Xbee Antenna

Hi All,

I have been using Xbee Pro 900s with a wire antennas. Is it possible to remove the wire antennas and solder on SMA lugs to the contact points on the board so I can change to whip antennas? If so, would there be any points that need to be soldered or jumpers installed?

All of the boards appear similar in appearance, however I have not seen a schematic.

Thanks
