SABC has satellite with a transmit power of 100 W and is 100 percent efficient. The diameter of the reflector of the transmit antenna is 80 cm while that of the receiver is 120 cm and 70 percent efficient. The distance between the receive antenna and transmit antenna is 40 000 km, frequency is 11.5 GHz. Calculate: N.B: Take path loss is equal to free space path loss. 2.1.1 Transmit power in dBm 2.1.2 The wavelength 2.1.3 Gain of the transmit antenna 2.1.4 Gain of the receive antenna 2.1.5 Power received by the antenna
