A single inductive loading coil in a vertical or a pair of loading coils in a dipole are commonly used to match a given total antenna length parameter to a given frequency wavelength (where the ratio may not be a nice N/4) for either resonance or low SWR. This question only concerns dipoles with a pair of loading coils or inductors, one in each leg.
If a loading coil is of non-zero dimension and non-zero wire length, then the difference in standing wave current (forward + reverse) would be different across the inductor, which should cause the inductor to radiate a magnetic field (act as a mini loop antenna).
Given this, what should be the relative direction of windings of the two inductive loading coils be for a dipole? Same or opposite winding directions?
Will one winding relationship tend to cancel the (E)M fields and the other constructively add? Or will the directional pattern change?
