Before you start the installation, please read this section very carefully.

Antennas are installed on the roof tops or on the building walls. This work must be accomplished only by personnel having special skills and experience in this area.

Antennas and cables are electric conductors. Incidental electrostatic strikes may occur during the system installation. This can lead to equipment damage or may hurt the personnel. While installing or changing the elements of the antenna-feeder system, one must make sure that open metal parts are temporarily grounded.

Do not install the antenna close to the electric power lines. Antenna and antenna pole have to be installed in such a way that, during their assembling, disassembling and repairing, they do not have any contact with power lines.

Basic precautionary measures that must be fulfilled during the installation are as follows:

• Do not stay on the roof top in windy or rainy weather, during thunderstorms or when the working zone is covered with snow or ice
• Do not touch the antennas, antenna poles, cables and lighting arrestors during thunderstorms
• Antenna cable must be grounded at all times.

In case of failure, any manipulation of the equipment is allowed to trained personnel only.
