Abstract : Alignment of the optical, mechanical and electrical axes of an antenna system is accomplished at short range by means of a test antenna having an aperture that is approximately 20 percent greater than the aperture of the antenna being aligned. The test antenna is positioned to receive or transmit radiation from/to the antenna being aligned at a distance of less than D sq/lamda where D is the diameter of the antenna aperture and Lamda is the wavelength of the antenna operating frequency.
