A system for visually indicating receipt of a radio communication directed to a user having an associated unique identification code. The system includes a radio transponder having an audio output, means for obtaining and storing the unique identification code; a speech recognition circuit operably connected to the radio transponder audio output and the stored identification code; and a visual indicator operably connected to an output of the speech recognition circuit, such that when the stored identification code and said audio input are substantially the same the visual indicator is driven to activation. A method is similarly disclosed.

System and method for visually indicating receipt of a radio communication directed to a uniquely identified vehicle

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.
