Having seen (I also expericed sometime) many threads/comments/cases about the weak signal between the RC/AC, I am curious about the signal radiation pattern of the AC antenna. If @DJI did simulation or measurement of the RC antenna, could it be possible to publish a polar plot of the RC antenna like this? It would be helpful to adjust the antenna directions to enhance the signal between RC/AC.

I am not sure if they want to publish such info about the techs of the drone ....

There is actually some info in the manual about how to hold your antenna's relative to the AC.
