Very cool!

Bart, are these dual pol links or vertical only?  If they are vertical only,
did you try switching to horizontal at your client end?

Generally a single reflection will cause a 90 degree shift in polarization.
Some times over multiple ones you can have some fun things happen that you
can't model.

Also in most cases a passive reflector is only going to be useful if one
station is very close to it with the other being further away.
