GSM shield 2 antenna

Is there a way to add a antenna to a GSM shield 2 with integrated antenna?

thanks

From the illustration it looks like you can add a connector in the five holes adjacent to the integrated antenna. Although I found the integrated antenna superior to other shields with regular antenna.

Google 'SMA PCB connector'.

Thanks alot for the response. My problem is I am trying to send an SMS Message and when running the SMS message sender I get "not connected" over and over. I've tried powering the shield on and off and reseting but get the same results "Not connected". Any Ideas on what could fix this.

I am using GSM shield 2 and arduino uno
