Details

Designed for survey-grade positioning, the BT-700B combines a compact housing with a magnetic mount for fast field setup.

Full electrical and mechanical specifications are provided for easy receiver matching and installation planning.

Multi-constellation coverage and stable signal reception help reduce common causes of inaccurate positioning in the field.

Full-band signal support and 360° horizontal coverage help maintain reliable tracking across challenging environments.

Use the model selection guide to choose the right Beitian antenna based on gain, housing material, and mounting method.

A built-in low-noise amplifier (LNA) and wide operating voltage range support stable GNSS signal output.

Mounting and connectivity details include a TNC-K connector, magnetic base, and four M5 screw holes for fixed installs.

Confirm fitment with the dimension drawings before integrating the antenna into vehicles, robots, or survey poles.

Key differences like strict quality control and technical support are highlighted against typical market alternatives.

Common use cases include surveying and mapping, precision agriculture, unmanned vehicle platforms, and marine surveying.
