Consider a lunar base with an X-Band transmitting parabolic antenna at frequency 10 GHz. The transmitter power is 22 dB. Communications are maintained with the receiving ground station on Earth that is equipped with a 12-foot-diameter dish antenna.

1. What is the wavelength of the radio waves?

2. What is the gain of the transmitter in dB?

3. Assume atmospheric loss is -3dB, what is the gain of the receiving antenna?

    Question1. A U.S. or Canadian broadcasting licence for a (large) FM radio station stipulates a maximum broadcast power of 100 kW. At any distance from the broadcast antenna the intensity doesn’t quite follow the inverse square law that is described for spherical waves in the videos lectures, because of reflection of the signal off of the ground. But the inverse square law is not a bad approximation, so let’s use it a) Find the intensity of the radio signal from...
