Tag and Anchor are 0 degrees facing the same direction, Anchor rotates, Tag does not, cirecles of different colors represent their distance, thier lost communication at some distance and angle.
Does anyone know why there so much lost around 270 degrees
Hi @Malan
I would say that you measurement is too good. The typical real life operational range for DWM1001 with PANS would be about 25m (you need to consider obstacles, NLOS and etc.).
Anchor faces 270 ° while Tag faces 0 °, they lose communication when 30m apart,
I changed their distance, as shown in picture 28m and 32m they did not lose communication.
Re antenna problem) Open space is a tricky environment. First question is what is your open space environment - is it street in the city surrounded by buildings or football field with nothing around? There is a huge difference between them and it is easy to get bad measurement because of reflections. Some time you can get stronger multipath signal than in the direct path. However in your case it seems that it could be affected by Fresnel zones - try to put anchors to 2m or so and recheck it.
