Hi Ron,

I've done ok on AO-51 with a homemade helix.  See http://home.wavecable.com/~ko6th at the bottom of the page.  I also have watts in the shack, but a full az/el rotor system.  I don't know how sharp the pattern is for the helix, so I don't know how effective a fixed elevation system will be.  But from the reports I've received, the 10 watts and my 60' of hardline with about 7 feet of RG-214 at each end seems to be quite adequate.

Good luck,

Greg  KO6TH
