1. A method of inhibiting rain from wetting a radiating face of a planar array antenna for millimeter wave length communication systems, said planar array antenna for said millimeter wave length communication system being selected from the group consisting of planar array antenna constructed to operate at either at single frequency or at a pair of different frequencies comprising mounting said planar array antenna with its radiating face at an angle α

  • to the horizontal of between 20 and 70° and

    with its radiating face facing downwards toward earth so that it is shielded from rain and rain cannot fall directly onto said radiating face, selecting a radiating angle θ

    for a main beam of said planar array antenna coordinated with said angle α

    to the horizontal to focus said main beam in a selected direction at an elevation angle ω

    to earth so that said radiating face of said antenna radiates upward away from earth and toward a selected target.
