CAUTION

•All installations of any type or size must carry an industry standard and government approved Radiation Hazard Caution label on the feed arm.

•A fenced or roof installation in a commercial, industrial, or institutional environment must carry a Radiation Hazard Caution sign on the access door, gate, or permanently mounted access ladder that is within plain sight of anyone approaching the antenna from the front or sides of the reflector.

Failure to observe these cautions could result in injury to eyes or other personal injury.

Some installations may require additional precautions. See also the HN System Antenna Site Preparation and Mount Installation Guide (1035678-0001).
