Description: Radials and radial rings. This category describes radials and radial rings for ham radio antennas. Vertical antennas are ideally equivalent (electrically speaking) to one half of a dipole antenna stood on its end. That is, half of the dipole is the vertical antenna itself and the other half is the ground plane under the antenna.
Ham radio installations often have to deal with poor ground conductivity - for example, in an installation on a rocky hill. In order to increase the efficiency and overall effectiveness of your antenna system, improvements to the underlying ground plane can be made. Radial wires are wires places below the vertical antenna which aid in reducing return losses. Radial rings are used to tie many radials to a common point at the base of the vertical antenna.
