CM375 Portable 10-Meter Mast

1. Overview

The CM375 is a corrosion-resistant 10 m (30 ft) mast for applications requiring a

tall yet portable instrument mount. It consists of six 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 a 2 m (80 in) bag allowing the

CM375 to be carried from site to site (see FIGURE 1-1).
