Antennas

MALÅ’s range of High Frequency (HF) Shielded Antennas offers 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, forensics, road surveys, layer thickness or other applications requiring high resolution measurements and images. 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.

Three High Frequency (HF) antennas are now available at frequencies of 1.2 GHz, 1.6 GHz and the new 2.3 GHz. This range allows the user to pick the most suitable antenna for their high frequency application and offers the choice of maximum signal penetration to highest resolution for the given application.

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.

All of the standard (non-EM) HF Shielded Antennas are fully compatible with the CX and CUII (with High Frequency Module) control units, XV Monitor and Ground Vision data acquisition software. Only the CX Series currently supports the EM variants.

Data collection is fast and simple using the integrated start/stop buttons, particularly when combined with the single "push/turn" button on the XV Monitor with its dedicated easy to use software. The user can quickly scan an area and display data in single scans or 2.5D grid projects for immediate on site analysis and review.

1.2 GHz with EM The 1.2 GHz with EM antenna is a high resolution antenna used for high quality radar measurements, with the deepest penetration in the HF range. It is commonly used for concrete, reinforcement studies and for road mapping and quality assurance.

1.6 GHz The 1.6 GHz antenna is a high resolution antenna used for high quality radar measurements, with medium penetration in the HF range. It is commonly used for concrete, reinforcement studies and for road mapping and quality assurance.

2.3 GHz The 2.3 GHz antenna is a high resolution antenna used for the high quality radar measurements; it offers the highest resolution for shallow investigations in the HF range. It is commonly used for concrete, reinforcement studies and for road mapping and quality assurance.

1.6 GHz with EM The 1.6 GHz with EM antenna is a high resolution antenna used for high quality radar measurements, with medium penetration in the HF range. It is commonly used for concrete, reinforcement studies and for road mapping and quality assurance.

1.2 GHz The 1.2 GHz antenna is a high resolution antenna used for high quality radar measurements, with the deepest penetration in the HF range. It is commonly used for concrete, reinforcement studies and for road mapping and quality assurance.
