AWB3010 Outdoor Antenna

I’m looking for a dual band outdoor external antenna for the Anybus Wireless Gateway (AWB3010). Are there any models you can recommend? I found a 4dBi 2.4/5 GHz Omni MIMO antenna that will work outside, would this work or will the higher antenna gain cause problems?

Thanks

The higher gain antenna should be fine out doors.
@us_sales might have another suggestion for an antenna.
