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