A method of aligning a fixture for holding an alignment telescope with an antenna array foundation. In one embodiment, the method includes mounting a fixture for holding an alignment telescope proximate to a first location on an edge of an antenna array foundation, projecting a laser beam outwards from the fixture towards a second location on the edge of the antenna array foundation, and aligning the fixture with the edge at the second location using the laser beam. The fixture may be aligned with the edge of the foundation by adjusting the position of the fixture in relation to the foundation so that the laser beam strikes the foundation edge at the second location, thereby producing a visible laser spot on the edge. The procedure may be repeated to align a plurality of spaced-apart foundation edge locations with the fixture.
