5. Tripod Installation
5.1 Tripod Base
WARNING
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.
All three models of tripods use the same tripod base. Each leg is adjustable,
which allows the tripod to be adjusted for non-level terrain.
Prepare the area where the tripod will be installed. The tripod requires an area
approximately 7 feet 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.
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 the open
channel of the tripod base faces North. The tripod is typically plumbed after
the mast has been installed, as described in Section 5.2.

FIGURE 5-1. Tripod Leg, Slide Collar Components
The CM110, CM115 and CM120 tripods have one, two or three mast sections
respectively. The top mast section has a 48” long insert with a series of holes
that can be extended to lengthen the mast. Remove the bolt that secures the
insert to the inside of the mast, and slide the insert out from the mast to see the
different hole locations. Slide the insert back into the mast, aligning the
appropriate holes of the insert with holes in the mast, and replace the bolt.
Additional 56” mast section(s) included with the CM115 and CM120 tripods
have a 16” long insert that is used to connect the mast sections together.
Remove the bolt that secures the insert to the inside of the mast and extend the
insert 8”. Align the holes and replace the bolt. Attach additional mast sections
by sliding the bottom of the next mast section over the insert of a lower section,
aligning the holes and installing the bolt. Typically the bottom mast section is
attached to the tripod and tilted down to a horizontal position, and the
additional mast sections bolted to the bottom section.

Mast
FIGURE 5-2. Tripod Mast and Insert
The tripod base has two sets of right-angled holes for attaching the mast;
typically the lower set is used (Figure 5-3A). The mast is attached to the base
with a pin, and secured in the upright position with a locking bracket. Both the
pin and the locking bracket are secured with a lanyard.
To attach the lower mast section, hold the mast upright and align the hole in the
bottom of the mast with the holes in the tripod base. Insert the pin through the
holes, and rotate the wire retainer over the end of the pin as shown in Figure
5-3B. The pin should be seated in the bottom of the hole when the mast is
upright. Lift the mast up so that the pin is in the upper end of the hole to allow
the mast to be tilted down to a horizontal position.

FIGURE 5-3. Mast Attachment to Tripod Base
Secure the mast in the upright position by installing the locking bracket (Figure
5-4A). Insert the top of the bracket into the notches in the tripod base, and
using both thumbs, press the bracket into the body of the base until the lower
tabs lock into position. Install the pin as shown in Figure 5-4C. To remove the
bracket, remove the pin and squeeze the lower part of the bracket to disengage
the tabs, then rotate the bracket out and up.
Plumb the tripod by adjusting the northeast and south facing legs. With a level
on the East side of the mast, adjust the Northeast leg for plumb. With the level
on the South side of the mast, adjust the South leg for plumb.

5.3 Installing the Guy Kit
The CM115 and CM120 tripods include a guy kit; the guy kit is an option for
the CM110. With the mast tilted down in the horizontal position, install the
guy collar over the mast insert, and attach the guy wires as shown in Figure
5-5. Return the mast to the upright position and install the locking bracket.

FIGURE 5-5. Guy Collar
On the end of each guy line is a case consisting of a hook, clamp, and lever
arm. Rotate the lever arm to the “open” position, and attach the hook to the
tripod leg as shown in Figure 5-6. Loosen the Phillips screw, and remove the
slack in the guy line by feeding the load end of the guy wire through the wedge
while pulling up on the dead end (Figure 5-7).
After the slack has been removed from the guy lines, tighten the Phillips
screws and rotate the lever arms to “closed” position to tension the guy lines.

5.3.1 Guy Duckbill Anchor Kits
Duckbill anchors are recommended for areas subjected to higher winds. They
allow the guy wires to be anchored at points beyond the feet, thereby
increasing the rating of the tripod for higher winds.
Two duckbill anchor kits are offered for these lightweight tripods. The 19282
Guy Duckbill Standard Anchor Kit is for standard soils, and the 25699 Guy
Duckbill Heavy Duty Kit is for aggressive soils. Aggressive soils have:
• Resistivity of less than 3000 ohm-cm
• pH of less than 5
• Chloride of greater than 1000 ppm
• Sulfate of greater than 500 ppm
• Poor aeration
The 19282 and 25699 have their own drive bar. The 19282 also has thr ee
duckbill anchors with a cable attached to each of them. At the end of the cable
is a loop for connecting the guy wires. The 25699 has a threaded rod attached
to each of the three duckbill anchors instead of the cable. At the end of the
threaded rod is a metal ring for connecting the guy wires.
The duckbill anchors are driven to the ground at a 60-degree guy angle as
shown in Figure 5-8. Locate the anchors on a 7.5’ radius for the CM115, or a
10’ radius for the CM120 as shown in Figure 5-9. Specifications for sustained
wind speed and gust tolerance are given based on guy angle, and the ability of
the anchors to hold at least 400 lbf.
NOTE
Dukbill anchors are not suitable for rocky or sandy soils; the
UTEYE anchors should be considered for these types of soils.
11
Tripod Installation Manual Models CM110, CM115, CM120
r
r
It is important that the anchors be driven at the same angle as the guy wires.
Insert the drive bar into the anchor body and drive the anchor into the ground
using a sledgehammer until only the top half of the loop or metal ring remains
above the ground. Place a bar or highlift jack through the loop or metal ring
and jack the anchor up about four inches to rotate the an chor into the load-lock
position.
WARNING
Failure to install and lock the anchor at the correct
angle will result in the anchor cable cutting through
the soil until the angles equalize, causing slack

5.4 Staking the Tripod Feet
Six stakes are provided for securing the tripod feet to the ground. Drive two
stakes through holes in each foot at an angle as shown in Figure 5-10.
Stakes may not be adequate depending on soil structure, maximum wind
speeds experienced at the site, mast height, or wind load from the
instrumentation. For questionable situations, additional stakes (PN 17049) or
even concrete footings for the tripod feet and guy anchors should be
considered.
FIGURE 5-10. Staking the Tripod Feet

5.5 Tripod Grounding
Place the clamp over the ground rod and drive the rod (close to the center of
the tripod) using a sledge hammer or fence post driver. Strip 1/2” inch of
insulation from both ends of the black 4 AWG ground wire. Insert one end of
the ground wire between the clamp and ground rod and tighten the bolt on the
clamp. Attach the other end of the ground wire to the lug on the tripod base as
shown in Figure 5-12.

Attach the CM202 (2 ft, 0.6m), CM204 (4 ft, 1.2m), or CM206 (6 ft, 1.8m)
crossarm to the tripod mast as shown in Figure 5-13. For wind sensors, the
crossarm should be approximately 103 inches above the ground for a 3m
mounting height, or 64 inches for a 2m mounting height. Typically the
crossarm is oriented East/West for wind sensors, North/South for
pyranometers.
