Figure 34.10 shows a Hertz antenna (also known as a half wave antenna, because its length is A/2). The antenna is located far enough from the ground that reflections do not significantly affect its radiation pattern. Most AM radio stations, however, use a Marconi antenna, which consists of the top half of a Hertz antenna. The lower end of this (quarter-wave) antenna is connected to Earth ground, and the ground itself serves as the missing lower half. What are the heights of the Marconi antennas for radio stations broadcasting at?
(a) 560 kHz and
(b) 1 600 kHz?
