A vertical receiving dipole antenna at a position P is 15 km away from a Hertzian dipole antenna that is also placed vertically (see figure below). The receiving antenna measures an E field equal to 10 mV/m.
(a) What is the value of E that the receiving antenna will detect at a height of 3 km above P?
(b) Assuming the receiving antenna can be tilted as it is moved, in what direction must the receiving dipole be oriented in order to obtain a maximum reading?

Calculate the maximum power density 1 km away from a half-wave dipole antenna that is radiating 100 milliwatts. Repeat the calculation for a dipole antenna that is much shorter than a wavelength. (The gain of a half-wave dipole antenna is 2.15 dBi.)
