A YouTube showed up recently showing the removal of the two internal antennas on the DJI RC and installing external antennas. The purpose was to help with the range issues being reported on the Mini 3 Pro. Aside from voiding any warranties I feel this will improve the range regardless of any firmware updates that will also improve range. I imagine the antennas on this controller were put inside for appearances sake but for those who prefer function over form it seems to be a no-brainer. I suppose it is possible that these internal antennas may be of a special design the does in fact provide the same or greater level of performance as any external antennas but I would need to see the technical report and data before I believe it.
