EX ANT is a second antenna output from the Crazyflie's radio power amplifier. The intent is to use an external antenna instead of the integrated chip antenna, this could be used to achieve longer range or more directional radiation pattern for example. It is not something that is intended to be useful in normal usage of the Crazyflie.

There is no settings exposed to use the external antenna right now, to use it you would need to recompile and bootload the crazyflie2-nrf-firmware.
