For 315 MHz modules (TCM 300C and TCM 320C) please note that a full approval
is needed if modules are used with external antennas other than the pre-installed
whip antenna.
When using the SMA connector pads please make sure no mechanical forces are
exerted on the 16-pin connector! It is recommended to use a strain relief for that
purpose.
