Abstract

CMR (Cellular Mobile Radiotelephone) equipment is disposed in a configuration that facilitates both transportation to a cell site and, at the site, rapid installation of the CMR equipment and accompanying antenna tower. The CMR equipment incorporates a foundation that includes (i) a rectangular center structure formed from a front horizontal section, a rear horizontal section, a left vertical section, and a right vertical section, and (ii) a nose structure attached to and extending vertically from the front horizontal section. A self-contained CMR equipment edifice, having four walls, a floor and a roof, is secured to the rectangular center structure of the foundation by a plurality of flanges positioned at predetermined locations on the edifice and affixed to both the foundation and walls of the edifice. Several antenna tower sections are attached to the edifice by a number of identical antenna mounting assemblies. Each of the antenna mounting assemblies comprises a bracket attached to a wall of the edifice and a pipe strap removably affixed to the bracket. Left and right crossmember sections are attached to walls of the edifice by the above-mentioned flanges. The left and right crossmember sections are, in turn, respectively secured to top plates of the left vertical and right vertical sections, thereby securing the edifice to the foundation. Left and right leg sections, pivotably attached to opposite ends of the rear horizontal section, are folded into proximity with, respectively, the left vertical section and the right vertical section. In a preferred embodiment, the rear horizontal section includes a left bracket plate pair, disposed at the left end of the rear horizontal section, for accommodating the pivotable attachment of the left leg section. A right bracket plate pair is similarly disposed at a right end for the right leg section.
