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

Hello,
I'm Marco, IZ5IOW. I'm searching a good and cheap solution to build an * elevation* system to set up an home satellite station. More specifically I'm looking suggestions for the mechanical part... The loading of the antenna is the follow: 15El UHF Yagi and 9 El VHF Yagi. The mechanical part should not bear too much weight!
Can anyone help me?
Thank you all. Best 73s.

Thank you all for the suggestions. I'll check all your indicated solutions. If will be possible I'm going to choose the TV rotors solution...in my opinion is more inexpensive!
Thank you for now!

If you can get the ARRL Satellite Handbook, it shows using 2 TV Rotors (Radio Shack type) for the AZ/EL, with the Elevation rotor turned on its side.
