CM375 Portable 10-Meter Mast
1. Overview
The CM375 is a corrosion-resistant 30-ft (10 m) mast for applications requiring a
tall yet portable instrument mount. It consists of five 6-ft (2 m) galvanized pipes,
a stainless-steel base, guy cables, 1 m crossarm and mount, and grounding kit.
Duckbill anchor kits (required) and a guy-wire tensioning kit (recommended) are
ordered separately. All of the components fit inside an 80”-long bag allowing the
CM375 to be carried from site to site (see Figure 1-1).
FIGURE 1-1. 21720 Tote
1.1 Specifications
Weight: 66 lbs (30 kg)
Mast: 30 ft (9.2 m) total length; consists of five 6-ft (1.82 m) sections
Main Mast Diameter: 1.9” (48.26 mm)
Top Section Mast Diameter: 1.74” (44.2 mm)
Base Radius: 20 ft (6 m) to each of three guy points, 120 degrees apart
Guy Configuration: three guy cables at two levels; guyed at 12 ft (3.6 m) and
at 24 ft (7.2 m)
Recommended Guy Wire Pretension: 100 lbs each; check and adjust guy
wire tension at least once a month, and after wind gusts exceeding 50 mph.
Maximum Weight of Mounted Equipment: 75 lbs (34 kg)
Maximum Allowable Wind Gust1:85 mph (136 km h-1)
The wind gust value assumes:
•Proper installation
•Proper anchoring:
oAdequate soil (guy anchors/base support)
oGuy anchors at 20-ft from base with 120 degrees of separation
oProper guy tension (100 lbs each)
•No ice buildup
•Standard air quality or wind assessment configuration (see Table
below)
1The amount of wind gust that this mount can withstand is affected by quality
of anchoring and installation, guy wire tension, soil type, guy angle, and the
number, type, and location of instruments fastened to the CM375.

1.2 Guy Duckbill Anchor Kits
A choice of duckbill anchor kits is offered for the CM375. The 19282 Guy
Duckbill Standard Anchor Kit is for standard soils, and the 25699 Guy
Duckbill Heavy Duty Anchor 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
Both the 19282 and 25699 have one drive rod. The 19282 also has four
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 four duckbill anchors instead of the cable. At the end of the
threaded rod is a metal ring for connecting the guy wires.
