Hello! I love to fly long range FPV and was wondering which antenna system is better for Phantom 3 Standard's range: ARGtek or DBS? ARGtek modification is simpler and cheaper than DBS modification, but which one, in the end, gives you the most range? I have seen on YouTube 3200 meters for ARGtek, but nothing too impressive for DBS. With ARGtek, could I experiment with different types of antennas because the connectors are outside the controller? Thanks!
Completely Stock Range Over Forest and Houses: 2600feet, lost control signal
Everything Stock Except For Windsurfer Modification Over Forest And Houses: 4000feet, lost video signal
Windsurfer modification over open area with little to no interference: 6600feet, lost video

I just installed the zag
Argtek mod and in most flights have gotten less distance, much less.  I read on one post that this is common for some if not many.  Something to do with a software issue.
