Geophysical Survey Systems, Inc. 1 GHz Horn Antenna
Model 41000SA
MN30-903 Rev G 7
200 MHz Antenna
The 50200HS HyperStacking antenna has greatly improved resolution performance over previous GSSI
mid-frequency antennas, such as the Model 5106/A (200 MHz). The 50200HS can be used in continuous,
survey wheel or static stacking modes.
