Thanks for the tip. 45degrees will cover both vertical polarization and horizontal polarization too. I have changed the transmitting antennas to vertical polarization so I have all 4 Biquads positioned in vertical polarization (horizontal bow-tie) now.

I did more range test in different urban evironments and here are the results:

I tried your 45degrees, but I changed back to horizontal bow-tie. The reason for not using 45degrees is I got a wider horizontal beam with the horizontal bow-ties. For FPV, I need the horizontal beam to be as wide as possible.

Nice, it has a wide beam (Phi). Do you have the dimensions of it?
