So optimization is required in this aspect. The proposed antenna design uses two sets of drive systems in the elevation axis. This practice has been used in the SMT telescope and the IRAM 30-m antennas. This arrangement is different from a single bull gear or screw type drive system. It could provide an open, accessible receiver space.
Care has to be provided in avoiding the torque which bends the dish structure.
The elevation structure could also be used as a platform for instruments or receivers. The weight estimation of this part is 4000kg. Receiver Space and Arrangement. There are two platforms for receiver mounting. One is at the back of dish sub-structure, and the other is at the elevation structure.
