A continuous-wave (CW) beacon transmitter is located on a satell

A continuous-wave (CW) beacon transmitter is located on a satellite in geostationary orbit. The beacon’s 12 GHz output is monitored by an earth station positioned 40,000 km from the satellite. The satellite transmitting antenna is a 1m dish with an aperture efficiency of 70 percent, and the earth station receiving antenna is a 10m dish with an aperture efficiency of 55 percent. Calculate the received power, given that the beacon’s output power is 100mW.
