DJI Phantom 3 & Inspire 1 Range Extender – Version D

thingiverse

This easy-to-print Range Extender significantly boosts the range of your Phantom 3 or Inspire 1. It securely clips onto standard un-modified DJI Controller Antennas and can be quickly installed or removed with one hand, even while your quadcopter is airborne. Note: This Version "D" has a fairly wide 'focus' that makes it easy to use but results in a slightly lower overall gain than my Version "E" model (Thingiverse #962316). They are so easy to print and assemble that you may want to try both of them. The Range Extender was created using precise parabolic curves, with the antenna mounts centered at the parabolic focal points to maximize signal gain and effectiveness. For optimal use, ensure your antenna is directly facing the quadcopter. Thanks to DJI, this is easily done even when out of direct sight. Simply note the position of the green line on your DJI Pilot or DJI GO application map 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. This strategy ensures 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 very well, delivering substantially more maximum effective range. Please note that no antenna range extender performs well through heavy cover or behind large solid objects. Best performance is always obtained with a line-of-sight signal path between the controller and quadcopter – even when beyond visual range. If you pay close attention to the Remote Controller Signal Strength Indicator and HD Video Link Signal Strength Indicator, you'll know exactly how strong your signal is and when you're 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.
