1 Assemble the Antenna

a

Installers: A\B\C\D (10 minutes)

1.

The antenna described in this guide is an 800 M FET antenna of Huawei. For installation of other antennas, see the relative manuals.

2.

The assembly of three antennas is complete on the ground.

Assemble the support

Assemble the upper support

b

Assemble the lower support

Fix the support onto the antenna

4

2 Connect Jumpers to the Antenna Installers: A\B\C\D (15 minutes)

a

Connect jumpers

1.

Use six jumpers with fixed length.

2.

(Optional) If no jumper with a fixed length is available, cut a jumper into proper lengths and fix DIN male connectors to both ends of the jumpers.

Optional

b

Stick color rings Ensure that the color rings are in the correct direction and positions. Wrap the jumpers with 2 or 3 layers of tape to make the color rings. The distance between neighboring color rings is 10 mm to 15 mm.

c

Seal the connectors

Wrap three layers of waterproof tape

Wrap three layers of insulation tape

Fix cable ties

Finished

1.

When wrapping the tape, ensure that the upper layer covers more than 50% of the lower layer. Wrap each layer around the jumpers tightly. Before wrapping the waterproof tape, stretch the tape till the width of the tape becomes 1/2 of the original.

2.

Wrap the metal connector using waterproof tape with extended lengths about 20 mm, and wrap the waterproof tape using insulation tape with extended lengths about 10 mm.

5

3 Lift the Antenna

Installers: A\B\C\D (30 minutes)

1.

Installers A and B climb onto the tower. Installer B fixes the fixed pulley onto the support of the tower platform and puts the lifting rope through the fixed pulley.

2.

Installer D uses plastic bags or tape to wrap the jumper connectors and then coils the jumpers. Fasten the lifting rope to the upper support of the antenna and the traction rope to the lower support.

3.

Installer C pulls down the lifting rope, and installer D pulls the traction rope outwards to prevent the antenna from hitting the tower.

4.

Installers A and B hold the antenna and unfasten the ropes.

5.

After three antennas are lifted onto the platform, do not remove the fixed pulley, because the feeder needs to be lifted later.

6

4 Install the Antenna a

Installers: A\B (50 minutes)

Install the antenna on a pole

Do not overtighten the screws of the upper and lower supports. But the screws can not be too loose, or the antenna may slide.

b

Make the waterproof curve of jumpers

Bind the jumpers at several positions on the pole and tower platform.

c

Adjust the azimuth of the antenna The operation must be performed by two personnel. The personnel under the tower use the compass at the position where is 10 m to 20 m away from the tower. The personnel on the tower adjust the antenna. After the azimuth reaches the requirement, tighten screws of the upper and lower supports.

7

4 Install the Antenna d

Installers: A\B (50 minutes)

Adjust the downtilt angle of the antenna Method 1: Using the scale on the upper support

Push the antenna forward and backward till the scale is adjusted properly. After the downtilt angle reaches the requirement, tighten screws of the scale. Method 2: Using the inclinometer

Before adjusting the downtilt angle, adjust the angle of the inclinometer to the desired angle. Push or pull the antenna till the bead in the inclinometer is located in the middle horizontally. After the downtilt angle reaches the requirement, tighten screws of the scale. Method 3: Adjust the electrical downtilt angle (only for the MET antenna)

Turn the adjustment tool until it aligns with the scale on the ruler.

8

5 Make Feeder Connectors

Installers: C\D (50 minutes)

Measure and cut six feeders (40 m), unwind the feeders, make feeder connectors, and stick color rings to the feeders on the ground.

a

Cut feeders

Cut feeders according to the length identifiers on the feeders.

b

Rotate the feeder cutter till the inner and outer conductors are completely cut.

Make feeder connectors / Stick color rings

9

1.

Fix a DIN female connector to one end of the feeder.

2.

Stick color rings at one end of the feeder. Ensure that the first color ring is at the position 200 mm away from the feeder connector.

3.

Stick color rings at the other end of the feeder. Ensure that the first color ring is at the position 200 mm away from the feeder end.

6 Lift the Feeder

Installers: A\B\C\D (30 minutes)

1.

Installer D wraps the feeder connectors with plastic bags and tape, fasten the lifting rope to the feeders at the position 0.4 m away from the feeder connectors and fasten the traction rope at the position 4.4 m away from the feeder connectors.

2.

Installer C pulls down the lifting rope, and installer D pulls the traction rope outwards to prevent the feeders from hitting the tower.

3.

Installers A and B hold the feeders, unfasten the ropes, and fasten the feeders onto the tower platform to prevent them from falling down to the ground.

4.

After six feeders are lifted onto the tower one by one, installer B removes the fixed pulley.

10

7 Connect Feeders to Jumpers of the Antenna Installers: A\B (30 minutes) On the tower platform, connect the feeders and jumpers with the same color rings. Seal the connectors.

Wrap three layers of waterproof tape

Wrap three layers of insulation tape

8 Fix Feeder Fasteners

Fix the cable ties

Finished

Installers: C\D (30 minutes)

1.

The installation spacing of the clips for the feeder (7/8 inch) is 1.5 m to 2 m. The installation spacing of the clips for the feeder (larger than 7/8 inch) can be extended.

2.

If multiple rows of feeder fasteners need to be fixed, arrange the fasteners properly to keep a neat appearance.

Do not tighten the bolts, so that feeders can go through the bolts.

11

9 Install and Ground Outdoor Feeders Installers: A\B\C\D (160 minutes)

Feeders should be fixed from top to bottom. Sort out the feeders and fix them through feeder fasteners. Install feeder grounding clips at the grounding point of the feeders and then fix the feeders.

Stick color rings to the feeders within 1 m from the position where the feeders leave the tower.

12

9 Install and Ground Outdoor Feeders Installers: A\B\C\D (160 minutes)

a

Strip the feeders The stripped part of the feeder should have the same length as the metal jacket of the grounding clip.

d Bind the indoor jumpers

Route the jumpers along the indoor cable rack and bind the jumpers with cable ties.

15

12 Check the Antenna System

Installers: A\B\C\D (15 minutes)

After the installation is complete, check the antenna system according to the following table. Then, correct the items that do not meet the requirements.

Item VSWR of the antenna system

Requirement Use a VSWR tester to measure the VSWR at the indoor jumper. The VSWR should be less than 1.5 or the value required by the project. The antenna should be installed at the position as specified by the design and securely fixed to the pole.

Antenna

The error of the antenna azimuth should not be bigger than 5o, and the error of the tilt angle should not be bigger than 0.5o. In the forward direction of the antenna, the antenna is not obstructed by the tower body. The antenna should be in the protection range of the lightning rod (within the tilt angle of 45o under the lightning rod). Feeders are distributed neatly without any cross. No bare conductor inside the feeders is exposed. Ensure that feeders and jumpers are in good conditions. Each feeder is connected to the jumper with the same color rings. Color rings are sticked to the correct positions.

Feeder and jumper

Proper grounding measures are taken at three positions on the outdoor feeders. Ensure that the connectors of feeders and jumpers are installed securely and correctly. Ensure that all outdoor connectors are sealed for waterproof purpose and that the sequence of wrapping taps is correct. Waterproof curves are made for jumpers at the antenna side and outdoor feeders near the feeder window. No unnecessary adhesive tape or cable tie is left on the feeders and jumpers.

16

Appendix 1 Stick Color Rings

a

1.

By sticking color rings of different colors and different quantities to the feeders and jumpers, you can distinguish sectors and RF paths.

2.
