1.4. SAFETY FIRST!

Get acquaint with and observe strictly the requirements and instructions of your local legislation. Direct

grounding of the antenna and the tower structure is essential as protection from lightning strikes and static

electricity. The entire earth-connection system must meet your local standard requirements.

Do not install the antenna close to power lines and cables, as their proximity, arc-over or contact with them

during assembly, installation, and exploitation is hazardous and can be lethal.

Do not work alone! You must have at least one assistant always when you work on the antenna. If you have

any doubt concerning the safety, please consult your dealer or engage a professional company.

WARNING!

Expose to strong electromagnetic radiation can result in dangerous maladies or death. Do not allow

people or animals around the antenna during operation and exploitation.
