   3 sie 2022 · Ground plane antenna online calculator. The GP is the omnidirectional antenna. The calculator takes into account the wire diameter of the monopole and radials. The wire diameter affects the shortening factor of both the quarter-wave vertical monopole and the counterpoises in the same way as in the case of a half-wave dipole.
