My project needs a lot more range and I was wondering if I could desolder the whip antennas of the Xbee and solder on ufl connectors. I'm aware that xbees do come out of the box with ufl connectors but sadly they aren't available where I'm from and my deadline won't allow me to order online.
I was wondering if I could switch out the whip antenna and attach ufl connectors to use these following antennas. Xbee is 2.4Ghz

2)Duck antenna (with a ufl to Rp-sma converter ofcourse) - https://www.sparkfun.com/products/558
