I think that’s unlikely. The highest you usually see in a 90 degree sector is maybe 17-18 dBi. What you gain in horizontal coverage, you give up in either gain or vertical beamwidth, and you really don’t want narrower vertical than the 17 dBi sectors. So for 4x the horizontal coverage, you would expect to give up about 6 dB of gain, so 13 dBi is already impressive. But it is also important to look at the pattern for an omni, some of them have 3 dB or more of variation with azimuth, so an 11 dBi antenna with a nice circular pattern might be just as good as a 13 dBi with an ugly pattern. Different models may also have electrical downtilt, maybe null fill although that seems hard to find in 5 GHz omnis. In general I have not been impressed with any of the 5 GHz dual pol omnis I have tried, they work, but range is nothing to write home about.
