CM375

The CM375 is a corrosion-resistant 10 m (30 ft) mast for applications requiring a tall yet portable instrument mount. It can support sensors, an environmental enclosure, a solar panel, and an antenna. Sensors are attached to the CM375 mast via mounts such as the CM202, CM204, and CM206 crossarms. To reinforce the mount, the CM375 is guyed at 3.7 m (12 ft) and 7.3 m (24 ft) heights. Duck-bill anchors and the guy-wire tensioning kit ensure proper guying.

The CM375 comes with five 2 m (6.56 ft) galvanized pipes, a stainless-steel base, guy cables, a 1 m (3.3 ft) crossarm, and a mounting bracket. An anchor kit is required; standard and heavy-duty anchor kits are offered as Common Accessories (see Ordering Info). A guy tensioning kit is also available as a Common Accessory.

A 2 m (80 in) bag is included with the CM375; all of the CM375's components fit inside the bag, allowing the CM375 to be carried from site to site.

Guy Duckbill Anchor Kits

Two duckbill anchor kits are offered as common accessories (see Ordering Information). The 19282 Guy Duckbill Standard Anchor Kit is adequate for most sandy and loamy soils.

Clay soils and other soils with higher corrosive properties will require the 25699 Guy Duckbill Heavy Duty Anchor Kit. These corrosive soils, also known as aggressive soils, have one or more of the following properties:

• High electrical conductivity (> 0.33 dS m^-1)
• High acidity (pH < 5)
• High chloride concentration (> 1000 ppm)
• High sulfate concentration (> 500 ppm)
• Poor aeration
