1. A cellular communications antenna mast assembly comprising:
a first component having a longitudinal axis and a first profile oriented perpendicular to the longitudinal axis, the first profile formed to include a first recess and a second recess spaced apart from the first recess, the first recess having at least one different dimension than the second recess; and, a second component having a second profile arranged to mate with the first profile so as to co-engage the first component and second component to constrain relative rotation thereof about the longitudinal axis, in which the first profile and the second profile is shaped so as to permit engagement with the first and second recesses of the first profile to align the second component in only one angular position about the longitudinal axis; in which one of the first and second components is connected to a mast component, and the other of the first and second components is connected to an antenna mounting bracket, such that the mast component and antenna mounting bracket are aligned in a predetermined orientation. |
