Abstract : The terminal-zone effects on the dipole antenna driven by a two-wire transmission line have been re-exa ined. A series inductive correction together with other terminal-zone corrections i found nec ary to reduce t e measured apparent admittance of the antenna termina ing h twowire line with the ideal admittance of the dipole antenna when driven by a delta-function gener-ATOR. The series inductive correction takes account of the absence of the antenna wire in the gap between t e two-wires of the transmission line. With this additional correction, the measured apparent admittance of a dipole antenna may be brought into excellent agreement wi h theoretical values and also reconciled with the quite different values measured with a coaxial line for an antenna consisting of the vertical inner conductor of the line ex end d over a horizontal ground plane.
