    1. A geostationary satellite receives a power of -102.96dBW (5.05 ×10-11 W) at its receiver for the link with f =14.2GHz, GR=20dB, GT =30dB, and additional losses of 5dB. For this system, calculate:
  2.   The power that is being transmitted from earth station; and                         
  3.   The satellite parabolic antenna half power beam width, if its radius is 45cm.
