A half wavelength dipole situated at its center at the origin radiates a time averaged power of 600W at a frequency of 300MHz. A second /2 dipole is placed with its center at a point P (r,,), where r = 200m, = 90 deg, and =40 deg. It is oriented so that its axis is parallel to that of the transmitting antenna. What is the available power at the terminals of the second (receiving) dipole?
