In a Long range microwave communication system operating at a 9GHz, the transmitting and receiving antennas are identical and are separated by 10000 meter. To meet the signal to noise ratio of the receiver the received power must be at least 10μw.Assuming the two antennas are aligned for maximum reception to each other including being polarization matched, what should the gains (in dB) of transmitting and receiving antennas be when the input power to the transmitting antenna is 10W.
