The Long-Term Evolution (LTE) antenna on the Development Kit (DK) is optimized for global operation, supporting all LTE frequency bands in the region of 698 MHz to 960 MHz and 1710 MHz to 2200 MHz.
All antennas on the nRF9161 DK have fixed matching networks, which means that no matching configuration is needed to switch between the frequency bands. The LTE antenna also supports other frequency ranges, but it is not optimized for operating on these frequency bands.
