ABSTRACT:
A light-weight, collapsible, single or multi element rhombic antenna is disclosed having at least two wire antenna elements for receiving and transmitting electromagnetic waves. The antenna elements are supported in a rhombic shape by an antenna frame. The frame includes four nonconductive legs extending radially outwardly from a center support. At least one of the legs is detachably engaged to the center support. Each leg has a nonconductive cross arm support orthogonally mounted to its outwardly extending end for supporting the antenna wire elements in parallel rhombic formations. An integrated feed network combines the electromagnetic waves. A translation device is coupled to the integrated feed network to convert the electromagnetic waves into a desired output signal. The antenna can be mounted on a mast for either horizontally or vertically polarized operation.
