DJI Phantom Remote Controller parabolic antenna adapter

DJI Phantom Remote Controller parabolic antenna adapter
Because I'm looking ahead when pilot my Phantom, it's easy to increase distance adding parabolic background to antenna.
Print and put to the inner side sticky aluminium or cuprum foil... :)

EDIT: added newer version and muster for cutting Alu or Cu foiul for this

Today I tried it - flying to loss signal:
without 310m (1017 ft)
with 540m (1771 ft)
