2. Precautions

FIGURE 1-2. Tripod tote

• READ AND UNDERSTAND the Safety section at the back of this

manual.

• WARNING — Ensure structural integrity during setup and weather

extremes to minimize the chance of damaging the tripod or instruments.
Read all instructions carefully. Once the tripod is in full vertical position,
securely fasten it to the ground using ground spikes.

• WARNING — For installations where soil structure is questionable or the

tripod may experience high wind loads, concrete footings for the tripod
feet and guy anchors should be considered.

• Keep the bottom of the tripod legs free of soil, ice, and debris to prevent

trapping any moisture inside or around the legs.

4. Overview

Tripod Installation Manual Models CM110, CM115, CM120

The tripod (FIGURE 4-1) is constructed from galvanized steel, with
individually adjustable legs that allow installation over uneven terrain.

The tripod includes lightning and ground rods, ground cables, UV resistant
cable ties, and stakes for securing the tripod feet to the ground. A guy kit is
included (optional for the CM110) for sites that experience high wind speeds
(see Section 5, Specifications
with mounting brackets that attach to either the mast or leg section as shown in
Section 6.1.7, Enclosure Attachment

The tripod 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.

(p. 5)). Instrument enclosures can be purchased

(p. 20).

6. Installation

6.1 Tripod Installation

6.1.1 Tripod Base

FIGURE 5-1. 60-degree guy angle

Tripod installation near power lines is dangerous. The
minimum safe recommended distance from overhead
power lines is two times the height of the tripod and
mast combined. Contact local utility providers to locate
any buried utilities prior to installation.

All three models use the same tripod base. Each leg is adjustable, allowing 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. Remove any brush and tall weeds, while
disturbing the ground surface and other natural vegetation as little as possible.

Stand the tripod base 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 6-1.

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 one leg points
away from the equator, or downhill if the tripod is being mounted on a hill. The
tripod is typically plumbed after the mast has been installed, as described in
Section 6.1.2, Mast

(p. 7).

6.1.2 Mast

FIGURE 6-1. 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 142 cm (56 in) long insert with a series
of holes that can be extended to lengthen the mast (FIGURE 6-2). 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 142 cm (56 in) mast section(s) included with the CM115 and
CM120 tripods have a 41 cm (16 in) 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 20 cm (8 in); 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.

FIGURE 6-2. 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 6-3A). 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

6-3B. The pin should be seated in the bottom of the hole when the mast is

upright. Lift the mast up so the pin is in the upper end of the hole to allow the
mast to be tilted down to a horizontal position.

FIGURE 6-3. Mast attachment to tripod base

Secure the mast in the upright position by installing the locking bracket
(FIGURE 6-4A). 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 (FIGURE 6-4B). Install the pin as shown in
FIGURE 6-4C. 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.

The mounting bracket is designed to be under tension when
pressing it into place. If it is not possible to press the bracket into
place, the amount of tension can be reduced by flattening the bend
on the top tab on the bracket by approximately 5° (

FIGURE 6-4A).

Plumb the tripod by adjusting the leg pointing away from the equator and
either of the two remaining legs. With the level on the South side of the mast,
adjust the leg pointing away from the equator for plumb. With the level on the
East side of the mast, adjust one of the other legs for plumb.

6.1.3 Installing the Guy Kit

NOTE

Guy Ring

Guy Wire

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
ring over the mast insert, and attach the guy wires as shown in FIGURE 6-5.
Return the mast to the upright position and install the locking bracket.

Tripod Installation Manual Models CM110, CM115, CM120

FIGURE 6-5. Guy kit

On the end of each guy wire 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 6-6. Loosen the Phillips screw, and remove the
slack in the guy wire by feeding the load end of the guy wire through the
wedge while pulling up on the dead end (FIGURE 6-7).

If the guy line binds inside the case, insert a flat screwdriver into
the window on the case (shown in FIGURE 6-6) and apply
pressure to the guy cinch wedge to free the guy line.

After the slack has been removed from the guy wires, tighten the Phillips
screws and rotate the lever arms to “closed” position to tension the guy wires
(FIGURE 6-6).

6.1.3.1 Guy Duckbill Anchor Kits

NOTE

WARNING

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.

Three duckbill anchor kits are offered for these lightweight tripods. The
duckbill standard anchor kit is for standard soils, the duckbill heavy-duty
anchor kit is for aggressive soils, and the center duckbill anchor kit is used
when additional stability is desired but not required to the same extent as a full
duckbill anchor kit. Aggressive soils have:

• Resistivity less than 3000 ohm-cm

• pH less than 5

• Chloride greater than 1000 ppm

• Sulfate greater than 500 ppm

• Poor aeration

The standard and heavy-duty kits include a drive bar. The center duckbill kit
uses a user-supplied drive bar. The standard anchor kit has three 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 heavy-duty anchor kit 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 center
duckbill anchor has a single anchor with a cable.

Tripod Installation Manual Models CM110, CM115, CM120

The duckbill anchors are driven to the ground at a 60-degree guy angle as
shown in FIGURE 6-8, except for the center duckbill anchor kit, which is
driven straight into the ground directly below the tripod mast. Locate the other
anchor kits on a 2.7 m (8.7 ft) radius for the CM115, or an 3.5 m (11.5 ft)
radius for the CM120 as shown in FIGURE 6-9. Specifications for sustained
wind speed and gust tolerance are given based on guy angle, and the ability of
the anchors to hold at least 1.8 kN (400 lbf).

