Here’s results of a test of the on-board antenna with transmit power of 3 and channel 26. The test is with the transmitter straight up. The boxplot below shows angles, heights and distance.
It looks like there is some separation between the .25m distance and the others. Again, the power level seems low. A boxplot of the LQI’s for this data.
This graph provides the justification for the LQI for clean data at 100. The clean data makes a better picture than the original, but not good enough, I think.
Maybe more power would help. This graph gets pretty unfocused on the right side.
