I've got ten of them all over the place, some pointing one way some pointing another. Sometimes one falls over and dangles whichever way. When I notice I put it back. I've never noticed any difference in sound from any of them no matter which way they're going. Ditto the 5 ft off the floor advice, got some right on the floor they are if anything more effective there than 5ft up.
These things are radiating radio waves. The spiral circuit board trace is the broadcast antenna. Probably if you dig into it enough you will find the radiation pattern is some sort of dipole. Like it matters. The thing is so small that for all intents and purposes the radiation pattern is a sphere. And it don't matter which way you point a sphere.
The effect will of course be stronger closer than farther away. We know this because no matter where Krissy puts hers the cat finds it and curls up right next to it.
