I understand a changing current in a wire gives way to an opposite magnetic field that resists the induced magnetic field, until there is no change in magnetic field, then you're left with a constant induced magnetic field.
So my confusion with the antenna is when an electron rapidly oscillates across the span of the antenna, there would be a rapidly oscillating opposing magnetic response that would nullify the original signal, or at least considerably weaken it.
So how do antenna's operate efficiently?
