Exercise 4

Communication is to be established between two stations 1.5 (km) apart that operate at 300 (MHz). Each is equipped with a half-wave dipole.
a) If 100 (W) is transmitted from one station, how much power is received by a matched load at the other station
b) Repeat part (a) assuming that both antennas are Hertzian dipoles.
