Usually the antenna fastening accessories and the angle 
adjustment device accessories have already been installed on 
the antenna under the tower.  

2.  Initial fixing of the directional antenna on the pole  

Attach the directional antenna installed with fixtures onto the 
pole. First do not tighten the screws too tightly to allow easy 
adjustment of the direction and down tilt of the antenna. 
However, the tightness must be high enough to ensure that 
the antenna does not slid downward.  

3.  Adjusting the azimuth of the antenna 

i.  Determine the azimuth of the antenna using a compass. 

And determine the installation direction of the directional 
antenna according to the engineering design drawing;  

ii.  Turn the antenna slightly to adjust its  face direction, as 

shown in  Figure  34. At the same time, measure the 
direction of the antenna with a compass until the error is 
within the engineering design requirements (generally 
not more than 5°);  

iii.  After adjusting the azimuth  of the antenna, tighten 

fastener A;
