Aperture synthesis radio telescopes generate images of celestial bodies fromdata obtained from several radio antennas. Placement of these antennas hasalways been a source of interesting problems. Often, several potentiallycontradictory objectives like good image quality and low infra-structural costhave to be satisfied simultaneously.  In this paper, we propose a general Minimum Variance Method that focuses onobtaining good images in the presence of limiting situations. We show itsversatility and goodness in three different situations: (a) Placing theantennas on the ground to get a target Gaussian UV distribution (b) Staggeringthe construction of a telescope in the event of staggered budgets and (c)Whenever available, using the mobility of antennas to obtain a high degree offault tolerance.
