Abstract
Some calculated results for the input admittance of both insulated and uninsulated drill rods immersed in a lossy medium are given. The source can be either a voltage gap or a thin toroidal coil. For this input admittance calculation the drill rod is assumed to be of infinite length. Even a very thin insulating layer is found to greatly decrease the real part of the input admittance or the input power.
