Amsterdam: Elsevier Publishing Company, 1967: 196–222. p. 206. The monopole antenna reduced the frequency of the waves compared to the dipole antennas used by Hertz, and radiated vertically polarized radio waves which could travel longer distances.
For example, a vertical monopole antenna requires a ground plane that often consists of an interconnected network of wires running radially away from the base of the antenna for a distance about equal to the height of the antenna.
Because of the close relationship of flow symmetry to the sound field generated, their concept was included here as part of the sound source description (monopole -symmetric and dipole - asymmetric).
Despite these efforts, no magnetic monopole has been observed to date.
Ekpyrotic models avoid the magnetic monopole problem as long as the temperature at the Big Crunch/Big Bang transition remains below the Grand Unified Scale, as this is the temperature required to produce magnetic monopoles in the first place.
