Abstract: There is disclosed an apparatus for mounting antennas on a utility pole. The apparatus comprises a group of brackets that encircle the utility pole and support the antennas. Each bracket comprises at least one support arm capable of attaching to an antenna and a faceplate that presses against the surface of the utility pole. The apparatus also includes tightening or closure means, such as nut and bolt assemblies, that connect the brackets together. When tightened, the tightening means draw the brackets encircling the utility pole closer together, thereby pressing the faceplates of each bracket more firmly against the utility pole. This clamps the apparatus tightly in place at selected points on the utility pole.

Abstract: A high efficiency multi-directional airflow system for a telecommunications equipment assembly used for housing electronic apparatuses which facilitate telecommunications functionality. The equipment assembly defines an internal cavity which can be divided into a plurality of air flow channels. Each of the plurality of air flow channels captures a sub-portion of the overall volume provided by the internal cavity. The smaller volume flow channels provide a smaller cross-sectional area through which the majority of air travels. Since the cross-sectional area is smaller, the velocity of the air through the flow channels is increased. Since the air velocity is increased, the heat transfer coefficient is also increased, thus allowing for the more efficient removal of heat from the electronic apparatuses. A set of fan trays can include a plurality of fans each directionally positioned to work in series to cause air to flow through the plurality of flow channels.
