I noticed on my 3 antenna MIMO, I get better SNR by orienting the
antennas in what I would call the L-finger. The center antenna is
vertical, giving the finger. The other two antennas are 90 degrees
offset from each other. Maybe orthogonal-vulgar is a better description.

Most of the photos of these 3 antennas MIMO routers have the side
antennas angled.

The wifi is going to devices with no discernible antenna orientations.
Squeeze devices and phone.

It would be interesting to play with the antenna orientation while
running some jPerf or iPerf throughput tests.
