Installation Manual Antenna and Feeder System InstallationWCDMA NodeB

Chapter 5Installing GPS Antenna and Feeder System

5-2

Install the antenna away from the radiation from the front of the main lobe of the

mobile communication antenna.

Do not install the antenna under the microwave signal from microwave antenna,

the high voltage cable or under the intense radiation of television tower.For lightning protection purpose, install the antenna in the center of the rooftop.

Be sure not to install the antenna at the corner of the rooftop, because the corner

is most possibly subject to the lightning strike. Install the antenna in the place with special lightning rods or similar facilities

around such as telecommunication towers.

Locate the antenna within the effective protection range of the lightning rod. That

is, the included angle between the vertical direction and the straight line between

the GPS antenna and the top of lightning rod is less than 30. If there is no tower

or lightning rod around, it is necessary to install such a facility meeting the

lightning protection requirement.The horizontal distance from the lightning rod to the antenna is within 2~3m.

The height of the lightning rod is more than 0.5m higher than that of GPS

antenna receiving end.

5.3 Installing Antenna Support

5.3.1 Installation Methods and Requirements

There are three installation methods for GPS antenna supports:

Installing GPS antenna supports on a cement base

Installing GPS antenna supports on a parapet on the rooftop

Installing GPS antenna supports on a tower.

The requirements for the three installation methods are as follows:

I. Requirements for the Installation on a Cement Base

The dimension (length width height) of the cement base is 500 mm 500

mm 200 mm.The cement base is made of concrete and reinforcing steel bars. It is strong

enough for mounting expansion bolts.

The upper surface of the cement base is as level as possible so that the antenna

support pole can stand upright.

If the customer permits and the roof has reliable waterproof capability, roughen

the installation position on the rooftop to fortify the joint between the cement

base and the rooftop.

Take the ambient temperature into consideration when making the base.

Especially in cold areas, prepare the cement base beforehand lest that the

5-3

project is prolonged due to the cold weather in which the construction is not

allowed.

II. Requirements for the Installation on a Parapet

The location and surroundings of the parapet should meet the requirements

specified in 5.2 Positioning GPS Antenna

Do not affect the appearance of the building when installing the antenna support

on the parapet. Therefore, build the parapet in an unnoticeable place.

The parapet is strong and high enough for drilling to mount the expansion bolts.

III. Requirements for the Installation on a Tower

Install the GPS antenna at the bottom of the tower to keep it as far as possible

from the high-power antenna on the tower top.

Fix the antenna using the antenna support to avoid the interference from thetower body.

There is no obstacle around affecting the quality of signal receiving.

4) Insert the antenna support pole into the base, and then check that it stands

upright. The included angle between the stand pole and the upright direction is

smaller than 5.

II. Installing the Antenna Support on a Parapet

The procedure of installing the antenna support on a parapet is as follows.

1) Remove the base of the support if there is any.

2) Stand the pole of the antenna support with the receiving end pointing upward.

Hold the pole upright against the parapet.

3) Mark the positions of the holes on the parapet.

4) Use at least two anchor ears to fix the pole to ensure stability and reliability. The

distance between the two anchor ears is less than 400 mm. The positions of the

upper and lower anchor ears are symmetrical on the parapet.

Note:

Add rubber washers when using the anchor ears to fix the antenna pole to improve reliability.

5) Use the 12 drill bit to drill holes on the marks.

After installation, try shaking and turning the pole to confirm the reliability of the

installation. Check that the included angle between the pole and the upright directionis less than 5 to ensure that the antenna supports upright.

5.4 Installing GPS Antenna

5.4.1 Antenna Appearance

The NodeB adopts UTONCORE GPS antenna. See Figure 5-5.

5.4.2 Installation Procedure

The procedure of installing the UNONCORE GPS antenna is as follows:

1) Remove the bolt at the bottom of the antenna and apply the rubber washer (anaccessory of the antenna) to the bottom.

2) Insert the antenna into the position "M3" in Figure 5-4.

3) Add the metal flat washer (an accessory of the antenna) to the jumper connector

at the bottom of the antenna with the washer head against the bottom of "M3".

4) Connect the antenna and jumper and tighten up the connector.

5) Tighten the four bolts to fix the GPS antenna on the antenna support.

6) Waterproof the connecting points of the antenna. For details, refer to 4.14

Waterproofing Outdoor Connectors.

7) Paint the antenna support with rustproof paint, especially the bolts, expansion

bolts and the places around the bolt holes.

5.4.3 Binding Jumpers

Bind the jumpers to the antenna support pole using cable ties. Observe the following

rules when binding jumpers:

Fasten the cable ties in the same direction of the cable with their spacing as 200

mm.

When cutting the extra end of a cable tie, leave a slack of 3~5 mm lest the cable

ties fall off due to temperature change.The cutting sections are flat.

5.5 Installing Feeders

5.5.1 Laying out Feeders

Before feeder layout, check the environment including the tower and the rooftop, and

determine the layout plan and layout procedure as per the engineer drawing.

Caution:

When the distance from the antenna to the NodeB is greater than 100 m, use the 7/8 feeder to reduce

the signal loss. Otherwise, use the 1/2 feeders.

Observe the following requirements when laying out the feeders:


115/132



5-8

The feeder route from the tower to the equipment room where the cabinet is

located is clear and easy for fixing the feeders.

Route the feeder according to the cabling requirements of the equipment room,

with reliable rainproof and anticorrosive measures.Make a downward waterproof curve for the feeder before leading it into the

equipment room. The vertical distance between the lowest point of the curve and

the feeder entrance is at least 200mm to prevent rain water.

