwave costs at the medium level. All costs are expressed in 1975 dollars. The factors entering into the overall cost are shown in Figures 12-8 through 12-11.
