I recently bought two XBee Series 2 Pros, and I want to increase the range on them. I found an appropriate 2.4GHz antenna with a U.FL connector. I already have one XBee with a U.FL connector and from what I can tell the PCB layout is exactly the same except for the absence of the connector. Would I be able to remove the two wire antennae and solder U.FL connectors on and use them instead?
If the wire antenna is removed, then a soldered uFL connector will allow a functional antenna to be attached.
I would imagine that if you remove the wire antennas first then that should be possible. The answers to these two questions seem to imply that it is possible:
