Abstract: A device for adjusting the azimuthal and inclination directions of a wave reflector, notably for Hertzian waves, comprises a base plate adapted to be secured to a reference surface of the reflector, a cradle rigid with the plate and supporting a pivoting element movable in the adjustment inclination plane through an angle readable in relation to the cradle. This movable inclination element supports another element rotatably mounted about an axis perpendicular to the inclination pivoting axis, and constituting an element movable in the azimuthal direction through an angle readable in relation to the inclination movable element.
