1.1 Safety Precautions
Listed below are the safety precautions to be satisfied, prior to the outdoor antennas installation:
•Outdoor antennas and antenna cables (good conductors of electricity) should be installed properly to avoid the
transients or electrostatic discharges (that occur due to lightning during thunderstorm) from damaging your
equipment and causing personal injury or death to the persons touching the exposed metal connectors of the
equipment.
•When installing, disconnecting, or replacing one of the cable components, ensure that each of the exposed metal
connectors of the antenna cabling system are grounded locally.
•Do not install the antenna, where there is a possibility of contact with the high-voltage arc-over from the power
cables or service drops to the buildings. Ensure that the antenna-mast or antenna-tower are not close by any power
line, during the installation or removal of antennas.
•Apply a Danger label on a plainly visible area of the antenna support structure.
•Do not climb the rooftops during a thunderstorm, in wet or windy conditions, or on the equipment installation area
which is covered with ice or snow.
•Do not touch the antennas, surge arrestors, or antenna cables during a thunderstorm.
•Install the antennas at a safe distance (at least twice the height of the antenna-mast plus the antenna) from power
lines or telephone lines.
•Mount the antennas at a safe distance, avoiding any human contact during the normal equipment operation.
•Ensure that the human proximity to the antenna is atleast 50 cm (8 inches) high, avoid the possibility of exceeding the
FCC radio frequency exposure limits, during the normal operation of the equipment.

Antenna Installation
Tsunami®800 and 8000 Series - Antenna Installation Guide 8
•Verify that the low-loss antenna cable used to connect the antenna with the surge arrestor, or the ethernet cable used
to connect the surge arrestor, are at least 1 m (3 ft.) away from any high voltage current cable.
•Check whether the antenna mast and its guy wires or wall bracket are positioned correctly and secured properly to the
roof or walls. Also, ensure that the base area, where the antenna-mast is mounted is weatherproofed.
•Ensure, that the grounding system for the antenna mast and the surge arrestor have been installed. The grounding
system must comply with the local electrical code and other requirements. See Grounding the Antennas
•Always consult an experienced electrician to assure that the antenna mast, surge arrestor, and the equipment
hardware are grounded properly.
•The antenna cable between the antenna and the surge arrestor should be grounded. Ensure that the exposed metal
connector of the cable is grounded locally, if the cable is disconnected at one end (disconnected to replace the surge
arrestor).
1.2 Installation Process
Follow the following step-by-step procedure to install outdoor antennas:
1. Ensure that all the materials, essential to install the outdoor antennas are acquired. See Required Materials.
2. Once you have acquired all the required materials, refer Quick Installation Guide (that comes along with your product)
to mount the outdoor equipment and begin the outdoor antenna installation.
3. Verify the optimal antenna placement, maintaining a clear line-of-sight. See Determining the Optimal Antenna
Placement.
4. Mount the antenna to the support structure, following the guidelines as described in Mounting the Antenna.
5. Verify that the device, support structure for antenna (antenna-mast) and entire cable set-up for the antenna are
connected properly. See Connecting the Cables.
6. Connect the antenna cable to the antenna. See Connecting the Antenna Cable.
7. Ensure that the cabling of ethernet / power cables and the surge arrestor is proper. See Connecting the Surge
Arrestor and Ethernet / Power cables
8. Ensure that the antennas are grounded properly to the grounding system, satisfying the local electrical code
requirements. See Grounding the Antennas
9. Once the antenna is properly positioned, grounded and the outdoor cable setup is verified, secure all the cables and
use weatherproofing tape to seal all the outdoor connectors. See Sealing the Cable Connectors.
10. Make sure that the outdoor antennas at both the ends maintain the same antenna polarizations. See Step 4: Next,
wrap a layer of the butyl mastic tape on the adhesive side.
11. Align the antennas to establish a wireless link with a better throughput, by using device antenna alignment utilities
like Audible Antenna Alignment and Antenna Alignment using CLI commands. See Aligning the Antenna.
:For easy outdoor antenna installation, note the following:
•Go through the Safety Precautions.
•Read all the requirements outlined in this chapter. See Required Materials.
•Familiarize yourself with the antenna and the radio-specific mounting instructions, prior to climbing any roof or
ladder.
•Verify that you have arranged all safety measures for outdoor installation or rooftop installation. See Safety
Precautions.
•Test all the equipment before beginning the actual rooftop installation, to determine if all the required equipment is
functioning properly.

