RAMAC/GPR unshielded antennas are low frequency antennas used for applications requiring maximum penetration depths. Where cultural noise is not a factor and the project demands maximum penetration depth MALÅ GeoScience’s unshielded 25, 50, 100 and 200 MHz antennas are the answer.
Antenas RTA
MALA la proud to present: the Rough Terraln Antanna (RTA) series. This series of unique antannas ¡s wollablo In 25 MHz, 50 MHz or 100 MHz varlarrbo. The RTA concept changas tha faca of low-frequency Ground Prenetating Radar (GPR) surveying. The in line all in one, antenna design provides Improved performance for desper penetration. The flexible "snake" like design allows the antenna to be maneuvered basilly end efficiently through the dense or most uneven of terrain without affecting ground contact, providing optimum resutls In the most difficult of enviroments'. The most important benefit belng thet the operator doesn't have to clear en access a path or route prior to the profile or survey.
Antenas HF
Introducing the High Frequency (HF) Shielded Antenna series from MALA; offering the best imaging solution with the highest resolution available. These antennas are primarily used for high precision measurements and surveys, such as Non-Destructive Test (NDT), imaging of concrete and other structure, forensics, road surveys, layer thickness or other applications requiring high resolution measurements and images within near surface, shallow depths.

Borehole radar is based on the same principles as ground penetrating radar systems for surface use, which means that it consists of a radar transmitter and receiver built into separate probes. The probes are connected via an optical cable to a control unit used for time signal generation and data acquisition. The data storage and display unit is normally a Lap Top computer, which is either a stand-alone component or is built into the circuitry of the control unit. Borehole radar instruments can be used in different modes: reflection, crosshole, surface-to-borehole and directional mode. Today’s available systems use centre frequencies from 20 to 250 MHz.
