2, in the horizontal direction position of centre of gravity variation is little under rounding state and the deployed condition, brings like this two benefits:
1) avoid after vehicle (chassis) leveling, position of centre of gravity changes the adverse effect that levelness is caused;
2) antenna equipment often needs to carry out the continuous rotation scanning motion, by the position of articulating point of adjusting each rod member in the linkage position of centre of gravity of antenna equipment is positioned on the centre of gyration line, reduces the moment of inertia of system, increases the stability of a system;
3, can realize simultaneously lifting and two actions of pitching of antenna jib by an actuator, mechanism is simple, and driving element is few, improves the reliability of system;
4, mechanism's overall dimension is compact under the rounding state, and bulk is arranged nervous occasion, is particularly useful for mobile unit;
5, all rod members all adopt articulated form in the mechanism, and the shaft hole matching gap is controlled well, mechanism's good rigidly.
