A 1-(MHz) uniform current flows in a vertical antenna of length 15 (m). The antenna is a center-fed copper rod having a radius of 2 (cm). Find:
a) the radiation resistance,
b) the radiation efficiency, and
c) the maximum electric field intensity at a distance of 20 (km) if the radiated power of the antenna is 1.6 (kW).
