Hi all,

To clarify this for myself quick question about external antenna patterns from data sheet and actual antenna positions.

Are antenna positions right in image below? First two patterns creates 3D pattern and third one is pattern for 90deg tilted antenna..

(I think "Antenna from top" needs to be rotated by 90 degrees?)

The antenna picture in the vertical/90 plot is wrong. Instead of rotating the antenna 90 degrees clockwise relative to the vertical/0 one, the antenna should have been rotated 90 degrees around its vertical axis (so we'd be looking at the flat side of the antenna). And you're right, for the top view the red rectangle should be rotated 90 degrees, such that the max gain is in the direction perpendiular to the flat side of the antenna (sideways).
