In the 400MHz band, the path loss between RWC8201A antennas is about 40dB, and starting decreasing
from 490MHz, it becomes -27dB at 510MHz.
-
In the 900MHz band, which is within the recommended frequency range of RWC8201A antenna, the path
loss is about -21dB and has a flatness of ±1dB within the band.
-
Although the result shows that the loss is larger and the flatness is larger in the 400MHz band than in the
900MHz band, the RWC8201A antenna seems to be good enough to be used in the LoRa Test at the
400MHz band in RWC7100A.
