improve performance and are there supplied with two stub
antennas. One of these should be fitted to this connector and the
other to the ANT. (AUX) connector.
Note: Small stub antennas are provided as standard but a range
of suitable alternative for use in different applications may be
purchased separately.

second antenna supplied with the unit. On models that do not
support diversity antennas this connector will not be present.
