•
Internal/External Antenna
The internal antenna option uses a LoRa antenna that is located within
the enclosure of the logger. This setup is generally suitable for
environments where the distance and physical barriers between the
logger and the gateway are minimal.
The external antenna option includes a female RP-SMA connector that
allows for a LoRa antenna to be attached further away from the logger
unit. This feature is particularly beneficial for increasing signal strength
and is ideal for use in challenging environments where the logger is
placed in locations that are difficult to reach or are outside the effective
radio range of the internal antenna.
