DJI Phantom 3 & Inspire 1 Range Extender – Version D

cults3d

This easy-to-print Range Extender will significantly extend the range of your Phantom 3 or Inspire 1. It quickly attaches to the standard DJI Controller Antennas, which can be installed or removed with one hand – even when your quadcopter is airborne. Note: This Version "D" has a fairly wide focus, making it easy to use but resulting in slightly lower overall gain than my Version "E" model (Thingiverse #962316). You may want to try both models since they are so easy to print successfully and assemble. The Range Extender was created using accurate parabolic curves, with the antenna mounts centered at the parabolic focal points to maximize signal gain and effectiveness. To use this parabolic reflector effectively, ensure your antenna is directly facing the quadcopter. With DJI's technology, this is simple even when the quadcopter is out of sight. Simply note the position of the green line on your DJI Pilot or DJI GO application map that runs between where you are standing and where the quadcopter is located. Then turn your controller to face directly up that green line towards the quadcopter for maximum antenna gain and longest possible communications range. I've tested this DJI Phantom 3 / Inspire 1 Range Extender with my Phantom 3 Pro, and it works very well, delivering substantially more maximum effective range. Please note that no antenna range extender works well through heavy cover or from behind large solid objects. 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. The Parabolic Reflector Shell and Antenna Mounts have been designed as thin and lightweight as possible while ensuring adequate strength and durability. Total Finished Weight= 49.2 grams.
