I agree on TV rotors. Its an excellent inexpensive way to get elevation. The
U100/110 is what I use as well and its well suited because you can put the
boom right through the rotor.
There are some nice pictures of setups using these rotors on this sites:

this one ...

And there?s a QST article on this in the Dec 1998 issue
You can even build a controller for computer control but I?m currently
rotating elevation and azimuth manually.

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.
See: http://home.wavecable.com/~ko6th/
I used an Alliance U-110. It has performed flawlessly for about 10 years now.
Good luck,
Greg KO6TH
