Extending Range on your Phantom 2 Vision and Vision Plus
So you've had your Phantom 2 Vision Plus for a little while now and have had a handful of successful flights. Like some, you may be wondering what, if anything, can be done to increase the range of the video feed which is the limiting factor when talking about range and the Vision Plus. With a few modifications you can indeed increase the video range and sometimes by quite a significant amount. Here's an intro as to how to accomplish increased FPV range for your Phantom.
First of all let's go over quickly what the range extender is and what it does:
The range extender does just what the name implies. It receives the 2.4GHz signal from the camera and then transmits that signal to your phone. In order to keep the unit compact and usable on your radio, DJI kept the antennas very small. The antennas are located inside of the unit.
For this particular mod you're only going to need two main additional parts.
Two 2.4GHz WiFi flat panel directional antennas with a RP-SMA connector as well as a pigtail adapter to take it from RP-SMA to UFL mini-PCI which will then connect to the WiFi adapter inside the range extender.
You'll have to get inside the range extender. Inside, you'll see two small grey cables. Those are the stock antennas. Carefully disconnect the grey cables and in their place connect the two new leads (RP-SMA to UFL mini-PCI). That's about as complicated as it gets.
Mount the directional antennas and range extender to a pole or any other clever setup you can think of and that's it!
Should be able to get at least 1000m at which point your radio will be at it's limits and you'll eventually trigger Fail Safe mode.
Remember, that these are DIRECTIONAL antennas. Meaning that they are very much limited to LINE OF SIGHT. Any obstacles will render them next to useless.
It also goes without saying that performing these kinds of mods will void your factory warranty and may also put you in a bit of a grey area when it comes to FAA regulations.