Duckbill anchors are not suitable for rocky or sandy soils; UTEYE
anchors should be considered for these types of soils.

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 high-lift jack through the loop or metal ring
and jack the anchor up about four inches to rotate the anchor into the load-lock
position.

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.

6.1.3.2 Lowering Mast after Attaching Guy Wires

Once the guy wires have been adjusted, the lever arms can be “opened”
(FIGURE 6-7) and the guy hooks removed to allow the mast to be lowered to
the horizontal position.

6.1.3.3 Center Duckbill Anchor Kit

The Center Duckbill Anchor Kit is used to provide additional stability to the
tripod. By providing an anchor directly under the center of the tripod, it can be
firmly secured to the ground.

FIGURE 6-10. Center Duckbill Anchor Kit

1. Locate the position on the ground directly below the tripod mast. It is

recommended to perform this procedure prior to driving the ground stakes
through the tripod feet. This allows the tripod to be moved to one side to
provide clearance when driving the duckbill anchor into the ground.

2. Insert a steel drive rod into the duckbill and drive the anchor straight down

into the ground using a fence post pounder or sledgehammer until only the
top half of the cable loop remains above ground.

15

Tripod Installation Manual Models CM110, CM115, CM120

3. Attach a high-lift jack to the loop and jack the anchor up about 6 inches to

rotate the anchor into the load-lock position.

4. Move the tripod back into position. Loosen the turnbuckle evenly at both

ends until the hook at the top end can be slipped over one of the leg
mounting bolts at the bottom of the tripod base.

5. Tighten the turnbuckle until the tripod is firmly secured to the anchor.

6. Install the ground spikes in the tripod feet as described in Section 6.1.4,

Staking the Tripod Feet

(p. 17).

16

Tripod Installation Manual Models CM110, CM115, CM120

6.1.4 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 6-11.

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 or even concrete
footings for the tripod feet and guy anchors should be considered.

Keep the bottom of the tripod legs free of soil, ice, and debris to prevent
trapping any moisture inside or around the legs.

FIGURE 6-11. Staking the tripod feet

17

6.1.5 Tripod Grounding

Place the clamp over the ground rod and drive the rod (close to the center of
the tripod) using a sledgehammer or fence post driver. Strip 1.25 cm (0.5 in) 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 6-13.

Mounting brackets covered in this section have U-bolts that attach to vertical
and/or horizontal pipes with the following ranges of outside diameters:

Tripod Installation Manual Models CM110, CM115, CM120

3.8 cm (1.5 in) U-bolt 1.0 – 1.5 25.4 – 38.1 3/4 – 1

5.1 cm (2 in) U-bolt 1.3 – 2.1 33.0 – 53.3 1 – 1 1/2

5.1 cm (2 in) U-bolt
with plastic V-block

Some of the brackets (for example, the CM210) include 3.8 cm and 5.1 cm
(1.5 in and 2 in) U-bolts to extend the range of pipe diameters that the bracket
can accommodate. Brackets with holes for a 3.8 cm (1.5 in) U-bolt will accept
a user-supplied 4.4 cm (1.75 in) U-bolt.

6.2.1 CM210 Crossarm Mounting Kit

CM200 series crossarms include a CM210 bracket as shown in FIGURE 6-17.
The CM210 can be ordered separately to attach a user-supplied pipe (2.5 to

3.8 cm (1.0 to 1.5 in) OD) to a mast or tower leg (2.5 to 5.3 cm (1.0 to 2.1 in)
OD), or to attach a crossarm to two tower legs.

6.2.4 CM230, CM230XL Adjustable Angle Mounting Kits

The CM230 and CM230XL adjustable angle mounting kits (FIGURE 6-20)
allow the user to attach an antenna or sensor and change its mounting angle
from horizonal to vertical. This allows the component being mounted to be
aimed at a specific location. The CM230 is used when mounting the
component close to the mast or tower while the CM230XL extends the
component away from the mast or tower.

FIGURE 6-20. CM230 and CM230XL adjustable angle mounting kits

The CM230 and CM230XL will accept antennas and sensors with an outer
diameter of 2.54 cm to 3.81 cm (1.0 in to 1.5 in). The bracket can be attached
to a mast or pipe with an outer diameter of 3.30 cm to 5.33 cm (1.3 in to

2.1 in). The declination of the antenna or sensor is fixed when the U-bolt
attached to the mast or tower is tightened; the inclination of the antenna or
sensor is then adjusted with the other U-bolt and nuts.

FIGURE 6-21 is an exploded diagram of the CM230XL showing all the
included hardware as well as the curved slots at the end of the bracket used to
adjust the angle of the antenna or sensor.

FIGURE 6-23. CMB200 components

1. Consult FIGURE 6-24 and TABLE 6-1 to determine which brackets are

needed at either end of the brace to attach it to the crossarm and tripod
mast or tower. The figure also indicates what orientation is needed when
the small bracket is used.

Each bracket has a long tab and short tab where the bolts are
attached. The brace arm must be attached to the end with the long
tab.

2. Attach one end of the brace arm to the tripod mast or tower below the

crossarm. Leave the bolts finger-tight.

3. Lift the free end of the brace arm to the crossarm and attach it to the

crossarm. Again, only finger-tighten the bolts.

4. Adjust the position of the brace arm as needed.

5. Fully tighten the two bolts directly connected to the brace arm, and then

tighten the remaining two bolts to clamp the brace arm to the crossarm and
tower or tripod mast.
