2) Connect the jumper connector to the antenna connector and fasten it.
3) Perform waterproof and sealing treatment to the joint between the antenna and
the jumper. Please refer to Section 2.3.6 for the waterproof treatment.
& Note:
Steps 2) and 3) can be completed on the tower or the building-top.
3.2.2 Installing Directional Antenna Accessories
Accessories used to assemble the directional antenna are antenna fixing clip (as
shown in Figure 3-5), tilt angleadjustment device (as shown in Figure 3-6), and jumper.

The installation procedure of accessories is as follows:
1) First, determine the two fixed adjusting points on the top and bottom of the
antenna according to the label on the back of the antenna. The point on the top of
the antenna is for adjusting the pitch angle, and the point on the bottom for fixing
the antenna and its support.
2) Mount each accessory to its position according to the assembly diagram provided
by the vendor. All the accessories must be furnished with spring washers and plain
washers.
3) Jumper connection: Take off the jacket at the lower part of the antenna. Then
connect the jumper connector and the antenna connector and fasten them.
4) Perform waterproof treatment to the connector (the same method as that to the
connector between omni antenna and jumper).

Caution:
Antenna fixing clip and pitch angle adjustment device must be furnished with spring washers and plain
washers in correct installation sequence.
3.3 Installing Grounding Bar
Grounding copper bar is used to connect the PGND and working ground of the cabinet.
It should be installed both indoor and outdoor. In indoor installation, it is usually
mounted on the wall near the BTS; while in outdoor installation, it is usually mounted
near the BTS,yet its specific position is determined according to the actual situation.
The structure of grounding copper bar is shown in Figure 3-8.

3.4 Installing Antenna Support
& Note:
In non-turnkey project, the user should prepare the antenna support when preparing the environment.
Huawei is responsible for antenna support installation only in turnkey project.
There are a number of structures and types of antenna support. The following gives two
installation methods for antenna support as examples, namely, installing antenna
support on tower platform and on building-top.
3.4.1 Installing Support on Tower Platform
I. Antenna support structure
Figure 3-12 shows the antenna support installed on tower.

Figure3-12 Structure of antenna support installed on tower
II. Installation requirements
1) Installation plane of the antenna support should be vertical to the horizontal plane.
2) Tower lightning arrester mast should be installed separately with the height
satisfying lightning protection requirements of all antennae. When the support
extends out of the tower platform, it should be ensured that the antenna is within
the protection range formed by 30° pitch angle of the lightning arrester apex, as
shown in Figure 3-13.

3) Make sure that the installation direction of the antenna support would not influence
the receiving (RX)/transmitting (TX) performance and direction adjusting of the
antenna.
4) If necessary, take suspension measures to avoid distortion of the antenna support
as it will be in use for a long time.
5) Whirling arm should be reinforced by reinforcing arm. The length of expansion arm
and whirling arm may be determined according to the onsite situation. The fracture
should be soldered with cover plate to avoid leaking water.
6) All the soldered parts should be secure enough without dry joint and open solder
point. The surface of the support should be covered by anti-rust silvery paint.
Better choose zinc-coated steel for the support.
III. Installation procedure
1) Install a fast pulley on the tower top. Use one or two lifting ropes to hoist the
support to the tower platform via the fixed pulley. Besides, a rope is needed to
control the upward direction of the support;
2) Determine the installation position of the antenna support on building-top
according to the antenna and feeder installation diagram in the engineering design
drawing.
3) Fix the support on the tower with a U-shape fixing clip, as shown in Figure 3-14.
4) Connect the tower platform guardrail and joint soleplate with M12%45 bolt.

II. Installing requirements
1) The installation position of joint for reinforcing arm should not affect the adjustment
of antenna direction and pitch angle.
2) Antenna support must be vertical to the horizontal plane.

Installation Manual

3) Antenna support on building-top must be equipped with lightning arrester, and the
support should be connected to the building lightning-protection network.
4) The surface of the support and all the soldered parts should be covered by
anti-rust paint. All the soldered parts should be secure enough without dry joint
and open solder point.
III. Installing the supporton building-top without parapet
1) Hoist the support to the building-top.
2) Determine the installation position of the antenna support on building-top
according to the antenna and feeder installation diagram in the engineering design
drawing.
3) Solder the lightning arrester on the mainstay support of the antenna (with the axes
aligned).
4) As shown in Figure 3-16, fix the base of the antenna on the building-top vertically
with eight M10%45 expansion bolts.

5) Mainstay support needs to be reinforced with reinforcing arm whose length is
determined according to that of the mainstay support. As shown in Figure 3-17,
the reinforcing arm is connected to the mainstay support through its joint. Connect
the anchors to the reinforcing arm and fix the anchors of each reinforcing arm on

the building-top floor with two M10%45 expansion bolts. Make sure the connection
of the reinforcing arms will not be twisted.
6) As shown in Figure 3-17, connect mainstay support 2 with mainstay support 1
tightly with six M10%80 bolts.

7) There are such cases that the building-top antenna support is not soldered with
outdoor cabling rack; or soldered but the cabling rack is not connected with the
lightning-protection network of the building. In this case, connect the base of the
antenna support to the lightning-protection network of the building with a
lightning-protection connecting bar (the lightning-protection connecting bar is the
installation parts for outdoor cabling rack).
8) Cover all the soldered parts and the support base with anti-rust paint.
9) Base of the building-top antenna support, anchors of the reinforcing arm and the
expansion bolts connected with the floor should all be covered with concrete for
protection.

IV. Installing the supporton building-top with parapet
If there is parapet around the building-top, and it is inconvenient to install the support on
the building-top, just mount the support on the parapet. Figure 3-18 illustrates the
antenna support fixing clip mounted on the parapet.

3.5.2 Hoisting Antenna
Tie a knot at both ends of the antenna with a rope. Persons both on the tower and down
the tower cooperate to hoist the antenna to its position. The persons down the tower
should strain on the rope so as to avoid damage to the antenna due to clashing
between the antenna and the tower body or the building.

Figure3-22 Installing the omni antenna on tower platform
I. Installation requirements
lWhen installing the omni antenna on the tower, make sure the antenna is in the
protection range oflightning arrester on the tower. The distance between the omni
antenna and the tower body should be left at least 1.5m.
lThe antenna axis should be vertical to the horizontal plane with error less than !1°.
lThe TX and RX antenna of omni antenna can be installed on one antenna support,
or be separately installed. The specified installation position should be determined
according to the engineering design drawing.
II. Installation procedure
1) Make the feeding point of the antenna facing down and the jacket near the
mainstay support. The top of the jacket should be on the same level or a little bit
higher than the top of the support.
2) As shown in Figure 3-23, secure the antenna fixing clip and the mainstay support
properly to ensure its load bearing and wind resistibility. It should not be too tight to
damage the jacket of the antenna.
3) Check whether the antenna axis is vertical to the horizontal plane with angle tester.
If the error is equal to or greater than !1°, adjust the antenna axis and then fasten
it.
4) Make waterproof elbow at the antenna connector.

5) Route the antenna jumper with natural jumper curves of proper angle. Generally, it
is required that the radius of the curves be 20 times larger than the jumper
diameter and the jumper be bound to the steel rack of the tower along the support
crosspiece with black cable tie.
