2.8 External Connections
The picture (below) depicts the PCB external interfaces.
2.8.1 External Antenna Option
The ST100 has provisions where an external antenna can be used on either the Bluetooth and/or the GPS /
Satellite antennas. If an external antenna is used, care should be taken when connecting the external antenna
to the u.FL connector - Hirose part # U.FL-R-SMT(10) on the ST100 PCB. If this option is desired, Globalstar
needs to know before boards are ordered.
