This Demonstration shows the propagation between two antennas of heights
h
1
and
h
2
above ground and the effect of multipath radiation from the ground bounce. The result is multiple nulls or actual fades. It also show the result of adding a diversity antenna of height
ΔZ
above the height
h
1
of antenna 1. It includes the effects of the reflection coefficient from the ground as a function of the angle of incidence and the dielectric constant of earth.
