Medium to high power transmitters usually have an extensive ground system consisting of cables buried in the earth under the antenna, to lower resistance. Since for the omnidirectional antennas used on these bands the Earth currents travel radially toward the ground point from all directions, the grounding system usually consists of a radial pattern of buried cables extending outward under the antenna in all directions, connected together to the ground side of the transmitter's feedline at a terminal next to the base of the antenna.
