I see everywhere that with Phantom 4, I can fly about 3KM (3000 meter) , I am in a open area with perfect visibility but after 620 meter I get week signals. My max distance is also disabled. Anyone had similar problem?

Thanks guys.

Aloha Pejvak,

     This result usually happens when there are electrical or telephone cables around.  Is there any kind of tower around?  You can also try the HD option.  Go into HD (upper right) and choose Custom.  Look for the channel with the least amount of interference and choose it.  Set the bitrate slider all the way to the left.

     You might also try Airplane Mode.  If this option helps, there are a few other things that you can do to increase your range.

     Hope this helps!  Let us know how it goes.

Aloha and Drone On!

I would recommend you to check the below video and adjust the antennas.

I only wish I could get that range!

Wow you are lucky to get that range, I am averaging between 1.5KM to 2.0KM
