CM106 Tripod

1. General

The CM106 is a general purpose tripod that can be used for mounting sensors,
solar panels, antennas, and instrument enclosures (see FIGURE 1-1). The
CM106 is constructed from galvanized steel, with individually adjustable legs
that allow installation over uneven terrain. Height of the mast is 2.1 m (7 ft),
or 3 m (10 ft) with the mast extension.

The CM106 includes lightning and ground rods, ground cables, UV resistant
cable ties, and stakes for securing the tripod feet to the ground. An optional
guy kit is recommended for sites that experience high wind speeds (see Section
2, Specifications). Instrument enclosures can be purchased with mounting
brackets that attach to either the mast or leg section as shown in Section 5.7,
Enclosure Attachment.

The CM106 can be used for a variety of applications. For meteorological
stations, sensors are mounted to the tripod using mounting brackets appropriate
for the model of sensor. For non-meteorological applications, the tripod can be
used to mount instrument enclosures, solar panels, junction boxes, or antennas.
