Antenna Installation Technical Parameters
Height
It depends upon network planning.
Azimuth
It depends upon network planning.
Tilt
It depends upon network planning and ranges from 0° ~ 10°.
Antenna direction
It depends upon antenna azimuth. Two antennas in same sector should
point to same direction.
Spacing between diversity antennas
Two antennas in same sector act as diversity receiving antennas for
each other, and have same vertical height. Maximum horizontal
distance (d) between antennas satisfies engineering requirements.
Following formula determines value of horizontal distance (d):
d ≥ 10λ–20λ (or H/d = 11).
Unit of measurement: m
Where:
d is horizontal distance between diversity antennas.
H is vertical height from antenna to ground.
λ is carrier wavelength.
For example, diversity distance of 1900 MHz carrier must be more than
59.055 inch (1.5 m) while that of 800 MHz carrier must be more than
137.79 inch (3.5 m).

1. Install lightning arrester between 7/8" main feeder cable and 1/2"
cabinet-top jumper after main feeder cable enters equipment room.
Lightening arrester has two DIN connectors, one is positive and other
is negative. Keep maximum installation torque for lightning arrester
with DIN connectors up to 25 N m, and with N connectors up to 1.7 N
m. Use adjustable torque spanner to adjust torque to specified value.
2. Lightning arrester has four RF ports, which connects to 7/8" main
feeder cable and 1/2" cabinet-top jumper. RF ports can be connected
either to antenna or to BTS, which provides protection against lightning.

feeder cable where grounding kit is installed, and strip 7/8" feeder
cable sheath at installation position.
2. Put grounding kit grip ring around feeder cable external conductor, and
then buckle the ring. Figure 62 shows this process.
FIGURE 62 - BUCKLING GRIP RING
3. Use waterproof self-adhesive tape to wrap entire connecting place.
Overlap each layer as half of the previous layer each time. Figure 63
shows this process. Keep wrapping direction same as buckling direction
of grip ring to make connection secure. Press adhesive tape along
grounding kit edge to make tape fit in closely with grip ring of

Cabinet Jumper Installation
Connect cabinet and main feeder cable by a 1/2" super-flexible feeder
cable. Jumper connector depends on cabinet and main feeder cable.
Usually both connectors are positive DIN connectors.
Connect antenna feeder jumper to one of fixed antenna feeder bases
(HYCOM1 ~ HYCOM6) on cabinet bottom.
Testing Antenna Feeder System
Test antenna feeder to check whether antenna matches feeder cable and
works properly. This test involves receiver and transmitter indexes. Main
tests are voltage standing wave ratio (VSWR) and RF transmit power test.
Ensure that following conditions are satisfied before antenna feeder
system test:
Antennas and feeder cables are installed and interfaces connected to
antennas are disconnected.
Feeder cable and connectors are in good condition and not damaged,
and connectors are connected properly, and antennas point to right
directions.
Connectors are not sealed with adhesive tapes.
Warning:
Avoid high-intensity microwave radiations during high-intensity RF signal
device operation.
Do not screw off connectors of transmitter output feeder or antenna feeder
cable during operation.
VSWR Test
VSWR test refers to voltage standing wave ratio (VSWR) test of TX
antenna. BTS tester SITE MASTER 332B is recommended for test. VSWR
must be smaller than 1.5 otherwise check antenna feeder system again.
BTS system generates primary and secondary alarms for VWSR more than
1.5.
RF Transmit Power Test
RF transmit power refers to average RF carrier power. Carry out RF
transmit power test to determine power at input end of combiner and
verify average transmit RF carrier power. Use site test instrument for test.
BTS tester MASTER 332B is recommended. Conduct test at input end of
combiner (output end of power amplification module).

Waterproofing Connectors
Seal the connectors of each cable after ensuring that antenna feeder
system test is complete and result is OK. Use two types of adhesive tapes
for sealing: waterproof self-adhesive insulated tape and electrically
insulated adhesive tape. First wrap connectors with electrically insulated
adhesive tapes and then with waterproof adhesive tapes, and finally with
electrically insulated tapes again.
Electrically insulated adhesive tapes must be fire and cold-resistant and
corrosion-proof, and must be able to work under a voltage of 600 V.

