Due to end effects a finite thickness dipole is not resonant at a length of one-half wavelength but has inductive reactance. A typical thin dipole is actually resonant (has no reactance) at a slightly shorter length of around , at which its radiation resistance is about 67 ohms.Wallace, Richard; Andreasson, Krister (2005).
