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).
