A previous memorandum [1] has outlined the advantages of the slant axis antenna for the MMA. Easy receiver access, light weight and small gravity induced deformations are the main advantages over a conventional design. This memo explores a further possible advantage of the slant axis offset design. The use of rectangular panels rather than the conventional pie shaped panels leads to cost savings both in the panels and backing structure. Fewer panels with fewer adjustment points will result in a reduction in labour costs for both panle installation and setting. For the proposed MMA antenna the adoption of rectangular panel reduces the panel count by 23% and the number of joints in the backing structure by 29%. The number of members needed in the backing structure is also reduced.
