6.3.1 MAST/POLE INSTALLATION
6.3.1.1 MAST/POLE SELECTION
The types of section of the mast/pole where the MBS Unit can be mounted are the followings:
Circular section: Diameter from 30 mm to 130 mm
Square section: From 30 mm x 30 mm to 85 mm x 85 mm.
L section: From 30 mm x 30 mm to 110 mm x 110 mm.
In the choice of the mast/pole where the MBS Unit is being installed the following recommendations
must be followed:
The mast/pole has to support the loads due to the installation of some elements on
them.
The mast/pole has to support the loads due to the action of the wind, snow as well as its
own weight, because these are going to induce its flexion.
o The mast/pole must have the enough inertia both lateral and frontal in order that the actions
of different loads do not induce permanent deformations on it.
The manufacturer of the mast/pole must evaluate the structural factor of the mast/pole
correctly depending on its type.
It is necessary to take into account both the height where the MBS Unit is installed and
its weight/dimensions (See section “MBS Unit” in chapter (F067326PT) “SBS Technical
Description” in the Standard Technical Manual).
It is recommended to choose a lattice mast/pole in case of this one has a high height
and it is going to be submitted to important flexion efforts. In any case, it is
responsibility of the manufacturer of the mast/pole to determine if the resistant
section of mast/pole is suitable.
The brackets should be installed tight enough to support the MBS Unit without causing deformation
of the mast/pole or areas of corrosion.

Page 27 of 62
en
Once mounted in its definitive location, if the vandal resistant kit is available, it will prevent the
access / disassembly not authorized.
In case of installing more than one MBS Unit on the same mast/pole, it is recommended not to
mount one above the other one to avoid the heat transfer from the MBS Unit low to the MBS Unit high. If the
MBS Units have to be installed in the same vertical axis these must be oriented in different directions to
increase the separation of them as far as possible, depending on the length of wiring between both
equipments (1.5 m approximately).

6.3.5 REQUIREMENTS TO CONSIDER DURING THE ANTENNA INSTALLATION
The antennas installation always will depend on TX frequencies assigned to each MBS Units that are part of
a MBS.
As a general rule, the frequencies assigned to the MBS Units of each MBS shall comply with the following
restrictions:
Sub-band.
When the MBS Units belong to the same band, these must belong to the same sub-band. Otherwise, the
duplexer TX and RX filters do not provide the necessary insulation. For example, you should not combine a
MBS Unit with 390-395 MHz TX subband with another with 395-400 MHz TX subband.
Frequency spacing:
∆f ≠ DS/n
∆f ≠ DS/n ± 25 KHz
If DS/n is not a multiple of 25 KHz, take the multiple of 25 KHz nearest lower value to DS/n and its 2 adjacent
channels (± 25 KHz).
Where:
∆f is the TX frequency spacing between the MBS Units.
DS is the duplex spacing,
n is an integer number.
If the MBS Units are combined into one antenna, will be mandatory fulfill the restrictions listed above.
If each MBS Unit has its own antenna, there are several possible cases depending on the level of
compliance with the foregoing restrictions:

TETRA MBS UNIT. INSTALLATION GUIDE
F067646PT_2800
Page 41 of 62
en
- Case 1: All MBS Units in the MBS comply with the restrictions about subband and frequency separation. In
this case, is allowed to install all the antennas in the same horizontal plane following the guidelines normally
applied for SBS sites about the horizontal distance between each antenna and the mast.
- Case 2: The restrictions about subband and frequency separation are not complied between the MBS Units
in the same MBS. In this case, the antennas installation should be done keeping an enough vertical
separation between each antenna of MBS in order to obtain the necessary isolation to avoid, when all MBS
Units are transmitting, an increase in the RSSI level respect to the level measured when the MBS Units are
not transmitting.
This option is not advisable, especially if the tower which antennas will be installed is not elevated over the
ground, because may be differences of coverage between the upper antenna and the lowest that could
affect the communications performance.

6.3.6 CONNECTIONS
This section shows the connections to be made and the characteristics of the material to be used.
The MBS Unit is a weather-protected device once the equipment has been installed in its final location; make
sure that there is no MBS Unit connector without plug or cable connected. Besides, the external wiring
connections of the MBS Unit must be protected from weather, (vulcanizable tape can be used if it is
necessary).
To connect two MBS Units you must have the interconnection kit for additional carrier (Cod.
D014001PT). This is obtained as an independent accessory. In the following table is showed the connection
between two MBS Unit using the interconnection kit

