CC1310: CC-ANTENNA-DK2: DN038 Antenna Match Network at 920 MHz

Hi 

I notice in the design note  DN038 it says the antenna must be tuned differently for 915/920 MHz. We are looking for a variant for 915-928 MHz. (centered around 922MHz)

Is there any suggested maching or antenna extension to make it optimum for this band?
