Safety
Installation of this antenna near power lines is dangerous. For your safety, follow these instructions.
Select your installation site with safety, as well as performance in mind. Remember: electric power lines and
phone lines look alike. For your safety, assume that any overhead line can kill you.
When installing your antenna, remember:
• Do not use a metal ladder.
• Do not work on a wet or windy day.
• Do dress properly—shoes with rubber soles and heels, rubber gloves, long sleeved shirt or jacket.
