Normally for side-mounting on a normal tower, one wavelength will get you close to an omni pattern, but something as big as a water tower, I don't know. I don't think you'll be able to mount it far enough away, practically speaking. I'd still mount it facing towards the most important area to cover from that site, and vote it. -- Jim Barbour WD8CHL
