question

A communication link between two (\lambda/2) dipole antennas is establishedwith a free space environment. If the transmitter delivers1 (kW) of power to the transmitting antenna, how muchpower will be received by a receiver connected to the receivingdipole 500(km) from the transmitter if the frequency is200(MHz) ? Assume that the path between dipoles is normalto each dipole; i.e., \texttheta = 90°, and the dipoles are aligned.
