CM106 Tripod
1. General
The CM106 is a general purpose tripod that can be used for mounting sensors,
solar panels, antennas, and instrument enclosures. The CM106 is constructed
from galvanized steel, with individually adjustable legs that allow installation
over uneven terrain. Height of the mast is 7 ft (2.1 m), or 10 ft (3 m) with the
mast extension.
The CM106 includes lightning and grounding rods, grounding 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, Allowable Wind Speed Specifications). Instrument enclosures
can be purchased with mounting brackets that attach to either the mast or leg
section as shown in Section 5.7.
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.

5. Tripod Installation
5.1 Tripod Base
Tripod installation near power lines is dangerous. The
minimum safe recommended distance from overhead
power lines is 2 times the height of the tripod and mast
combined. Call Blue Stakes to locate buried utilities
prior to installation.
WARNING
The tripod base has three legs, which are individually adjustable, that allow the
tripod to be installed over non-level terrain.
Prepare the area where the tripod will be installed. The tripod requires an area
approximately 9.3 ft (2.8 m) in diameter. Natural vegetation and the ground
surface should be disturbed as little as possible, but brush and tall weeds should
be removed.
Stand the tripod base up on end, and rotate the feet perpendicular to the legs.
Each leg has a slide collar and T-knob with a spring loaded pin that locks into
holes located on the underside of the leg as shown in Figure 5-1.

5.1.1 Mounting on a Relatively Flat Area
Loosen the T-knob and extend each leg until the pin engages in a hole (depress
the tab to disengage the pin from a hole). With the legs extended, orient the
tripod so that one of the legs points South (assuming the instrument enclosure
with -MM Mast Mount bracket will face North). If the instrument enclosure
has the -LM Leg Mount bracket, orient the tripod so that the enclosure will
