For a complete and up-to-date list of antennas, open the Antenna.INI file (the default location is C:\Program Files\Common Files\Trimble\Config\antenna.ini) with an ASCII viewer to find antennas by name and their antenna type value. If the Antenna.INI file is not installed, the Configuration Toolbox utility (oemgnss.trimble.com/wpfd_file/configuration-toolbox/) can be installed to load these.
