Improve wifi signal X2

Hi, I have a question regarding the x2 Wi-Fi antenna, how many dbi is the antenna that comes from the factory? and if it were changed to a more powerful one (greater dbi) would it improve the reception of the Wi-Fi signal?

Unfortunately I don’t have a specification for the included antenna. But if you were to add a larger/higher db antenna this may help. Though it really depends on positioning of the other side, as higher db antennas have a narrower vertical angle of transmission/reception.
