Yes, I think it could help, though, I think the most important thing would be to keep the fresnel zone at least 60% clear.
I will try to explain how to calculate the area easily without an online calculator.
The equation that you must use is the following:
r=17.32(meters) x √d÷4f
r=72.05(feets) x √d÷4f
where, r=size of the first fresnel zone, d= distance between your antennas (kms) and f= frequency (Ghz).
Therefore, the radius of the first fresnel zone must not be less than the result of your equation
I hope this helps you and I hope I have explained it correctly.
