The transmit power of a TV satellite is 40 W and the diameter of the parabolic antenna at the transmit antenna is 80 cm. The diameter of the parabolic antenna at the receiver is 120 cm. Distance from the satellite to the earth is 40 000 km, frequency is 11.5 GHz. Given that both antenna efficiencies are equal to nt = nr = 0.7, how many dBm is the signal received by the receive antenna? (Hint the antenna aperture of a parabolic antenna with diameter D is given by (pi × D^2 )/4
