Determine the isotropic free space loss at 1 GHz for the shortest path to a satellite orbiting the earth at 1000 km from earth now consider the antenna gain of both satellite and ground-based antennas at 16 dB and 9 dB respectively. What is the new free space loss? now assume a transmit power of 100 W at the earth station. What is the power received at the satellite antenna in dB?
