DJI Phantom 3 & Inspire 1 Range Extender – Version E

cults3d

This version “E” of my original Range Extender (Thingiverse#961197) is a moderate modification, and the primary difference is that the Parabolic Arches on this version are considerably deeper. In general, this makes the ‘focus’ of the Range Extender narrower, or ‘sharper’, while the overall gain is increased. However, this requires the operator to pay close attention to the direction of the quadcopter and to keep the controller and Antennas carefully pointed in its direction. As shown in the photos, this version also fits the Controller very well, with plenty of space to tilt the Antennas and Range Extender to various angles. This easy-to-print Range Extender will extend the range of your Phantom 3 or Inspire 1 considerably. It slips 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 with accurate, deep parabolic curves, and with the antenna mounts centered at each parabolic focal point to maximize signal gain and overall effectiveness. 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 directly facing the quadcopter. Thanks to DJI, that’s pretty easy, 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 range for both control of the quadcopter and transmission of the FPV feed. I’ve tested this DJI Phantom 3 / Inspire 1 Range Extender with my Phantom 3 Pro, and it works very well, delivering considerably more maximum effective range. Please note that 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 you’ll be able to determine 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= 50.75 grams. Please share your Makes and any suggestions you have for improvements.
