I agree with this. For example: What should be my best tower is one of my worst because it is quad-sectored. I have a simular tower at another location that is tri-sectored and it performs better than expected. As far as an omni, I use them only where the spectrum is clean, eventually switching to sectors when the subscriber numbers require it. -RickG
