Make some parabolic reflectors for those too?

I'm exploring this idea, but i don't know very well how to proceed, so:

1. test with wifi extender with standard antennas

2. test with wifi extender with antennas mod 9db in vertical position

3. test with simple plain reflector

I have to calculate S the right distance of the antennas from the corner of the two plain panels.

I have also to calculate the right distance from antenna to antenna. It seems closer than possible.

I'm looking on the web but is not so easy to find the answer. Maybe here there are some engineers that can help

Alfa is the angle. Getting started from 90°, I will check it better solution on the field.

L and H are the dimensions of the panels. Considering that the 9db antenna are 39 cm long,

it will be really large !

That could be a problem on windy days, maybe I have to make them strong and put some weight on my photograpic tripod.

A parabolic reflector could be more complex...
