Abstract: A modular antenna enclosure is disclosed. The modular antenna enclosure includes a frame structure, a base structure including side plates, a capturing member and a frame structure. The frame structure includes vertical support members extending between the capturing member located near the top of the modular antenna enclosure and the side plates of the base structure. Each of the side plates of the base structure is coupled to adjacent side plates via a connector assembly that includes a vertical receptor to receive the vertical support members of the frame structure. The connector assembly can include a securing member that allows users to secure the base structure to a surface below.

Abstract: A highly efficient, multi-stage evaporative air cooler for either residential or commercial applications comprises an internal air pathway traversing an evaporative pad more than once. The cooler comprises an upright free-standing cabinet having an air inlet and a frontal surface through which cooled air is discharged. A rigid cage disposed internally within the cabinet comprises a rigid front plate and a separator plate which divides the cage into separate compartments. The periphery of the cage is completed by a pad support mesh, comprising a grid-like wire wall extending around and between the front plate edges and about the separator plate. An absorbent evaporative pad surrounding the cage adjoins and is supported by the pad support mesh. An internal annular boundary volume defined between the cage and the interior walls of the cabinet establishes fluid flow communication between the separate cage compartments. A fan and a blower motor assembly are secured to the separator plate within the cage.
