Abstract: Systems and methods are provided for cluster matching of contact objects. First and second sub graphs can be generated that include respective first and second subsets of the plurality of contact objects. The sub graphs can be intersected to generate an intersecting set of contact object, which can then be analyzed using one or more processes to determine whether matching objects exist in the intersecting set.

Abstract: Contact objects in one or more databases can be matched using various systems and methods to determine geographical proximity between the objects. Location attributes associated with first and second objects can be compared to determine a distance between the locations associated with the objects. The objects can then be grouped if the distance is less than a threshold distance.

Abstract: A mechanical bracket for mounting a telecommunication antenna on a metallic tower comprises a pipe section to secure the bracket to the tower. The angular position of the pipe section about its longitudinal axis is selected to appropriately orient the bracket. A transversal pivot bridges a pair of spaced apart parallel plates of the bracket. The antenna comprises a pole member with a free end pivotally mounted on the pivot between the two plates. A bolt and nut assembly traverses the pole member and two arcuate slots respectively made in the parallel plates. In operation, the pole member is rotated about the pivot with the bolt sliding in the two arcuate slots, and the bolt and nut assembly is tightened when a desired position for the pole member, and therefore for the antenna, is reached to thereby lock the pole member and the antenna in this position.
