TD9800-MFC Dual-Frequency Wireless GPR

Two antenna centre frequencies are integrated into a single probe: a high band (400 / 600 / 750 / 900 MHz) and a low band (100 / 200 / 250 MHz). One scan captures shallow small-diameter services and deep large-diameter mains at the same time, and comparing the two bands' data significantly raises pipeline identification confidence.

  • Dual-frequency composite technology in one probe
  • High band 400–900 MHz + low band 100–250 MHz in a single scan
  • Greater effective frequency coverage — depth and resolution in one pass
  • Cross-band data comparison raises identification rate

TD9800-100 MHz Wireless GPR

A 100 MHz centre-frequency radar designed for deep subsurface structures: pipelines, cables, voids and strata interfaces — with detection depth beyond 15 m. Especially valuable for tunnel advance prediction, and a dependable tool for geological engineering, municipal construction and archaeological research. For municipal work we recommend pairing the 100 MHz with a 400 MHz (or 200 MHz) antenna — any dual-frequency combination can be configured on request.

  • 100 MHz band for maximum penetration
  • Detection depth beyond 15 m
  • Tunnel advance (geological) prediction
  • Configurable dual-frequency antenna combinations (e.g. 100 + 400 MHz)
