Up for sale I have a DJI 900mhz Data-link. This is the REAL DEAL, this is not the same as the wimpy 2.4ghz datalink. It is much higher power that the 2.4 Data-link & because of the lower frequency it has much better object penetration and increased range. I have used this with my Phantom2 vision+ to go out as far as 4 miles, at which point I was running out of power to make the round trip but still had data connection. This was done sitting inside my house in a rather populated area!! Properly setup outdoors, I can't imagine you every exceeding the range of this setup before you run out of battery. Also included but not pictured is a cable to connect this directly to the Canbus port on a phantom2 main board & a set of custom 900mhz CP Cloverleaf Antennas(the antennas are pretty BIG at this frequency, just FYI) I will try and get some pictures of those posted up later This Data-link is for the PC app only, it does not work with the iPad app.
