HF Shielded Antennas
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. These antennas offer a reliable and non-destructive way of gathering subsurface information accurately, efficiently and in real time, for both metallic and non-metallic features such as rebar, conduits, wiring, plastic pipes, post-tension cables, voids and more. The 1.2 GHz and 1.6 GHz antennas are also available with a built-in, fully integrated 50/60 Hz sensor to aid in the detection and location of energized cables and conduits within the structure under investigation. MALÅ was the first GPR manufacturer to offer this unique combination which can provide an extra measure of safety to any project.
Brief Description & Technical Specification
MALÅ’s range of shielded HF antennas is fully compatible with both the CX Concrete Imaging System and the ProEx radar control unit. These antennas are small and light-weight enabling hand-held surveys. They can also be fitted to mini-carts or road survey carts.
1.2 GHz
The shielded 1.2 GHz HF antenna is a high resolution antenna used for high quality radar measurements, with the deepest penetration in the HF range. An optional EM sensor enables the detection of radiating 50/60 Hz fields from power cables and/ or other metallic conductors within the structure under investigation.
Dimensions : 190 x 115 x 110 mm – Weight: 1.0 kg
(1.2 kg with 50/60 Hz sensor option)
1.6 GHz
The shielded 1.6 GHz HF antenna is a high resolution antenna used for high quality radar measurements, with medium penetration in the HF range. An optional EM sensor enables the detection of radiating 50/ 60 Hz fields from power cables and/ or other metallic conductors within the structure under investigation.
Dimensions : 160 x 90 x 110 mm – Weight: 0.6 kg
(1.2 kg with 50/60 Hz sensor option)
2.3 GHz
The shielded 2.3GHz antenna is a high resolution antenna used for high quality radar measurements, with shallow penetration in the HF range.
Dimensions : 160 x 90 x 110 mm – Weight: 0.6 kg
Applications: Concrete, reinforcement studies, road mapping and quality assurance.
