This easy-to-print Range Extender will extend the range of your DJI Phantom 3 or DJI Inspire 1 considerably. 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.
The Range Extender was created using accurate parabolic curves, and with the antenna mounts centered at the parabolic focal points to maximize signal gain.
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. Thanks to DJI, that’s very simple, even when your quadcopter may be out of your direct sight. 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. That strategy will ensure maximum antenna gain and the longest possible communications range.
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. 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). 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. If you pay close attention to the Remote Controller Signal Strength Indicator and the HD Video Link Signal Strength Indicator, you’ll know exactly how strong your signal is, and when you are reaching the limits of your range.
All parts print without support, and require very little post-print finishing. Both the Parabolic Reflector Shell and the Antenna Mounts have been designed to be as thin and lightweight as possible, while still ensuring adequate strength and durability. Total Finished Weight= 49.2grams.
