Mount the directional antenna installed with clamp accessories on the antenna
pole: The screw should not be too tight that you are unable to adjust the
direction and the pitch angle of the antenna, nor too loose lest the antenna might
slip downward.
3. Adjusting the azimuth of the antenna
1) Use a compass to determine the azimuth of the antenna. And determine the
installation direction of the directional antenna according to the engineering
design drawing.
2) Turn the antenna slightly to adjust its facing direction, as shown in Fig. 10.4-2.
At the same time measure the direction of the antenna with a compass till the
error is within the engineering design requirements (generally not more than 5
°
).
3) Tighten the fastener 738516 after adjusting the azimuth of the antenna.
