#196 In this video I look at how an equivalent electrical model can be created for an antenna. I first look at the basic structure of the electrical model and then I look at some ways in which the parameters for that model can be determined.
Late edit: as correctly pointed out by a viewer, the ideal halfwave dipole impedance is 73+42.5j and resonance is reached when the antenna is slightly shorter, when the impedance is around 70+0j.
