Hi Sean,
I just want to update you that we’ve added the support of the different antenna handling on the 28 beta 2 firmware version. It means that now Reach RS2 can read the antenna type from the RTCM3 message and add its height to the ARP.
At the moment, the latest available firmware version is the 28 beta 3. It contains this feature as well. So don’t hesitate to try it on your Reach RS2 and share your feedback
