This paper deals with surface accuracy of satellite mesh antennas. The mesh surface consists of a metallic mesh, a surface cable network, a backup cable network, and tie cables. The mesh surface should be a parabola shape because of electrical performance. Tensile forces of the tie cables give the parabola shape. Values of the tensile force and tensile points affect surface accuracy significantly. So, we derive a relationship between surface error and the tensile forces. Required tensile forces and tensile points are determined to minimize surface error. This method is applied to a simple model. A numerical result shows that this method is effective to improve surface accuracy.
