The growth in the number of communication satellites and the increase in antenna signal frequencies places higher demands on the accuracy and mass of reflectors. The accuracy of the reflector depends not only on its structure and materials but is also influenced by its mounting. In this paper, based on the rib-reinforced reflector designed by Bauman Moscow State Technical University, the effect of the reticulated shell mountings with different numbers of interlacing ribs in a shape of a circular truncated cone working in the geosynchronous orbit on the thermal deformation of the reflective surface is investigated by simulations using Siemens NX software. It is concluded that the desired deformation can be obtained when the number of t interlacing is 30. On thermal deformation, the effects of two weight reduction methods, namely reducing the width and thickness of ribs, were also investigated simultaneously. It is shown that reducing the thickness of ribs can achieve the target of mass reduction under the condition of ensuring the accuracy of the reflective surface. It is provided the basis for engineering calculations for practice.
