Ground radials
WebMay 4, 2024 · Radials, as such, are always part of the vertical, ground mounted, antenna. Remember, a dipole has two halves, as the RF signal is being sent up the feed line it changes polarity each 1/2 of the oscillation. In doing so electrostatic and electromagnetic waves flow between the two halves of the antenna, these are what radiates.

WebMay 3, 2010 · The ground plane reacts as the other half of the antenna system to feed the collected radiated frequency/energy back to the xmtr at 180 degrees out of phase to achieve a resonance point with the antenna tuning circuit. This is basic antenna theroy. WebMar 3, 2024 · Ground radials do not need to be resonant. The shorter your antenna, the more you need radials. Elevated radials should be electrically 1/4λ long. Four elevated radials can perform as well as an extensive ground radial system, but a greater number …
