ABSTRACT:
A dual polarized cross notch array employing a positioner for locating and grounding metallized portions of unrestrained element ends with respect to metallized restrained element ends. The positioner is a planar member having spaced rows and slots in intersecting rows and columns. Conductive tabs are formed adjacent to the slots at the intersections of the rows and columns corresponding to intersections of the element ends. The conductive tabs receive corresponding portions of the intersecting element ends in secure mechanical engagement and electrical contact. The positioner maintains the polarized elements rigidly in orthogonal configuration. In alternative embodiment employs conductive members preferably formed of tape at the inside corners of the array. Improved radiator elements and a positioner for preconfiguring the array is also disclosed.
