New to the Phantom.   Was testing the distance sensors on some partially leaved trees and had a crash.  The little doors on one side of the legs popped off and  the leg was bent ever so slightly.  Now I have video problems at maybe 2000 ft. and no signal at 4000 ft. Can anyone tell me with any certianty I damaged one of the antennas.  Is there anyway with software to check their function.  I have relinked the controller.  The video off the sd card is fine.

What are distance sensors ?

I think it would be a lot easier for you to tell us how much damage done , it’s more likely to damage IMU or put it out of sync through your crash, regards antenna you may need to return to dji haven’t heard of any diagnostic tools to check amount of damage.

I would definitely send it in to DJI and them look at it. I am not aware of any software diagnostics for the Phantom that gives you operating status of all the sensors.

You must have been seeing how close to the tree you could get before sensors picked them up.  Small limbs probably weren't detected.

Very true and I should have had the propeller guards on.  Did it right in front of me.

Sorry for the crash, I suggest sending the drone in for diagnose and repair since the drone had crashed. Please fill in the info on the online repair link of our official web and then send it back. Here is the link: https://repair.dji.com/en/SelfRepair/Area
We will do our best to help this out.

The antenna lead has a female spade that most likely has been jarred loose or disconnected all together. I would not fly it until you send it in to be checked.
