<p>A lens assembly for a window shade radar includes two adjacent membranes (16A,B) rolled onto separate rollers (34A,B). Expandable side masts (20A,B) are pivotally secured to the rollers (34A,B) and the collapsible main beams (33A,B) by slip joints. The main beams (33A,B) enclose wire busses (46,48) which are directly connected to the membrane modular elements (38,42) without interposed rotary connections. <IMAGE></p> |
