GSSI 900 MHz Monostatic Antenna For Sale

GSSI 900 MHz Monostatic Antenna

GSSI 900 MHz Monostatic Antenna is a specialised, high-resolution GPR antenna built for near-surface work (up to ~1 m) where fine detail is required rather than deep penetration. It combines portability, a compact size, and compatibility with GSSI’s GPR control units, making it suitable for infrastructure inspection, shallow utility or void detection, and archaeological/forensic investigations. If your application aligns with shallow depth, fine resolution, and potentially built-environment use, it’s a strong choice.

GSSI 900 MHz Monostatic 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.
