The apparent input admittance of an infinitely long, thick monopole driven from a low‐impedance coaxial line is found. The so‐called “capacitive end‐correction” of an antenna driven either by an external delta‐function generator or by an assumed TEM‐mode excitation is then expressed in a very simple form. The theoretical results thus found agree very well with the experimental measurements.
