Two identical antennas are 18 km apart and optimally aligned and oriented. One is 8.0 m above the ground and the other is 6.0 m above the ground. There are no hills or valleys between the two locations. The antenna used as the transmitter has a gain of 16.6 dB and the receiving antenna has an effective area of 16.6 m2. We measure the average conductivity of the ground as s = (1.2)10-4 S/m.
(a) What is the free-space wavelength at the operating frequency?
(b) How many dB are lost in transmitting a signal from one antenna to the other?
