Does the space from the wall to the AirPort Extreme negatively affect WiFi signal?

I am looking to upgrade from a AirPort Extreme (4th gen, "Mac mini"-like profile) which is vertically mounted, to a latest model AirPort Extreme ("tower") and like this vertical mount; however, I thought I had read the WiFi router antenna's should have some "space" (6-12") from the wall, else the signal in that direction will be negatively impacted. Is this true and, if it is, would this mount negatively impact WiFi signal in the direction toward the back of the mount (in other words, would the signal "behind" the front face of the router be negatively impacted?)

The intended placement would be on the eastern most wall, with nothing but a garage beyond it, so the question may be moot as long as the other directions are not negatively impacted.

Any insights would be appreciated, this mount seems like the perfect solution for what I want, pending the answer to this question.

    Yes, though it may not be as big an issue as you say.

    Two issues, the signal would have to pass through the wall, so it would be attenuated. the level of attenuation is hard to say without knowing what kind of wall you are mounting on. I am not up to building codes in your area, but fiberglass insulation may or may not be in the wall between the garage and inside. Either way, if the WiFi signal in the garage is irrelevant, you need not worry about that.

    Second is that the signal would be partially reflected off the wall and may affect MIMO and beam forming operations. Again, without information on the wall composition, It’s hard to say what kind of interference this may cause.
