Our Past, Present and Future: GPR Antennas

The 2600 MHz antenna is an ultra-high resolution antenna used to inspect concrete structures and to locate embedded rebar, post tension cables and conduits. This antenna is compatible with the SIR 4000 and SIR 30 control units.

This 2300 MHz Palm XT antenna offers superior depth penetration and resolution. It features a full keypad control via the antenna top that provides remote control of the user interface. The antenna has seamless software integration with three data collection modes that provide the user with in-field options for data collection – Standard, Cross Polarization and Side Car. The antenna comes standard with a Multi-Positional Survey Wheel which allows users to quickly change between data collection modes. For Palm XT’s manufactured prior to August 2020 an Upgrade Kit is available. The Palm XT antenna is only compatible with the StructureScan Mini XT.

The Palm Antenna offers users the ability to reach tightly spaced areas that were previously inaccessible such as corners, against walls and around obstructions. The antenna includes a dedicated survey wheel, a replaceable skid plate, and removable handle to reduce antenna height, if necessary. The Palm Antenna is compatible with the SIR 4000 and SIR 30 control units.

The 1600 MHz antenna is a high-resolution, all-purpose antenna used on bridge decks for condition assessment, to determine concrete cover and inspect concrete structures. This antenna can see deeper targets while maintaining good target resolution capability. The 1600 MHz antenna is compatible with the SIR 4000 and SIR 30 control units.

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. This antenna is compatible with the SIR 4000 and SIR 30 control units.

The 400 MHz antenna is ideally suited for detection and mapping of utility pipes, void detection, tunnel voids, and archaeological applications. This antenna is compatible with the SIR 4000 and SIR 30 control units.

The 270 MHz antenna is ideally suited for detection and mapping of utility pipes, shallow engineering, environmental applications, and karst investigations. This antenna is compatible with the SIR 4000 and SIR 30 control units.

The 200 MHz antenna is ideally suited for geotechnical and environmental applications, as well as archaeological investigations. This antenna is compatible with the SIR 4000 and SIR 30 control units.

The 100 MHz antenna is used for deep subsurface applications. The 100 MHz monostatic combines the transmit and receive electronics in a single antenna housing, while the 100 MHz bistatic antenna is a versatile antenna pair that can operate in three different configurations to optimize performance. Both antennas are compatible with the SIR 4000 and SIR 30 control units.

The multiple low-frequency antenna is designed for the deepest radar penetration possible. The antenna design consists of interchangeable elements; by changing the length of the antenna, you change the center frequency. This antenna can be deployed in discrete measurements (stacking) or continuous profile data collection modes. This antenna is compatible with the SIR 4000.

The 1 GHz air-launched (horn) antenna is used for pavement thickness and road condition assessment and can be used to collect data at highway speeds with the SIR 30 system.

The 2 GHz air-launched (horn) antenna is a high-resolution GPR antenna used for pavement thickness and road condition assessment. When coupled with the SIR 30 control unit, it can collect data at highway speeds.

Dual Frequency, Smart Antenna
The 300/800 MHz dual-frequency antenna was GSSI’s first digital antenna. The combination of two frequencies allows users to locate targets at depths of up to 5 m (16 ft), ideal for utility, archaeological and environmental surveys. This antenna is compatible with the SIR 4000 control unit and Panasonic G1 controller.

HyperStacking® Technology
The 350 HS is a state-of-the-art digital antenna designed to work seamlessly with GSSI’s SIR 4000 control unit and the G1 controller. It is easily configurable to accommodate a variety of applications including archaeology, geophysics, utility locating, and more. GSSI’s HyperStacking technology greatly improves the depth and data resolution performance over traditional RTS methods.

Wireless, Digital HyperStacking® Technology

The 200 HS is a digital, wireless antenna that features a 200 MHz center frequency and employs GSSI’s proprietary HyperStacking® technology.

This technology improves signal to noise performance and increases depth penetration under all soil conditions. The GS Series is ideal for geophysical, geotechnical, and environmental applications that require high reliability under challenging survey conditions.
