1.2 Personnel Requirements
The antenna & feeder system is installed by the antenna & feeder installation
personnel under the supervision of the project supervisor.
1.2.1 Requirements for project supervisor
The project supervisor should:
zBe familiar with the materials, tools and methods related to the antenna & feeder
installation;
zBe familiar with the installation flow and the installation methods of all the parts;
zHave a strong safety consciousness.
1.2.2 Requirements for tower installer
The tower installer should:

BTS3802C & RRU Chapter 1 Installation Preparations
1-2
zObtain the relevant certificates after relevant training;
zBe in good health, free of alcohol and have paid for personal safety insurance;
zUse the safeties following their usage instructions;
zNever wear loose clothes or slippery shoes when performing installation.
1.3 Preparation Tasks for Different Installation Roles
zThe project supervisor should contact customers who will be present on the site
before kickoff so as to prepare the instruments and tools needed. If the feeders
are to be routed through the cabling holes between buildings, it is necessary to
remind the customers of the keys to the rooms or roof corridor through which the
feeders run;
zAll persons on the site must wear safety helmets, and each installation team
should be provided with a first-aid kit;
zThe personnel under the tower are under the obligation to keep unrelated
persons, especially children away from the engineering site, and to take care
installation parts and instruments and prevent loss or damage from occurring;
zThe personnel on the tower must fasten safety belts, and get the tool kit and
some simple bandages such as the Woundplast handy.
Caution:
zWhen multiple persons are to climb the tower, the person carrying the tool kit should climb up last
and down first lest a barely fallen tool should injure others.
zThe tool kit should be opened only when tools are needed and be closed immediately after getting
the tools.

1.5 Testing Antenna & Feeder Equipment
To guarantee the quality of the installation of the antenna & feeder system, it is
suggested that the antenna & feeder equipment be tested before the installation. To
reduce the operations on the tower, please test the equipment, assemble the antenna
and add the feeder connectors on the ground. In the case of roof installation, if there
is enough space, the preparation can be done on the roof, or else should be done on
the ground or in the room.
1.5.1 Testing antenna
Since antenna is vulnerable during transportation, it is necessary to inspect the
antenna carefully prior to the installation for any visible damage, crack or connector
problem. If any, contact the personnel concerned immediately and suspend the
installation.
If no obvious problem found, connect the antenna with the corresponding jumper and
test its Voltage Standing Wave Ratio (VSWR) using the radio analyzer. Try different
orientations when testing the antenna, as it is related to the antenna VSWR. If the

Installation Manual -Antenna & Feeder System Installation
BTS3802C & RRU Chapter 1 Installation Preparations
1-4
antenna VSWR is higher than 1.5 in the case of all orientations, there may be some
problems with the antenna or its connectors, and in this case, please perform the
above test again. If the antenna VSWR is lower than 1.5 just in the case of some
orientations, it is not definite that the antenna has problems and the installation can
proceed. Upon completion of the antenna installation, re-test the antenna VSWR. If
the antenna VSWR is still too high, it can be concluded that the problem lies in the
antenna and therefore, the antenna should be replaced.
1.5.2 Testing TTA
Inspect the TTA for any obvious damage, and then test the VSWR on both ports.
During the test, make sure that the port not being tested is connected with the 50 Ω
matched terminal load. If not, error of the test result may be great.
This test is implemented when the equipment is not powered on. If the test result is
much different from the corresponding index, the TTA should be replaced.
Note:
Normally, the TTA should be tested when it is powered on, for the result is better than that in power-off
case. The test mentioned above simplified is a simplified operation applicable to occasions without
corresponding test. If conditions permit, installer should also test the current of the powered-on TTA. If
the TTA current is within the range of 50~175mA, the VSWR is considered to be suitable.
1.6 Adding Feeder Connector
Feeder connectors should be added to the feeders on the installation site. It is
recommended that the connectors of the feeders to be used on the tower be made on
the ground, and then be wrapped up using soft materials such as sponge for
protection purpose before being hoisted, as shown in Figure 1-1. There are two types
of connectors: 7/16 DIN and N. The adding methods for the two types are the same.
The detailed operation instruction for adding the feeder connector can be found in the
packing box. Do follow the instruction. After adding the connectors, the instructions
should be kept for later reference.
