Hi there, There was discussion about an antenna tracker for the P4 (thread : Antenna tracker for P4 -phantom 4) and I concluded it's worth to test it especially when moving out of LOS behind trees or buildings because of mainly improving penetration. I'm aware that boosters and omni antennas do a good job. However, a serious tracking system with parabolic antennas can't be that wrong... I wrote to dji if they use standard NMEA protocol. No answer yet. So... anybody out there knows?
