Polar Mast Overview
The ’polar’ mast consists of a lightweight aluminum mast fitted with a custom antenna mount. The mast is bolted with four expansion bolts onto bedrock or cement. Height may vary; shown here is a 1-meter mast, but 0.5-meter and 2-meter masts (e.g. for deep snow or populated areas) have also been produced. This style of mast has been used by the TAMDEF project in Antarctica, the POLENET project in Greenland and Antarctica, and other remote CGPS sites including Mauna Loa, Hawaii.
Design and Construction
A custom jig is used for drilling the bolt holes.
This cost is for the monumentation only.
Mount Commonly Used
The ability to level the antenna and align it to north is included in the design of the polar mast.
