The TW-borehole transducers are available with 100, 500 and 1000 MHz center-frequencies, for unlimited applications
37 mm Small Diameter Borehole Radar
Manufactured by RADARTEAM SWEDEN AB
Selection of Borehole Antennas. 100, 500 and 1000 MHz frequency.
General information: The TW-borehole transducers are available with 100, 500 and 1000 MHz center-frequencies, for unlimited applications. They are all fully compatible with GSSI radar systems SIR*. The small diameter probe, only 37 mm, make surveys possible in standard boreholes. The TW-antennas are also waterproof to 20 bars. They can be used both in single boreholes or with a separate transmitter in dual boreholes for tomographic applications.
