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.

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: http://www.rotorservice.com/press3-alliance.htm <- my setup

imitates this one ...

http://home.wavecable.com/~ko6th/ http://users.wbsnet.org/n0yk/cushcraft.htm 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
