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.

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.
