Abstract
A vertical monopole on shipboard for communication in the very broad band from 1.5 MHz to 30 MHz is analyzed approximately taking into account its location on the upper deck. The current distribution, impedance, far-field pattern, and efficiency of the resistively loaded monopole are determined and compared with the same monopole located directly on the surface of the sea. It is shown that with an input power of the order of 5 kW, an adequate field is maintained near the surface of the sea over the entire frequency band with a reasonably constant driving-point admittance.
