MALÅ shielded antennas are primarily used for medium to high resolution surveys. The shielded antenna construction makes the antennas especially suitable for urban investigations or at sites with a lot of background noise. The shielded antennas are modular, with the antenna electronics, pulling handles and measuring wheels being interchangeable between the different antennas. This reduces the cost of ownership and any subsequent system expansion.
MALÅ shielded antennas offer modularity at its best and are very efficient tools for subsurface mapping.
The 100 MHz antenna is the lowest shielded antenna frequency commercially available. It is used for medium to low resolution. Suitable for geological and geotechnical applications.
The shielded 250 MHz antenna is a general purpose antenna. It is used for medium penetration depth and medium resolution. It is commonly used for utility detection, UST and void detection.
The shielded 500 MHz antenna is probably the most popular general purpose GPR antenna ever built. It delivers medium to shallow penetration depth and good resolution. Most commonly used for utility detection and road surveys.
The shielded 800MHz antenna delivers very good resolution for shallow investigations. Commonly used for road mapping and concrete investigations.
