Introduction
SuperAntennaz is an antenna rotator designed for satellite traking.
It can support more than few kgs of antenna, orientate them really fast (close to 30 deg. /s) and in its final version, it is very simple to reproduce. It is therefore perfect to be built, modified, and improved by the community of space HAM enthusiasts all over the world.