In both cases:
The power supply cable to the MBS Unit must be provided by the installer with the proper
power supply connector adapted for the connection to the electrical network or to a 24 VDC
source.
Ensure that the earth connection is made before equipment’s start-up. The MBS Unit has an
earth connector; this connector will connect to the earth protection of the installation, which
is different to the earth protection of the lightning rod.
Make this connection with a cable of, at least, 25 mm2 (AWG 3) section
NEVER use a gas or electricity conduit as an earth.
6.3.6.3 ANTENNA CONNECTION
With every MBS Unit, a RF super-flexible wire, N-Male – N-Male, is supplied to connect the
ANT connector of the MBS Unit with the RF wire of the antenna.
Note: In case of installation a MBS Unit with diversity 2, it is recommended to contact your
supplier and/or installer who will provide the additional RF super-flexible wire (Cod. 208931).
The RF assembly depends on the cable type used in the installation up to the antenna.
The RF cable must have a protection against water entry (vulcanizable tape).
Choose the most adaptable antenna for the installation. The antenna must have an
impedance of 50 ohms to the equipment transmission frequency. Install the antenna in
accordance with the manufacturer’s instructions.
Use a coaxial cable, avoiding as much as possible large cable lengths. Cable impedance is
50 ohms.
In installations with diversity, the greatest gain is achieved by placing the antennas on the
same horizontal plane with a minimum distance of 5.5 m between them.
Measure the ROE of the installation. Never accept a ROE greater than 2

7. START UP/CONFIGURATION/VERIFICATION
IMPORTANT: Ensure that the power supply of the MBS Unit is the proper one
before switch it on; an erroneous power supply can cause damages in the
equipment.
Every MBS Unit has in its labelling the diverse options that it offers. If the MBS Unit
includes the option O148017PT, this it will have to be powered with AC (220/110
VAC), however, if the MBS Unit includes the option O148018PT it will have to be
powerred with +24 VDC nominal voltage.
Preliminary considerations for carrying out the MBS Unit start up:
- To start up the equipment, this must have the final IP correctly configured (see chapter of
infrastructure configuration (F067220PT) in the Technical Manual).
- Refer to the radio link used to configure this device. Make sure this element is properly
connected to ground.
The steps to perform the final settings are:
1.
Before connecting power supply to the MBS Unit, make sure the right voltage level reaches the
power supply cable connector.
2.
Provide power to the MBS Units through the POWER_IN connector.
3.
Wait for the MBS Unit initialization (about 3 minutes).
4.
Verify that you have access to the MBS (by performing a "ping"). Make partial checks in case of no
response from the MBS, perform pings to intermediate elements: SNI Node radio link remote
site radio link MBS.
5.
From NMS, register the MBS Unit(s), completing the necessary settings (see chapter of
infrastructure configuration, F067220PT, and the client's user manual NMS, F067201PT).
6.
Verify the absence of alarms in monitoring module and check with a radio terminal that it is
registered and you can make and receive calls. In case of interference or coverage fault alarms see
chapter of the infrastructure adjustment (F067218PT).

8. INCIDENTS
The MBS Unit must be repaired by authorized technical personnel only. There will not
be performed any repair of the MBS Unit and it will have to be sent to factory except
for the change of the pressure equalizer or the overvoltage protections.
8.1 INTERFERENCE AT MBS UNIT
This alarm is monitored in the NMS management and configuration module. See the infrastructure
event list (F067516PT).
Any interference in the MBS Unit is activated when there are a large number of consecutive
reception faults in the MBS Unit. A reception fault is considered when a level higher than the threshold for
reception of the carrier, but is not recognized as valid TETRA signal. Depending on the signal level,
interference is considered low or high. So, if the level of signal is above the threshold for reception and below
the threshold set to high interference and is not recognized as a valid sign, it will be a low interference alarm.
If the signal level is above the threshold set to high interference and is not recognized as a valid signal, the
low level alarm would disappear (if it happened) and high interference would produce.
These alarms are turned off when the interference source disappears or with any right TETRA
reception for low interference case, and with more than one consecutive right reception for high-level
interference.

8.2 OVER VOLTAGE PROTECTION
MBS Unit has several protections against lightning and surges, in any case the action of these
protections generate an alarm in the NMS client which disappear when the protective element is replaced by
authorized technical staff.
Protection against lightning and power surges
This protection is located within the MBS Unit. It should be changed every time it breaks
even if the MBS Unit continues functioning properly. An alarm in the NMS Client is reported
showing that the replacement of this type of protection is needed.
Protection against lightning and surges in the RF connections
RF surge protection consists of replaceable Gas Discharge Tubes (GDT) located into the RF
connectors located in the bottom of the MBS. Without GDT no protection is provided and
VSWR performance is degraded.
The GTD is removable, making easy and quick replacing if it is damaged. The replacing
intervals depend mainly upon the number and the strength of the lightning impacts but as a
general rule, must be changed after that a lightning has destroyed some elements ahead
(e.g. antenna). That is why the GTD rarely must be replaced in most use cases and life
expectancy can be up to 20 years.
GDT is connected in parallel between the central conductor and the external shield. During
an overvoltage (lightning), the tube is practically shorted and avoids overvoltage input into
the MBS. When the overvoltage disappears, GTD returns to its original condition of high
insulation and is ready to operate again.
While GTD is triggered (during lightning), the MBS may appear alarmed in the NMS client
software (alarm monitoring of the system).