Cabinet Packing Procedure
Follow procedure below to pack a cabinet:
1. Blow away dirt from cabinet and clean it with ethyl alcohol.
2. Put dustproof caps onto DB9 socket and N-type socket at the set top,
SAA socket and DB25 socket at E1 cable set top, and 17W2 female
sockets at the DPA layer.
3.
Lay cabinet onto the ground covered with a foam cushion, with
cabinet door upward. Lower hook of an electric crane to a proper
location. Put nylon rope on the hook around 4 hanging points. Hoist
the hook to lift cabinet.
4. Open aluminum foil compound film bag and put cabinet into the bag.
5. Put a cushion into a wooden packing box, push wooden packing box
until it is under the hoisted cabinet and put the cabinet slowly into the
wooden box.
6. Put desiccant bags into aluminum foil compound film bag. To wrap
cabinet tightly by aluminum foil compound film bag, extract air in the
bag with a cleaner. Seal the aluminum foil compound film bag.

Board Packing
Before packing CBTS O1 cabinet, ensure to dismount heavy boards such
as RFE-RFE, RFE-DIV, DPA and TRX from the cabinet, which are packed
separately.
Board packing procedure
RFE, TRX and DPA Packing
Figure 90 shows that these boards are packed inside a packing foam
box first and then put in the packing boxes.
FIGURE 90 - INNER P ACKING FOAM BOX
Board packing procedure is as follows:
i.
Clean the board panels with alcohol.
ii. Place RFE, TRX and DPA boards into their own inner packing foam
boxes. Mark cover and bottom of foam box with silkscreen for
packing.
iii. After TRX and DPA boards are put into a foam box, put them into a
universal paper packing box made for boards. Figure 91 shows
packing box.

paper packing box for bases. After packing, put the paper packing box for
bases into a general wooden packing box for parts.
Engineering Materials Packing
Put engineering materials (such as antenna, power and transmission
cables, 1/2" jumper, GPS cable, three-way feeder clamp, and grounding
clip) into original paper packing boxes.
Put small engineering materials (such as the lightning arrester, adhesive
tape and connecting nose) into a general external paper packing box for
engineering accessories according to their quantity codes.
Seal above paper packing boxes and put them into a wooden packing box
for engineering accessories.

Transportation
Take following measure for equipment transportation:
Products are in a specified container and according to container
transportation marks.
There are no more than 3 layers for wooden packing box and 4 layers
for paper packing box. Sophisticated equipment is placed above and
others below. Centre of gravity height is no more than 78.74 inch (20
m), and vehicle is not overloaded.
Vehicle velocity is such to ensure safety based on road conditions.
Products are away from flammable, explosive or corrosive articles.
Protect equipment from rain, snow or other liquids, dirt, sunlight,
collision and materials with strong magnetism and radiation while
transportation.
Cover equipment with tarpaulin during open-air transportation.
In long-distance transportation, do not load equipment on an open ship
or carriage. In case of transhipment, do not store equipment in an
open storehouse.
Deliver and store precision instrument, meters, computers and
monitors according to moisture, shock and pressure-proof labels in the
packing box.
Always keep products upright.
Pay attention to safety while handling equipment. Ensure that only
skilled workers are operating the handling tools.
Storage
Take following measure for equipment storage:
120
Products and its components are in original packages.
Storage sites are clean, dry, and ventilated, with air-conditioning and
lighting facilities. Temperature and humidity range is according to the
requirement.
Equipment is not under direct sunlight.
Storehouse is equipped with moisture-proof, dustproof, shockproof and
corrosion-resistance facilities, and the corresponding antistatic facilities
for static-sensitive materials.
All goods are clean and in order with clear labels.
Keep a record of all equipment. Ensure goods location codes or other
necessary marks for the stored materials.
