Tower sector frame antenna mount

Abstract

An improvement for an aluminum lattice sector frame of the type used for supporting wireless communications antennas and designed to be mounted on a communication tower, is provided. Mating extruded components are used to provide fixed connections which restrict relative rotation and translation between connected parts while presenting a round tubular outside cross-sectional profile thereby reducing the effective projected wind load area of the frame. The fixed component connections greatly reduce the overall deflection of the frame under applied combined dead, wind and ice loading.
