1.3 Precautionary Measures
CAUTION
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.