Antenna Installation
Tsunami®800 and 8000 Series - Antenna Installation Guide 9
•Install the grounding system for the antenna mast, device, and surge arrestor before connecting the cables. This
protects your system against lightning strikes during installation.
•When you remove or relocate the antenna, verify the Required Materials and Safety Precautions, before you
restart the installation process, and follow the above steps in exactly the reverse order.
1.2.1 Required Materials
The outdoor installation of the equipment and the antennas, require the following:
•An outdoor radio unit.
•An outdoor antenna, supporting the local electrical code.
•A low-loss antenna cable.
:We recommend you to use a coaxial antenna cable (P/N CBL-5054-600-6), that is available with your
distributor.
•Antenna mast or wall bracket for the antenna/device.
•A grounding system that meets the local electrical code. See Grounding the System
•Weatherproofing kit for sealing all the cable connections. See Sealing the Cable Connectors
•Tools and material to mount the antenna. See Mounting the Antenna
•Tape or wraps to attach the antenna cable to the mast.
•Ethernet cable (RJ 45 cable / CAT5e or CAT6 cable) with waterproof cap.
•Proper tools for system installation.
•Ethernet Surge Arrestor and Surge Protector (RF-cable). See Connecting the Surge Arrestor and Ethernet / Power
cables
Ensure that you have acquired all the materials listed above, to begin with the outdoor antenna installation. Refer to the
Quick Installation Guide, that comes along with your product, for details on mounting the outdoor equipment.
1.2.2 Determining the Optimal Antenna Placement
To achieve the maximum throughput, the outdoor antenna must have clear line-of-sight with the antenna at the other end.
The outdoor antennas are said to have a clear line-of-sight, when there are:
•No obstacles in the direct path between the antennas (antenna beam)
•No obstacles within a defined zone around the antenna beam
Although, the radio signal can work well without the clear line-of-sight in urban environments, where the signal is
transported by reflection rather than transporting it directly along the obstacles. The following figure shows some typical
examples of obstacles you must avoid in urban environments, for the directional antenna to operate effectively.

Antenna Installation
Tsunami®800 and 8000 Series - Antenna Installation Guide 10
Figure 1-1 Obstacles to be avoided : (a) Neighbouring Buildings (b) Tall Trees (c) Power Lines
To minimize the signal interference or reflections due to obstacles, note the following guidelines:
•Mount the antenna as high as possible above the ground to allow maximum clearance.
— In open areas, ‘ground’ is the actual surface of the earth.
— In dense urban areas, ‘ground’ is to be interpreted as the height of the highest obstacle in the signal path
between the two antenna sites.
•Avoid trees in the signal path to avoid signal absorption due to seasonal changes (leaves or ice).
•Install the antenna at least 2 m (6 ft.) away from all other antennas.
Other situations in which reflections of the radio signal may cause interference are environments with large reflecting
surfaces, parallel or partly perpendicular to the antenna beam, such as:
•Mirror-glass buildings.
•Crowded parking lots.
•Water surface, moist earth and moist vegetation.
•Electric power lines and telephone lines above the ground level.
:Reflective surfaces can be used to improve the performance of a link, if the direct line-of-sight is impaired or absent.
In the absence of a direct path or clear line-of-sight, transporting a signal through reflection depends on two factors:
•Fresnel Zone: It is required to calculate the distance of the obstacle from the antenna. See Fresnel Zone
•Clearance Factor: It is required for optimal performance (See Clearance Factor). Ensure that the type and placement
of the antennas leave sufficient clearance of the Fresnel Zone at the maximum width of the bulge, which is typically at
the mid-point between the antennas.
1.2.3 Mounting the Antenna
Mounting an antenna directly to the wall does not let you align the antenna properly with the corresponding antenna at the
opposite end of your wireless link. Poor antenna alignment typically results in poor performance and therefore, we
recommend mounting the antennas to a mast.

