摘要： A dual mode broadband antenna especially designed to provide an omni-directional low angle or high angle radiation pattern which is predominately horizontally polarized is disclosed herein. This antenna utilizes four wire radiators in the form of an inverted conical log-spiral supported in a vertically extending fashion a predetermined distance above the horizontal ground plane. In order to alternatively operate the antenna in its high and low angle modes, first and second oppositely phased AC currents are applied to the radiators in two different ways using a simple switching device rather than a more complicated network of four hybrid circuits.

摘要： A collapsible apparatus for supporting an antenna or other such device at a predetermined orientation with the horizontal is disclosed herein along with a kit for and method of assembling the apparatus. This apparatus is made up of a number of straight structural members interconnected in a specific way to form a matrix which is movable between a first collapsed position and a second extended position. In this way, with the matrix in its collapsed position, an antenna can be assembled and mounted thereto and thereafter raised to a higher location by moving the matrix to its extended position. When the particular matrix disclosed herein is in its extended position it is combined with three additional structural members to form an octahedron pair for supporting the assembled and mounted antenna.
摘要翻译：本文公开了一种用于以与水平面成预定取向来支撑天线或其它此类设备的可折叠设备以及用于组装该设备的套件和组装方法。该装置由许多以特定方式互连的直的结构构件组成，以形成可在第一折叠位置和第二延伸位置之间移动的矩阵。以这种方式，当矩阵处于其折叠位置时，可以将天线组装并安装到其上，然后通过将矩阵移动到其延伸位置而升高到更高的位置。当本文公开的特定矩阵处于其延伸位置时，其与三个额外的结构构件组合以形成用于支撑组装和安装的天线的八面体对。
