Sector Antenna Recommendation

We currently use the Cambium 90 degree connectorized sector antennas, but at this point with the interference we are seeing we would like to try an antenna that will see less of the horizon. Does anyone have a recommendation for a sector antenna that would be in the ballpark of 30 degrees that they have had success with? Any recommendations are greatly appreciated.

For small spots we use normal panel antennas like Mars DP19.
