2.10.4 Installation Procedures
The installation procedures of installing directional antenna on roof show below:
1) Decide the installation direction of the antenna according to the project
installation drawings.
2) Fix the antenna onto the main supporting post. The fixing tightness shall be right
enough for bearing and wind resistance. Looseness may cause loose connection
while too much tension may damage the antenna sheathing.
3) Adjust the azimuth angle of the antenna. Determine the azimuth angle using a
compass according to the engineering design documents . Normally, sector 1 is
in the north. Sector 2 lies in the clockwise 120° direction and sector 3 in the next
