Antenna type of Galaxy South G7 for postprocessing

Hi, we are now working with the South Galaxy G7 to establish base points in Ethiopia. We want to upload the data for postprocessing to Auspos and then need to state the antenna type. I cannot find this in the manuals of the device. Would it be possible to supply me with this information or tell me where I can find it?
Regards,
