Abstract
Abstract This invention is a collapsible two element cubical quad antenna consisting of two separate four member antenna elements. One end portion of each antenna element converges at a vertex and the other end portion of the antenna element describes a square. The axis of the vertex of one antenna element is positioned opposite to the axis of the vertex of the other antenna element. Thus, the end portions of both antenna elements, as positioned, describe a cubical figure. The end portion of both antenna elements serve as support points for antenna wires.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
154 words
A collapsible antenna array comprising, in combination: a support member; a pair of first support spreader arms and a pair of first rotatable spreader arms converging at a first vertex, said pair of first rotatable spreader arms rotatably attached to said support member by support means; a pair of second support spreader arms and a pair of second rotatable spreader arms converging at a second vertex, said pair of second rotatable spreader arms rotatably attached to said support member by support means; pivot means for rotatably attaching said first support spreader arms to said second support spreader arms; vertex attaching means coupling said first vertex and coupling said second vertex; antenna attaching means coupling an antenna to the end portion of said first support spreader arms, said first rotatable spreader arms, said second support spereader arms, and said second rotatable spreader arms to form a cubical array; antenna lead wires attached to said antenna.
Claim 2
Dependent Claim
154 words