Antenna Installation
Tsunami®800 and 8000 Series - Antenna Installation Guide 11
The two methods followed frequently to erect an antenna mast are:
•Tripod Mount: The tripod mount is used primarily on peak and flat roofs. The antenna mast must be secured to the
roof using three or four guy wires equally spaced around the mast. When the height of the antenna mast is more than
3 meters (10 ft.), you should use at least three guy wires for every 3-meter (10-foot) section of the mast.
•Wall (Side) Mount: A wall (side) mount allows you to mount the antenna (mast) on the side of a building or on the
side of an elevator penthouse. This provides you with a convenient mounting location, when the roof overhang is not
excessive or when the location is high enough to provide a clear line-of-sight.
When mounting multiple antennas on a single mast, use the following methods to minimize the influence of cross-talk
interference between the antennas:
– Place your antennas as far as possible.
– Mount the directional antennas, such that the identical side of both the antennas face the same direction.
– For 8xxx connectorized unit, use the antenna port A1, if you are using a single polarized antenna. Use the antenna
port A1 and A3, if If you are using a dual polarized antenna.
– For 82x connectorized unit, use antenna ports A1 and A2 for dual polarized antenna.
:As the mounting procedures for the various antennas differ from one another, refer to the guide that comes along
with the antenna.
1.2.3.1 Antenna Mast Requirements
To accommodate the antennas, the antenna mast must satisfy the following requirements:
•The construction of the antenna mast must contain sturdy, weatherproof, and non-corrosive material (for example,
galvanized or stainless steel construction pipe).
•Diameter of the mast should be between 35 mm (1.4 inches) and 41 mm (1.6 inches). The diameter of the antenna mast
vary depending on the type of antenna you intend to install.
•The height of the antenna mast must be high enough to allow the antenna to be installed at least 1.5 m (5 ft.) above the
roof. The height of the antenna should be at least 3 m (10 ft.) above, if it is a metal roof.
•The antenna mast or wall bracket must be free from any material (like paint) that prevents a good electrical conduction
with the antenna.
1.2.4 Connecting the Cables
Once the outdoor antennas are properly mounted, the cable setup essential to complete the outdoor antenna installation is
depicted in the following figure:
: The antennas installed at both the ends of a wireless link should maintain same antenna
polarizations. See Step 4: Next, wrap a layer of the butyl mastic tape on the adhesive side.

Antenna Installation
Tsunami®800 and 8000 Series - Antenna Installation Guide 12
Figure 1-2 Cable Setup
The entire outdoor cabling setup requires the following cabling to be done:
1. Connecting the Antenna Cable
2. Connecting the Surge Arrestor and Ethernet / Power cables
3. Grounding the System
1.2.4.1 Connecting the Antenna Cable
Follow the following steps to connect an antenna to the device, by using an antenna cable.
1. Use an RF cable (antenna cable) to connect the outdoor device to an external antenna.
2. Connect the right-angled N-male connector of RF cable on the antenna. The antenna cables run from the external
antenna to the N-Type connectors on the device. The N-Type connectors have built-in surge protection for Tsunami®800
and 8000 product series.
3. Secure the antenna cable to the antenna mast, as the cable connectors do not support the full weight of the cable.
4. Connect the other end of the antenna cable to the device.
: Do not use tools to tighten the cable connectors, as they damage the antenna cable and connectors.

