Details

Choose the BT-M110SLD magnetic base for quick, stable RTK antenna mounting on metal surfaces, with a standard 5/8"-11UNC thread.

A magnetic base mount helps keep an RTK antenna steady on vehicles and equipment used in surveying, construction, and precision agriculture.

Other compatible base models are available in the same 5/8"-11UNC thread standard for different size and pull-force requirements.

Dimensional drawings help confirm fitment for your GNSS antenna mast or adapter before selecting screw length.

An aluminum-alloy screw structure is designed for durable, repeatable mounting in demanding field environments.

Built for outdoor positioning work where wet weather and vibration are common.

Select from magnetic, bolted, or 3M tape + flange fixation styles depending on your installation surface.


The BT-M110SLD option provides a magnetic mounting base with a threaded screw interface for secure GNSS RTK antenna setups.

A roof-mounted magnetic base makes it easy to deploy and remove GNSS antennas on vehicles during testing and surveys.

Each order includes one optional base set configured to the model and mounting style selected.
