3 sie 2022 · Ground plane antenna online calculator. Created: 03 August 2022. Last Updated: 04 December 2023. Hits: 10696. The GP is the omnidirectional antenna. The calculator takes into account the wire diameter of the monopole and radials.
This calculator is designed to give the vertical length (height) of a quarter wave ground plane antenna, and the length of each of the four radials
Ground Planes. The standard ground plane antenna consists of a vertical radiator which is insulated and centered between 4 horizontal surrounding radials which extend out from the base of the antenna. Each radial is evenly spaced (90 degrees from each other) around the vertical element.
