On the Modeling of Radio Masts
Radiating towers or radio masts can be modeled in AN-SOF with a high degree of detail, as shown in the figure below. Since we already know the omnidirectional shape of the radiation pattern, what interests us is to calculate electric field values at ground level for a given input power.
The Equivalent Circuit of a Balun
A balun can be implicitly modeled in AN-SOF using an equivalent generator, as the figure below shows. Since voltage sources admit an internal impedance, we can adjust its resistance value to match the antenna input resistance.
