The ideal depth for radials is on the surface of the ground but in the
broadcast industry we normall bury them about 4" (10cm) below the surface.
We have two stations where the radials were buried in excess of a foot
(30.5cm) below the surface. They will work but the efficency of the antenna
will be much worse than if they are on the surface. Of course the amount of
efficiency loss will be related to the soil conductivity in the area of the
antenna. You could see an efficiency reduction of about 10-15% below what
would be realized if the radials are on the surface.
It would be better to install fewer radials on the surface of the ground that
coule be rolled up in the spring of the year or use a wire mesh that could be
rolled out in the fall and removed in the spring. If you could obtain
permission to do this I feel you would be farther ahead than burying the
radials 3' down.
