Assignment:
Assume that two antennas are half-wave dipoles and each has a directive gain of 3dB. If the transmitted power is 1W and the two antennas are separated by a distance of 10 km, what is the received power? Assume that the antennas are aligned so that the directive gain numbers are correct and that the frequency used is 100 MHz.
a) 4 * 10^-17 W
b) 20 W
c) 2.27 * 10^-9 W
d) 16 W
