Utility Mapping GSSI 200 HS Digital Antenna

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.

Wheels may be removed for skid applications such as snow, etc. 

The 200HS requires the use of an external survey wheel if encoded triggering is required. EXI includes a 12" survey wheel with the rental.

The shipped system includes the 200mHz digital antenna, wheels, WIFI module, tow strap and Panasonic G1 Tablet controller. Customers with a SIR4000 may opt to use that for their controller instead of the Tablet for a $30 per day reduction in rental cost.
