Several frequencies of GSSI antennas are available for use with the SIR Ground Penetrating Radar (GPR) system. The defining characteristic of these antennas is their operating frequency. The higher the antenna's operating frequency, the smaller the antenna's size and pulse loop, the greater the data resolution, and the shallower the depth-of-penetration. We offer them in either 200, 270, 400, 900, 1500 or 1600 Mhz.
|200 Mhz||$ 50||$ 40||$ 180||$ 700|
|270 Mhz||$ 50||$ 40||$ 180||$ 700|
|400 Mhz||$ 50||$ 40||$ 180||$ 700|
|900 Mhz||$ 50||$ 40||$ 180||$ 700|
|1600 Mhz||$ 75||$ 65||$ 340||$ 950|
200 MHz Antenna
The 200 MHz antenna can be used for applications that require a lower frequency signal to penetrate deep (down to 9 M) for geotechnical applications.
270 MHz Antenna
The 270 MHz Antenna is ideally suited for deeper utility, engineering and geotechnical applications.
400 MHz Antenna
The 400 MHz antenna is ideally suited for shallow (down to 3 m) engineering and environmental applications.
900 MHz Antenna
The 900 MHz antenna is designed for applications requiring shallow penetration down to 1 m (3 ft.), including void detection, concrete thickness assessment and shallow pipe location. It can also be used for location of rebar where space is not limited.
1600 MHz Antenna
The 1600 MHz is a high-resolution, all-purpose antenna used to inspect concrete structures to locate embedded rebar, post tension cables and conduits. It is used on bridge decks for condition assessment and to determine concrete cover.
The Optical cart with the antenna is the only concrete inspection tool on the market with an optical barcode reader and patented Smart Pad technology for easy wall and floor scanning.