During feeder layout, protect the unused feeder connectors with reliable material,

for example, board package.

To install the antenna on a building rooftop, fix the feeder with plastic clips

attached with steel nails along the foot of the wall on the rooftop. The spacing of

the clips is 1m. Alternate regularly the directions of the clip head. If two feeders

meet, bind them without intertwining and curves.

When routing the feeder, make sure to uncoil the cable coil first to preventbending the feeder. If you have to bend the feeder, the curve radius must be no

less than the minimum radius allowed.

5.5.2 Grounding Feeders

Ground the GPS feeders when routing them. The following describes feeder

grounding in different installation modes.

I. GPS Antenna Installed on a Tower

Observe the following requirements to ground the GPS feeders when the GPS

antenna is installed on a tower:

Install a grounding clip within 1m around the antenna lightning arrester, and

connect the grounding cable to the tower.

Ground the feeder at the bottom of the tower 0.5~1m above the turn where the

feeder is routed from the cabling rack to the tower.

Install a grounding clip outside the feeder window (as close as possible).

Connect its grounding cable to the outdoor grounding bar of the equipment room.

If the feeder on the tower is longer than 60m, install lightning protection clips inthe middle part of the tower, with the clip spacing as 20 m.

II. GPS Antenna Installed on a Rooftop

Observe the following requirements to ground the GPS feeders when the GPS

antenna is installed on a rooftop:

To install the GPS antenna on the rooftop independently, install a grounding clip

before the feeder entrance to the feeder window (at the nearest point). Connect

the grounding cable to the outdoor PGND bar of the equipment room.


116/132



5-9

If the feeder is longer than 60 m, install lightning protection clips in the middle

part of the feeder, with the clip spacing as 20 m.

5.5.3 Leading Feeders into Equipment Room

Note:

This step is needed only for indoor NodeB. For outdoor NodeB, skip this section for BTS3806A.

Lead the feeders into equipment room through feeder window. For details, refer to

4.12.2 Procedure to Lead Feeders into Equipment Room.

5.6 Installing Lightning Arrester

The lightning arrester protects the GPS satellite card in the cabinet.

Currently there are two types of lightning arresters: iS-MR50LNZ+6 and

DGXZ+6NFNM-A. The installation procedures for each type are described below.

Caution:

When the distance from the antenna to the NodeB is longer than 100 m, use the 7/8 feeders to reduce

the signal loss. In this case, connect one end of the lightning arrester to the GPS port on the cabinet top,

and the other end to the 7/8 feeder through a jumper.

5.6.1 Installing iS-MR50LNZ+6 Lightning Arrester

Pay attention to the following when installing the iS-MR50LNZ+6 lightning arrester:

The "PROTECTED" end of the lightning arrester is connected to the port GPS_0

or GPS_1 on the cabinet top.

Do not ground the lightning arrester for GPS satellite card.

5.6.2 Installing DGXZ+6NFNM-A Lightning Arrester

Figure 5-7 illustrates an appearance of DGXZ+6NFNM-A lightning arrester.

Figure 5-7DGXZ+6NFNM-A lightning arrester

Pay attention to the following when installing a DGXZ+6NFNM-A lightning arrester:

The two connectors of DGXZ+6NFNM-A lightning arrester are respectively male

and female. Connected the male connector of the lightning arrester to the port

GPS_0 or GPS_1 on the cabinet top.

Do not ground the lightning arrester.

5.7 Testing Feeders

After the installation of the antennas and feeders, do not connect them with the

equipment immediately. Check the resistance with a multimeter between the feeder

screen layer and the core. The resistance is several megohms at least. If there is

short circuit, check whether the feeder is damaged.

During the installation, any operation error may lead to short circuit or core breaking.

Use the following methods to check whether the core is broken.

Remove the antenna, and then short-circuit screen layer and the core at one end of

the antenna. Check the resistance at the other end between the screen layer and the

core. If the resistance is infinite, the feeder core is broken.


118/132



5-11

If the feeder is confirmed damaged, find out the damage point with the engineering

personnel. If the length of the undamaged part is sufficient, add a connector (it can be

the one on the original feeder) to it for reuse.

5.8 Waterproofing Outdoor Connectors and Feeder Window

Waterproof the outdoor connectors and feeder window when the GPS antenna and

feeder system passed the test. For details, refer to 4.14 Waterproofing Outdoor

Connectors and 4.15 Waterproofing Feeder Window.

The point 200 mm away from the lower connector under the outdoor antenna.

The point 200~300 mm down the tower platform.

The point 200 mm away from the outside of the feeder encapsulation window.

The bents.

When binding labels to the feeders, make sure that they are neatly laid out. All labels

face the same direction, and so do the cable ties. When cutting off the extra part of a

cable tie, make sure to leave a slack of 5~10 mm.

III. Binding Labels for Indoor Feeders

Attach a feeder for an indoor feeder to the feeder at the point 200 mm away from the

connector.

When attaching the labels, make sure that their contents face the proper direction so

that they can be easily identified.

B.4 Labels for Jumpers

I. Label Contents

The contents of the labels for jumpers are the same as those for outdoor feeders.

Refer to "B.3.1 I. Label Contents".

III. Binding Labels for Jumpers

Attach labels for the indoor jumpers to the jumpers at the points 100 mm away from

both ends. Attach labels for outdoor jumpers to the jumpers at the point 100 mm away

from one end. Because the jumpers are short, attach one label for one jumper only.

When attaching the labels, make sure that their contents face the proper direction so

that they can be easily identified.
