Specifically, SES-GS advises the Commission that for antenna 1, the 11 meter Vertex 11 KPC model antenna, the gain is 51.9 dBi at 4 GHz and 55.4 dBi at 6 GHz. The antenna’s height above ground level is 12 meters, and the site elevation is 1907 meters above sea level. The maximum input power is 501 watts, and the maximum aggregate output EIRP for all carriers is 82.2 dBW. The satellite arc is 60° W.L. to 143° W.L. The eastern and western azimuth angle limits are 122.5° and 232°, respectively, and the eastern and western elevation angle limits are 26° and 30°, respectively. The maximum EIRP density toward the horizon is 42.7 dBW/4kHz. In addition, SES-GS provides the following updated data associated with the emission designators for antenna 1: Frequency (MHz) Emission designator Max. EIRP/Carrier Max. EIRP Density 5925-6425 1M06G7D 60.6 dBW 36.4 dBW/4kHz 5925-6425 2M06G7D 63.6 dBW 36.4 dBW/4kHz 3700-4200 1M06G7D 3700-4200 2M06G7D For antenna 2, the 5 meter Scientific Atlanta antenna discussed in the modification, the maximum input power is 200 watts, and the maximum aggregate output EIRP for all carriers is 67.5 dBW. The maximum EIRP per carrier is 56.7 dBW.
