You can remove the little RP-SMA connector and put on a wire antenna if you like. Just make sure you make it the right length for the frequency you're using. Solder the wire to the middle of the 3 antenna pads. Alternatively it should work fine to just solder the wire antenna onto the middle pin of the 3 pin RP-SMA connector where it connects to the board while leaving the connector in place. That will allow you to easily remove it later if you want to use a RP-SMA antenna again.
The prototypes came with wire antennas so I've been flying these radios with a wire antenna for a while, and it certainly works well for small planes. I even used a wire antenna for my 7.6km long range test.
