A parabolic antenna is a concave antenna with a parabolic reflector that receives radio waves sent from geostationary satellites.
The AZ (azimuth) Power Cylinder determines the horizontal angle of the parabolic antenna, and the EL (elevation) Power Cylinder sets the ground angle.
Compared to the conventional (gear) system, the use of Power Cylinder reduces backlash, making the overall manufacturing process easier.
It also allows for a compact design and feedback control ensures reliable positioning.
