Marco,
I have included some images of a Az/El rotator system including the
controller in the AMSAT India january Newsletter. I will have more
information in the next news letter on who has built this and other
information.

The U100/110 is what I use as well and its well suited because you can put
the boom right through the rotor.

> Hi Marco,

> If you are looking to lash something together (instead of going with a
purpose-built Elevation rotor), I and others have had success with
Television-type rotors that have a through-hole for the mast. Mounted on
their side, they seem to perform very well. Just keep things balanced, and
protected from the weather and they should be happy.
