Tha tis only necesary for making antenna pattern measurements. Also on
a certified range the ground is made of a consistant material so that
it is uniform over the entire distance between the transmit antenna
and the receiving antenna.

To do a certified range for 30 MHz the test antennae would need to be
separated by ten wavelengths and at least one quarter wavelength in
heigth, preferably higher.
