For 315 MHz and 902 MHz modules (TCM 320C and TCM 320U) please
note that a full radio approval needs to be performed if modules are used
with external antennas other than the pre-installed whip antenna.
For 868 MHz modules (TCM 320) please note that the external antenna
may not exceed 0 dBd antenna gain.
When using the SMA connector pads please make sure no mechanical
forces are exerted on the 16-pin connector! It is highly recommended to
use a strain relief.
