.~ With means for moving directive antenna for scanning, sweeping or orienting {6}
759
.~.~ Spiral motion
DEFINITION
Classification: 343/759
(under subclass 757) Subject matter wherein the directive
antenna is supported for movement of the axis of its beam over a spiral path and wherein the means for moving includes structure which causes the antenna to move its beam axis cyclically over a spiral path.
(1) Note. If the means for moving is such that it only may be manipulated to move the axis of the antenna over a spiral path, as for example, an antenna mounted for azimuthal rotation and nod together with a handle, classification is not here, but in such subclasses as 761 or 765 below. For classification in this subclass, the moving means must be effective to maintain the antenna continuously repeating the same spiral scanning movement.
