Control Elements
4.2 Triangular Antennas with shafts
The Gepard GPR utilizes two triangular antennas: a transmitting antenna as well as a receiving antenna.
Both antennas come with a telescopic shaft that contains a rechargeable battery that powers the control unit
of the Gepard GPR.
Transmitting antenna (red marking): The transmitting antenna is generating signals in the range of 60 MHz
to 300 MHz that will be send into the underground.
Receiving antenna (silver marking): The receiving antenna collects all echos and reflections to calculate
potential anomalies that might exist in the underground soil.
Telescopic shafts: The telescopic shafts will be used to mount the antennas to the Gepard GPR as well as
supplying the power to the control unit.
4.3 Charging adapter
The charging adapter, as depicted in figure 4.4, is used to charge the internal batteries of the telescopic
shafts. You can either charge only one of the batteries or two batteries at the same time.
