1. REGULATORY AND SAFETY INFORMATION
1.1 MAXIMUM PERMISSIBLE EXPOSURE LIMITS
DO NOT TRANSMIT with this base station and antenna when persons are within the MAXIMUM
PERMISSIBLE EXPOSURE (MPE) Radius of the antenna. The MPE Radius is the minimum distance
from the antenna axis that ALL persons should maintain in order to avoid RF exposure higher than the
allowable MPE level set by the FCC.
FAILURE TO OBSERVE THESE LIMITS MAY ALLOW ALL PERSONS WITHIN
THE MPE RADIUS TO EXPERIENCE RF RADIATION ABSORPTION, WHICH
EXCEEDS THE FCC MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMIT. IT IS
THE RESPONSIBILITY OF THE BASE STATION OPERATOR TO ENSURE THAT
THE MAXIMUM PERMISSIBLE EXPOSURE LIMITS ARE OBSERVED AT ALL
WARNING
TIMES DURING BASE STATION TRANSMISSION. THE BASE STATION
OPERATOR IS TO ENSURE THAT NO BYSTANDERS ARE WITHIN THE RADIUS
LIMITS.
1.2 DETERMINING MPE RADIUS
THE MAXIMUM PERMISSIBLE EXPOSURE RADIUS is unique for each site and is determined at
during site licensing time based on the complete installation environment (i.e.. co-location, antenna type,
transmit power level, etc.). Determination of the MPE distance is the responsibility of the installation
licensee. Calculation of the MPE radius is required as part of the site licensing procedure with the FCC.
1.3 SAFETY TRAINING INFORMATION
YOUR M/A-COM MASTR III BASE STATION GENERATES RF
ELECTROMAGNETIC ENERGY DURING TRANSMIT MODE. THIS BASE
STATION IS DESIGNED FOR AND CLASSIFIED AS “OCCUPATIONAL USE ONLY”
MEANING IT MUST BE USED ONLY IN THE COURSE OF EMPLOYMENT BY

5. SITE PREPARATION
5.1 INTRODUCTION
Before you install a MASTR III ADC Base Station, you need to prepare your site. Consider the
installation of the antenna system, space requirements, and weight. These issues are addressed in this
chapter.
This chapter is divided into the following sub-sections:
• Facility Preparation
• Power Installation
• Inter-Site Communication
• Protective Grounding
• Antenna System
• Power Up Sequence
MM102554V1 REV B
5.2 FACILITY PREPARATION
This section provides information for preparing the facility prior to receiving or installing the MASTR III
ADC Base Station equipment.
5.2.1 Floor Plan
When creating the floor plan for cabinet placement, ensure consideration is given to safety, lighting, fire
suppression systems, access to other equipment and storage facilities in the room, etc.
5.2.2 Equipment Cabinet Placement
Direct access (for antenna cables and personnel) between the tower and the equipment room is necessary
for installation purposes).
The equipment cabinet you plan to install should be in an area that is:
• A dedicated equipment room or closet, wired in accordance with local electrical codes
• Large enough to allow easy access for service and maintenance
• Free of dust, smoke, and electrostatic discharge
• Properly ventilated
• Well lighted
The recommended aisle spacing is 29.5 in. (750 mm).
NOTE
19
MM102554V1 REV B
5.2.3 Ceiling Requirements
Consider the following ceiling requirements before you install the equipment cabinet:
• The ceiling should be clear of obstructions such as beams, heating and air conditioning ducts, water
pipes, and lights.
• The ceiling should not have sprinklers; however, appropriate fire protection devices should be
available.
5.2.4 Size and Weight Considerations
Before you install the equipment at your site, make sure that the equipment room can accommodate the
size and weight of the cabinet and the MASTR III ADC Base Station. To determine the total weight, add
the weight of the radio system (about 150 lbs, 68 kg for each radio system), and the weight of the rack.
Typical equipment size and weight is listed in the Specifications section. For the specific weight of
individual units or optional equipment, you should refer to the applicable maintenance manuals or product
Data Sheets.
5.2.5 Operating Environment
The equipment room or area where the MASTR III ADC Base Station is installed must meet the
environmental conditions listed in the Station Specifications section of this manual. In addition, the site
grounding must conform to the requirements of the Standards for Site Grounding and Protection manual
AE/LZT 123 4618/1.
