Can't say how many times I posted on different lists warning about "15 dBi" omnis. It is next to impossible to make a 15 dBi omni with any usable elevation beamwidth at all - electrical downtilt or not. 12 dBi is pretty much the maximum and at that you will be lucky to see anything over a degree on the elevation pattern. Having been in the antenna business before and with a partner who made a career out of designing antennas, I can tell you that we would never use an omni greater than 10 dBi for any application.
