1 Assemble the Antenna Installers: A\B\C\D (10 minutes)

a Assemble the support

b Fix the support onto the antenna

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 upper support Assemble the lower support

5

Wrap three layers of waterproof tape

Wrap three layers of insulation tape

Fix cable ties

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.

2 Connect Jumpers to the AntennaInstallers: 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.

b Stick color rings

c Seal the connectors

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.

Optional

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.

7

4 Install the Antenna Installers: A\B (50 minutes)

a Install the antenna on a pole

b Make the waterproof curve of jumpers

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

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.

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

8

4 Install the Antenna Installers: A\B (50 minutes)

d Adjust the downtilt angle of the antenna

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.

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

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

Method 1: Using the scale on the upper support

Method 2: Using the inclinometer

Method 3: Adjust the electrical downtilt angle (only for the MET antenna)

5 Make Feeder Connectors Installers: C\D (50 minutes)

a Cut feeders

b Make feeder connectors / Stick color rings

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.

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

Cut feeders according to the length identifiers on the feeders.

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

10

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.

11

8 Fix Feeder Fasteners Installers: C\D (30 minutes)

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

7 Connect Feeders to Jumpers of the AntennaInstallers: 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

Fix the cable ties

Finished

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.

12

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

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

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.

13

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

a Strip the feeders

b Install grounding clips of the feeders

2. Fix DIN female connectors to the feeders. Stick the same color rings as the original ones at the position 200 mm away from the feeder connectors.

1. After length of the jumpers to be distributed is determined, cut six jumpers and fix DIN male connectors to both ends of the jumpers.

2. Stick color rings corresponding to the sectors at one end of the jumper (connected to the feeder) at the position 200 mm away from the jumper connector.

d Bind the indoor jumpersc Connect feeders and jumpers

Connect the feeders to the jumpers with the same color rings.

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

12 Check the Antenna System Installers: A\B\C\D (15 minutes)

Ensure that the connectors of feeders and jumpers are installed securely and correctly.

Ensure that feeders and jumpers are in good conditions.

Each feeder is connected to the jumper with the same color rings.

Proper grounding measures are taken at three positions on the outdoor feeders.

The antenna should be installed at the position as specified by the design and securely fixed to the pole.

Antenna

No unnecessary adhesive tape or cable tie is left on the feeders and jumpers.

Waterproof curves are made for jumpers at the antenna side and outdoor feeders near the feeder window.

Ensure that all outdoor connectors are sealed for waterproof purpose and that the sequence of wrapping taps is correct.

Color rings are sticked to the correct positions.

Feeders are distributed neatly without any cross. No bare conductor inside the feeders is exposed.

Feeder and jumper

The antenna should be in the protection range of the lightning rod (within the tilt angle of 45o under the lightning rod).

In the forward direction of the antenna, the antenna is not obstructed by the tower body.

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.

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.