Although the temperature requirements for individual components may be broader, when several units are
assembled together in a cabinet more heat is generated. Because of this condition, the ambient room
temperature outside the cabinet must be lowered to ensure the temperature inside the cabinet does not
exceed the limits for the equipment.
5.3 POWER INSTALLATION
In all cases where the customer provides a single AC supply input to a site, for AC or DC systems, the
input must be protected with a Joselyn AC protector, or equivalent. The AC Protector is installed after
the disconnect switch and must be connected to the external ground system.
If the AC supply is provided from wall outlets, the fuse panel breaker for the room must be sized for the
load of the proposed equipment that is to be installed in the site.
5.3.1 Existing Input Power
If the site already has an existing input power source, then the installers and a certified electrician should
ensure the power meets site requirements and is equipped with the necessary breakers to conform to both
design and local regulatory standards.
If the site input power source does not meet the site requirements or is not equipped with the necessary
breakers to conform to both design and local regulatory standards, refer the matter to the Site Manager.
20
MM102554V1 REV B
5.3.2 AC Distribution
If the site requires an AC distribution system to be installed, ensure it installed by qualified installers in
agreement with the customer. The Applications Engineer will provide the Site Manager with drawings
containing the installation requirements.
Ensure the input supply is isolated and power is not applied until the installation is complete.
5.3.3 Generator System
If the system already has a backup generator system providing backup supply to the site, inspect and test
the generator as defined in the equipment manuals.
Sites equipped with generator systems will use a manual or an automatic transfer switch system. Inspect
the customer system to ensure that it is fitted with the appropriate transfer switch system. This is to be
inspected and tested as defined in the equipment manuals.
If a new generator system is being installed, ensure it is installed by qualified generator installers in
agreement with the customer. When installing generator system remote controls, ensure that the installer
thoroughly understands the application and necessary generator connections. The Applications Engineer
will provide the Site Manager with drawings containing the installation requirements.
5.3.3.1 Manual Transfer Switch
If a Manual Transfer Switch is to be installed, the same team who installed the generator should install the
transfer switch. If this is an additional or new feature, the system is to be modified by qualified engineers
in agreement with the customer. The Applications Engineer will provide the Site Manager with drawings
containing the installation requirements.
5.3.3.2 Automatic Transfer Switch
If an Automatic Transfer Switch is to be installed, the same team who installed the generator should
install the transfer switch. If this is an additional or new feature, the system is to be modified by qualified
engineers in agreement with the customer. The Applications Engineer will provide the Site Manager with
drawings containing the installation requirements.
5.3.4 AC-DC Supply
If the system already has an AC-DC conversion system that meets the system requirements, then inspect
and test the system as defined in the equipment manuals.
If the site requires an AC-DC conversion system to be installed, this is to be performed by qualified
installers in agreement with the customer. The Applications Engineer will provide the Site Manager with
drawings containing the installation requirements.
The system will normally include input circuit breakers, a rectifier stage, converters and individual output
circuit breakers. These components will have their voltage and/or current specified on the site design
drawings. Ensure that input supply is isolated and not re-apply power until installation is complete.
21
MM102554V1 REV B
5.3.5 Battery Backup
A Battery backup system is normally installed to ensure smooth supply voltages during normal operation
or in the event of an input power failure.
If the site already has a battery backup system that meets the system’s requirements, then inspect and test
as defined in the equipment manuals.
The battery backup system will normally be a battery cell system. The backup battery system capacity
should be sufficient to provide the radio system with the desired voltage for a specified time. This should
also include power needed for the inverter equipment, input and output breakers, and either manual or
automatic switches to switch the system into circuit. The installation requirements will be in the site
design drawings agreed to by the customer and Application Engineer.
5.3.6 UPS
An Uninterruptible Power Supply (UPS) system may be an alternative to other backup supply options. It
may comprise some or all of the following components:
• Input supply and protection
• Various DC outputs (additional equipment that is required)
• Output protection
• Battery backup
• Bypass switch
• Automatic switch-over to generator
If the site already has an UPS system that meets the system requirements, then inspect and test the UPS as
defined in the equipment manuals.
