Section 2. ET Tower Installation

DANGER: Do not install near power lines. If any part of the tower comes in contact with power lines you could be KILLED. Contact local utilities for the location of buried utility lines before digging or driving grounding rods.

CAUTION: Do not fit the 3 meter ET Tower sections together until the appropriate time. Once attached, they cannot be detached.

The ET Tower provides a support structure for mounting the ET101 and ET106 weather station components. Figure 2.1-1 shows a typical ET Tower installation option. The tower is designed to withstand winds of 100 mph. The lightning rod assembly is attached after the instrumentation enclosure is installed (Section 3.1).
