omni down angle

I'm currently using an omni that has the elevation profile shown in the image. The maximum signal is between 0 and -10 degrees from the horizontal. For the distances between nodes this 5 degree down angle is problematic. It would be ideal if this were exactly 0. I'm having trouble find a an antenna in the 8 - 12 dBi range that radiates horizontal. Can someone recommend a product? -mikeu

band?

You did not say which band you want to use. 

If it is 2.4 GHz then I can suggest the L-Com HG2410DPU

thanks

Yes, I'm looking for 2.4 GHz and that looks like it will work well. Thanks.

Other suggestions would be welcome as I'm shopping around.

ubiquiti

I'm assuming you looked at the ubiquiti omni antennas as well?

I have one for 5GHz at 250ft AGL. It isn't that great at ground level close within 0.5 miles, but at that range I still have plenty of SNR so no real-world problems.

The AMO-2G10 has 4 degree

The AMO-2G10 has 4 degree downtilt and the AMO-2G13 has 2 degree downtilt. With our terrain and the sites where we are installing it would be desirable to have 0 downtilt. -mikeu