If the site requires an UPS system to be installed, ensure the installation is made by a qualified installer in
agreement with the customer. The Applications Engineer will provide the Site Manager with drawings
containing the installation requirements.
5.3.7 Electrical Power
5.3.7.1 AC Power
Each MASTR III cabinet is equipped with its own AC power cord. Each of these power cords should be
connected to a separate circuit breaker. The following circuit breakers are recommended.
• 115 VAC (60 Hz) - a 20-amp circuit breaker for each power cord.
• 230 VAC (50 Hz) - a 15-amp circuit breaker for each power cord.
Receptacles must be installed within reach of the power cords and should be individually fused. They
may be installed on the wall behind the cabinets, in the floor under the cabinets, on the cable ladder above
the cabinets, or in the cabinet top cable ducts. The power cords must not be installed such that they cause
a hazard to persons in the site.
AC Power Installation must conform to local Installation Regulations.
22
MM102554V1 REV B
5.3.7.2 DC Power
When required, DC power options are available, but will be customized for the particular system. The
power supplies will be omitted from the cabinets and replaced by a fused DC panel. In this case, power
must be supplied to the repeaters from an external 13.8 or 24 VDC power source through a separate 30amp circuit breaker for each repeater.
The supply system will normally consist of an AC to DC converter, a Circuit Breaker Panel and various
DC-DC Converters sized for the equipment. DC feeds to the equipment that will be direct from the circuit
breaker panel.
5.3.7.3 Generators
Some systems, predominately remote sites, will require emergency generators with automatic switchover
systems. The generators must be connected to the external site grounding system and should be located
external to the equipment room.
Automatic switchover systems must be disabled during installation.
5.3.7.4 Battery Backup
Some systems will require a battery backup connected to the supply system in case of input power failure.
The battery bank should be located either separate from the equipment room or within the room but at a
point furthest from the entrance. It should have a separate fume extraction system or should be located
below the air extraction system for the site.
5.4 INTER-SITE COMMUNICATIONS
There are various types of Inter-Site Communication Systems, which require interfaces to be pre-installed
within the site. These interfaces will be the agreed demarcation points to which the Customer, SubContractor and system installer will make connections.
There are three types of inter-site connections:
• Hardwire Installation
¾ Direct Connection
• Leased Line
¾ Leased or Dedicated Telephone Line
• T1 or E1
¾ Leased T1 or E1
¾ Microwave
¾ Fiber Optic Cable
5.4.1 Hardwire Installation
When the media specified is to be Hardwire, that is point-to-point wiring on-site, the following
specifications apply:
23
MM102554V1 REV B
• Audio: 2-wire or 4-wire shielded cable; screen connected to site ground system and cable core is to be
solid in order that it may be punched-down.
• Data: Shielded twisted pair, shield connected to site ground system and cable core is to be solid in
order that it may be punched-down.
5.4.2 Leased Telephone Lines
When the media specified is to be Leased-Line via the local telephone company, request a 4-Wire 43202
Type 5 Data-Grade line from the local or regional telephone carrier. If using an equivalent line (old
specification is 3002 Data Grade), it must meet the following specifications:
• Frequency response:
1000 Hz Reference
500 - 2400 Hz -1 to +3 dB
300 - 2700 Hz -2 to +6 dB
• Max Frequency Error = ±5 Hz
• Max Net Loss = 16 dB
• Max Group Delay (800-2400Hz) = 2000µS
• Min S/N Ratio = 24 dB
The Telephone Company or customer will provide a point of interface for the telephone system within the
site known as the Demarcation Point. The installer will make necessary connections between the
Demarcation Point and the equipment
5.4.3 T1 or E1 Links
A T1 or E1 link may be leased from the Local or Regional Telephone Carrier. The physical link may be
via a Microwave System or via Fiber Optic cable. The Microwave or Fiber Optic system may also be
provided by the customer or sub-contracted from an alternate provider.
5.4.3.1 Leased T1/E1
If the link is Leased-Line T1 or E1, the carrier may provide the Multiplex (Mux) equipment and Channel
Service Unit (CSU). If so, they will connect to an agreed Demarcation Point (Punchblock) and collect the
data and modem audio as appropriate. If they do not provide the Mux or CSU, a Mux and CSU will be
provided and the demarcation point will be the appropriate T1/E1 interface on the Mux or CSU.
