Summary

Description
English: Factor by which a half-wave dipole antenna must be shorter than a half wavelength () in order to obtain pure resistive feedpoint impedance (cancellation of reactance). Computed using the induced EMF method as described in Dipole antenna#Induced EMF method. At larger diameters, the approximations used by this method break down, where the graph becomes dashed.
