What I know we'll need. (2x) RP-SMA Female to MMCX Male Right Angle Cable used to connect the controller to two 900 MHz antennas. (1x) U.FL Mini PCI to RP-SMA Cable used to connect the controller to a 5.8 Ghz antenna. This is all I have for now. Still looking at antennas. What are you thoughts? Boosters? Large antennas for stationary flight (possibly seated and flying mainly in one direction)? Light antennas for mobile flight (able to move around while following drone)? Would you be willing to tear apart your controller? Is flying 3 miles enough?
