I in my passed life used to assist in putting trackers on wild animals to observe their movements. These devices have gotten down so the is the size of the button batteries used. A suggestion to DJI as these devices could be installed inside of the drones with rechargeable batteries from the main battery and activated when drone is turned on. As the controllers have two antennas it could easily be programmed the go to the frequency and be used as a directional receiver. To increase sensitivity, the signal enhancers sold third parties could be attached to the antennas. The cost to Dji for the new programming feature and the device itself would cost pennies.. Yes they have a limited about 2-3mi range, but most times we know where the last flight signal came from and can start a search in that area. not perfect but drones are getting up there in price and anything would be a help in recovery.
