Caution:
1. Take careful precautions for the safety of yourself and the equipment during the
whole antenna installation process;
2. When adjusting the antenna that is already working, take certain measures (for
example, wear radiation-shielding clothing), and turn off the high power amplifier to
avoid the direct radiation of the antenna to human body.
10.3.1 Technical Parameters for Antenna Installation
1. Antenna
height
It is determined by network planning.
2. Azimuth of antenna
It is determined by network planning.
3. Pitch angle of antenna
It is determined by network planning. Usually 0° ~ 10° adjustable.
4. Antenna
direction
It is determined by the azimuth of the antenna. Two antennas in the same sector
should point to the same direction.
5. Distance between diversity antennas
The two antennas in the same sector are diversity receiving antenna to each
other with the same vertical height. The horizontal distance (d) is as large as
possible to satisfy the engineering requirements just by following the formula
below.
d
≥
10~20
λ
(or H/d = 11), where d is the horizontal distance between the
diversity antennas, and H is the vertical height from the antenna to the floor. The
diversity distance of the 1900M carrier should be more than 1.5m while that of
the 800M carrier should be more than 3.5m.
10.3.2 Antenna Installation Flow
The antenna installation flow is shown in Fig. 10.3-1.
