SuperAntennaz is an antenna rotator designed for satellite traking.
It can support more than 10kg 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.
Max torque - Min. 60 Nm
Max speed - 30°/s
Weight ~ 5.5kg
Outdorproof - YES

If you are interested by the rotator but not sure about what to buy, I could purpose the following purchase options :
NOT-AVAILABLE RIGHT NOW - Machined parts kit, contains : Machined parts, needed screw and nuts, building instruction. - 219€ + Shipping costs (~20€ for europe)
Kits have been available at some point in the past, but I can't find the time right now to produce some anymore. Machining prices also went high and local supplier was asking for higher order volumes. I can still try to help you at hadji.[myname]@gmail.com.
