The 2.4G RF module is already enabled. Select Internal or External (on ANT1 connector) Antenna. Although the RF stage has built-in protection, it is good practice to ensure that an external antenna has been fitted before selecting the External antenna. Please note that the antenna selection is on a per model basis, so each time a model change selection is made ETHOS sets the antenna mode for the given model.
