Maximum gain antenna that can be used with Xbee XSC S3B?

I want to use a 13 dBi antenna for my Xbee but I am not sure if the xbee could support that antenna or not.

Assuming that you are in the US, here is the page from the manual on FCC certified antennas:

It looks like a 13 dBi antenna will require a certain amount of cable loss to be legal under FCC restrictions.

As to whether the XBee can physically support it, the answer is yes.
