Best performance will always be obtained with a line-of-sight signal path between the controller and quadcopter – even when the quadcopter is beyond your visual range. Please note: No antenna range extender works well through heavy cover (such as through dense forests) or from behind large solid objects (such as behind hills or large buildings). I’ve tested this DJI Phantom 3 / Inspire 1 Range Extender with my Phantom 3 Pro, and it works amazingly well, delivering substantial additional maximum range. That strategy will ensure maximum antenna gain and the longest possible communications range.
Simply note the position of the green line that appears on your DJI Pilot or DJI GO application map that runs between where you are standing and where the quadcopter is currently located on the map, and turn your controller to face directly up that green line towards the quadcopter. Thanks to DJI, that’s very simple, even when your quadcopter may be out of your direct sight. The only consideration for using this parabolic reflector effectively (and any other high-gain antenna, for that matter) is that you ensure your antenna is squarely facing the quadcopter.
The Range Extender was created using accurate parabolic curves, and with the antenna mounts centered at the parabolic focal points to maximize signal gain. It slips easily onto the standard un-modified DJI Controller Antennas and can be quickly installed or removed with one hand – even when your quadcopter is airborne. This easy-to-print Range Extender will extend the range of your DJI Phantom 3 or DJI Inspire 1 considerably.
