Ground Coupled Antennas / GCB-series

Overview

The ground coupled bowtie GPR antennas from the GCB series have the best performance in their antenna category on the market. The GCB antennas are fully shielded and provide excellent results even in the most EM polluted survey sites anywhere in the world. By implementing sophisticated product and electrical design solutions we succeeded in making all GCB antennas lightweight and compact, superseeding other currently available solutions.

The GCB antennas are produced with a variety of center frequencies allowing you to select the best balance between the required depth of penetration and resolution of the antenna. The center frequency for any of the GCB antennas can easily be determined by simply reading the number value in the name of the antenna. Rigorous quality controls done at the end of the production line at the Geoscanners facility in Sweden take care that all of the antennas outside of the specification are rejected and returned for repair and tuning. In this way we are certain that you can rely on the equipment performance and focus on the survey at hand.
