For sale GSSI 200 HS Antenna, Rugged, Wireless Low Frequency 200 MHz GPR System


For sale GSSI 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.

  • Weight: 17.9kg (39.6 lbs)
  • Storage Capacity: SIR 4000: 32 GB
  • Panasonic Toughpad G2: 512 GB
  • Optional Software: RADAN 7
  • Accessories: Wheel kit, GPS mount, Transit case, Survey wheel

Purpose built tools for the Geophysical Industry
The 200 MHz HyperStacking Antenna provides higher resolution data than previously available and greater depths at a lower frequency range.

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.

System Versatility: 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.

Advanced Features: 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.