5.4.3.2 Microwave
The Microwave system may be provided by the Customer, M/A-COM, or a Sub-Contractor. Whichever
is the case, the Inter-Site Communications System should be in place prior to equipment installation and
the system provided will have a Demarcation Point to which the installer will connect the Inter-Site
Communications. This may be Punchblocks or the input connection to the multiplexer and the length of
the cross-connect cabling must be calculated to allow for the agreed location of the interface.
It is normal for the microwave radio to be close to its antenna and, in some installations, this may mean
some distance between radio and multiplexer. If the distance between radio and multiplex equipment is
excessive, consideration must be given to type of cable used for the connection, cable shield/ground,
24
grounding through in-building cable routes, etc. This subject is to be discussed with microwave provider
and must conform to local installation regulations.
5.4.3.3 Fiber Optic
It is a requirement that the demarcation point for fiber optic cable is the fiber optic interface on the
multiplexer. If the multiplexer is not equipped with such an interface, a fiber optic line driver will be
provided and will be the point to which the cable is to be connected.
All other considerations are as for Microwave.
5.5 PROTECTIVE GROUNDING
For information on protective grounding outside the equipment room and general information for internal
grounding refer to the Site Grounding and Lightning Protection Standard manual AE/LZT123 4618/1.
However, a general rule for the external grounding system is that the resistance to ground should be five
(5) ohms or less, as measured with a Biddle DET2/2 Megger or equivalent, per IEEE STD 81-1983 or
local equivalent.
All equipment that is within the site must be connected to an internal halo ground of No. 2 AWG copper
wire six (6) inches below the ceiling. This interior halo ground must be connected to the external ground
system at each corner, using separate No. 2 AWG copper wires. The halo may be mounted on the cable
ladder, in the ducting or beneath the false floor.
MM102554V1 REV B
All metal (electrically conductive) objects within the equipment room must be grounded. These objects
are divided into the following three (3) groups.
• Room Fixtures
• Power Supply
• RF equipment
All metallic fixtures and room parts, such as doorframes, sheet metal, ventilation louvers, air conditioning
units, light fixtures, etc., should be connected to the internal halo ground.
In addition to all other AC power protection, the AC power must be equipped with a Jocelyn AC
protector, or equivalent, placed immediately after the main disconnect switch. This protector must be
connected to the external ground system using a separate No. 2 AWG copper wire.
All equipment cabinets, cable trays, and protectors for cables connecting to this equipment must be
connected to a single grounding plate or bulkhead panel mounted on the wall where the antenna cables
enter the equipment room. This grounding plate must be connected to the external ground system using
two (2), two-inch wide copper strapping, or equivalent. A separate No. 6 AWG copper wire must be used
for each cabinet, each cable tray/ladder, and each group of cable protectors.
A few general rules of thumb are as follows:
• Make ground wires as short as possible and direct as possible - avoid bends if possible - absolutely no
bends with a radius of less than eight (8) inches.
• Surface area of ground wires is more important than cross sectional area.
• All connections must be clean, free of non-conductive coatings, and be coated with an anti-oxidant.
25
MM102554V1 REV B
5.6 ANTENNA SYSTEM
This section covers installing the antenna system, including RF cables from the antenna to the equipment
room wall feed through connector.
Refer to LBI-39185 for Tower Requirements and General Specifications.
NOTE
Crews trained and equipped for working on antenna towers generally install antenna systems. As a result,
this manual assumes crews with the specialized equipment and skills required for working on towers and
installing the antenna cables will install the Antenna Systems. However, it may be necessary for the
system installer to provide information and directions to the crew installing the antenna system and to
verify proper installation.
5.6.1 Antenna Mounting
The antennas must be installed on the tower in such a way as to ensure that there is at least 25 dB of
separation between the TX and RX antennas. This is necessary to avoid interference in the receivers
caused by the transmitters. An isolation of greater than 25 dB is easily obtained by placing one antenna
directly above the other on the tower (minimum 10-foot separation).
26
MM102554V1 REV B
Figure 5-1: Antenna System Requirements
5.6.2 Transmission Lines
When installing the transmissions lines, refer to the block diagram for UHF and 800 MHz Antenna
Systems contained in LBI- 38983.
