We use balanced inputs, so polarity make no sense.
It made sense with single ended inputs (Green and Red), where the outer winding went to ground (a sort of shielding) 
A1-A2, balanced input. A3, ground (for shielding where needed)

Ferrite antennas are right wounded, so the signal is still the same if you rotate it 180°  Wink
