Geoscanners are renowned to provide the best signal and data quality there is to find when it comes to borehole antennas. At the same time the dimensions are kept as low as possible, allowing the use of these antennas in their main field of application like mining, where free space and the size of the borehole might be constricted. The borehole antennas come in three different center frequencies: 100, 500 and 1000GHz to provide a full support for all applications demanding the use of borehole antennas for ground penetrating radar.
