The effect of poor ground conductivity is taken care of by installing a ground screen consisting of radial wires extending outward from the antenna base for a distance of
. Such an arrangement is shown in Fig 7.10.

| Fundamentals of Antennas and Radiating systems |
Quarter wave monopole antennas are often used as vehicle mounted antennas, the vehicle providing required ground plane for the antenna. For quarter-wave antennas mounted above earth, the poor conductivity of the soil results in excessive power loss from the induced amount in the soil. |