5.6.2.1 Length
The length of the main coaxial cable for each antenna should be planned as a continuous run with no
connectors or splices between the antenna and the equipment room. Each cable includes a 50-foot
allowance for the distance from the bottom of the tower to the equipment room. Smaller diameter, more
flexible coaxial cables are used at both ends of the main coaxial cable to facilitate installation.
27
MM102554V1 REV B
5.6.2.2 Minimum Bending Radius
Always adhere to the minimum bending requirements provided by the manufacturer. For Andrew
Products, the values are:
CABLE SIZE BENDING RADIUS
1/4-inch 1-inch (25 mm)
1/2-inch 1.25-inch (32 mm)
7/8-inch 10-inches (250 mm)
1 5/8-inch 20-inches (510 mm)
5.6.2.3 Hoisting Grips
Hoisting grips provide the means to attach a lifting mechanism to the coaxial cable without damaging the
cable. Each hoisting grip is capable of safely lifting 200 feet of cable without causing damage.
Therefore, one hoisting grip is required for every 200-foot section of cable. The grips may be left
attached to the cable after the cable installation is completed.
Some situations may require more hoisting grips, such as:
• When installing cables on a tower mounted on top of another structure.
• When installing a cable whose length is greater than the height of the tower.
In these situations, additional hoisting grips should be ordered.
5.6.2.4 Hangers and Adapters
Coaxial cables on the tower should be secured at intervals of 3-5 feet (maximum).
Securing 7/8-inch and 1-5/8-inch diameter coaxial cables is accomplished by using either hangers or
hanger-adapter combinations. The hangers secure the cables to the tower structure by using prepunched
holes or attachment adapters.
• When the tower structure is prepunched with 3/4-inch holes, snap-in hangers are used (preferred
method).
• When the tower is prepunched with 3/8-inch holes, the hanger is secured by a 3/8-inch bolt.
For towers without prepunched holes, the hangers are attached with adapters. The type of adapter
depends on the type of tower structure. Adapters are available for either angle tower members or round
tower members.
Adapters for each antenna system are selected when ordering the system. If the coaxial cable must be
attached to a structure that is not compatible with any of the above hangers or adapters, then additional
materials or other special considerations may be required
To secure 1/4-inch or 1/2-inch vertical or horizontal coaxial cables of any size, use nylon cable ties.
28
5.6.2.5 Weatherproofing
A kit of weatherproof tape is provided to protect coaxial connectors from the outside elements. One roll
of tape is sufficient to weatherproof four exposed outside connector joints.
5.7 QUALITY AUDIT
5.7.1 Antenna System
After the Antenna System is installed, it should be inspected before the installers leave. A checklist of
tasks performed on the antenna system is provided in section 12.3. Be sure to complete this visual
inspection before
Using field glasses, if necessary, view the Antenna System from various positions on the ground. Using
copies of the Antenna System Installation Checklist 12.3, fill out a checklist for each antenna as you go
through the following inspection procedure. This will provide a record of the inspection, and of some
antenna information for future reference.
• Record the make of antenna.
• Record the type of antenna (omni or directional).
the installers leave, so any obvious errors can be corrected.
MM102554V1 REV B
• Record the design gain of the antenna.
• If the antenna is directional, record the bearing of the main lobe. If it is omni, write "Omni" in the
data entry line.
• Record the height of the antenna above ground.
• Confirm that cable-hoisting grips were installed as required to prevent damage to the coaxial cable.
Hoisting grips should have been installed at the antenna end of the cable plus one for each 200 feet of
cable length.
• Confirm the cable is secured to the tower at intervals, which do not exceed 3 feet.
• Confirm the cable is grounded at the top of the tower.
• Confirm the cable is grounded at the point where it leaves the tower.
• Confirm the cable is grounded at the point where it enters the building.
• Confirm the coaxial cable run looks OK. The cable must be tight (nothing to flap in the breeze), have
no kinks, is one continuous run (no connectors or splices), and not exceed the minimum-bending
radius on any bend.
• Confirm the cable feed through is properly installed where the cable enters the building.
• Confirm the coaxial connectors have been properly weather sealed with tape.
• Confirm the cable entrance to the building has been properly weather sealed.
