200 HS Antenna
200 HS Antenna
Rugged, Wireless Low Frequency 200 MHz GPR System
GSSI introduces the GS Series, our next-generation family of high-performance antennas targeting applications that require deeper penetration depths. The first antenna in the series is the 200 HS. This digital, wireless antenna 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.

Acquire Data Wirelessly
Identify geophysical characteristics easily with the wireless 200 HS and HS Module. The HS Module connects the SIR 4000 or Panasonic Toughpad G2 to the antenna and allows the user to leverage a single HS Module across all GS Series antennas.
HyperStacking Technology & Improved Depth
The GS Series uses our patented HyperStacking Technology to provide clearer data, from superficial features to deeper characteristics. Our 200 HS antenna achieves greater depth penetration, nearly double than conventional GPR antenna designs.
The GS Series caters to new and existing users with two controller choices; SIR 4000 with a WiFi module, or Panasonic Toughpad tablet. IP 65 rated, the 200 HS antenna can withstand dust and is water resistant.
The GS Series incorporates advanced features designed for survey efficiency including an integrated GPS, and can accommodate an external GPS mount. Visualize data on the tablet with a GIS map mode. Use accessories to customize survey collection modes.

This deep (400+ ns) and detailed stratigraphic section revealed well-stratified glacio-lacustrine deltaic sets overlying likely glacial till and bedrock. This profile demonstrates the exceptional depth penetration of the 200 HS antenna, and also highlights the antenna’s excellent near-surface resolution. Profile from Alton, New Hampshire, USA.