Antenna Installation
Tsunami®800 and 8000 Series - Antenna Installation Guide 13
5. If required, adjust the direction of the antenna.
6. Tighten the nuts of the antenna to lock the antenna into its position.
7. Secure the cable along its complete length with a cable or electrical tape to relieve strain on the antenna connector. No
part of the cable should be allowed to hang free, especially the parts that are routed outside the building.
8. Weatherproof all the outdoor connectors. See Sealing the Cable Connectors
Ensure you follow the below guidelines while using the antenna cable:
•The entire cable used must be secured and no part of the antenna cable should be allowed to hang free, precisely the
outdoor cable parts.
•The antenna cable and cable connectors are not designed to withstand excessive force.
•Do not use the connectors like ‘cable grips’, to pull the cable through raceways or conduits.
— Do not use the cable connector to support the weight of the cable during or after installation.
— Do not use any tool to tighten the connectors.
•Always seal the connectors using the weatherproofing tape.
•Avoid any water or moisture entering the cable, as it impacts the performance of the wireless link.
•Prior to sealing the outdoor connectors and permanently securing the cable to the wall with cable ties and wall hooks,
assure that the components that are installed are functioning properly.
Antenna Cable Routing
The antenna cable must be routed and fixed in such a way, that the installation technicians have a clear passage area. All the
connectors that are located outdoor must have a weatherproof seal. We recommend you to seal the connectors only after
completing the final radio test. See Sealing the Cable Connectors
1.2.4.2 Connecting the Surge Arrestor and Ethernet / Power cables
Perform the following steps to ensure proper surge protection, and ethernet or power cabling:
•Connect the surge arrestor near the outdoor device with a CAT5e/CAT6 ethernet cable (properly ground it near to the
cable ingress point of the building, complying with the local electrical code requirements).
•Connect the RJ 45 ‘LAN-IN’ port on the POE (power injector) and the network interface card of the personal computer
with a CAT5e/CAT6 ethernet cable.
•Plug one end of the Cat5e/Cat6 cable into the ethernet port of the surge arrestor (near building ingress point) and
connect the other end of the cable to the ‘PWR-LAN-OUT’ port on the POE. Ensure that the cable connector is latched
securely.
•Connect the remaining ports on both the surge arrestors (one near the outdoor device and other at the building
ingress point) with an RJ 45 terminated cable.
: Proxim recommends two approved lightning surge protectors to be installed, one near to the device and the other at
the building ingress point. To buy an additional Surge Protector (with Part Number: 235-00001), place an order
separately with your distributor.
: Avoid over-tightening of the connector, nuts and screws that are used to mount the antenna, to
protect the antenna and device from getting damaged.

Following precautions should be satisfied, while grounding the antenna:
•The antenna mast and the grounding system should be installed only by qualified installation professionals and
electrician, who are familiar with local building, safety, and electrical codes in the country of use.
•The antenna mast, the device, and the surge arrestor must be connected to the same ground, by using an equi-
potential bonding conductor.
•A good electrical connection should be made to one or more ground rods, by using at least a 10AWG ground wire
and non-corrosive hardware.
1.2.5 Sealing the Cable Connectors
Corrosion of the antenna cable, cable connectors and other wireless outdoor installations degrade the performance of the
wireless link. To avoid, you must always seal the outdoor cable connectors using weatherproofing tape. To weatherproof the
antenna connectors at both the ends of a wireless link, follow the following step-by-step procedure:
1. Collect the required material:
The material required for weatherproofing connectors are,
•Any standard Butyl Mastic Tape
•Any standard Vinyl Tape
We have used the following Butyl Mastic Tape and Vinyl Tape as an example to demonstrate the weatherproofing steps:
2. Follow the following weatherproofing steps:
: The surge arrestor and the antenna mast must be connected to the same grounding system, by
using the shortest cable possible, as prescribed by local electrical codes.
: We have taken MP-8100-BSU and 16 dBi dual polarized sector antenna as an example to explain the
weatherproofing steps. Follow the same method to weatherproof the antenna connectors of the
Tsunami®800 and 8000 series products.

1.2.6 Antenna Polarization
For optimal wireless link performance, you must always verify that the same antenna polarizations are maintained on both
the ends of a wireless link. Tabulated below are the antenna polarizations for the Tsunami®800 and 8000 product series.
:
•If you are using all the antenna ports of a MIMO device, we recommend you to maintain different antenna
polarizations on both the ends to avoid coupling.
•If you are using a single polarized or dual polarized antenna, it is recommended to terminate the unused antenna
ports with an N-male 50 ohm terminator (supplied with the product package). Refer Tsunami®800 and 8000 Series
- Hardware Installation Guide, for details.

Consider mounting the antenna for horizontal polarization and minimize the influence of cross-talk between antennas, only
under the following circumstances:
•When you are using single polarized antennas at both the ends of a wireless link.
•When multi-directional antennas are mounted to the same mast.
•When the wireless link receives interference from a vertically polarized antenna in the vicinity.
1.2.7 Aligning the Antenna
Antenna alignment is the process of physically aligning the antenna of the radio receiver and transmitter to establish a link
with a better throughput. The antenna alignment process is usually performed during the installation of the antennas. You
can align the antennas by using the following two methods:
•Audible Antenna Alignment
•Antenna Alignment using CLI Commands
Alternatively, consult an antenna installation service professional to optimize the antenna alignment.
1.2.7.1 Audible Antenna Alignment
The device has a built-in audible antenna alignment tool that can be activated by plugging in the supplied RJ11 serial dongle.
It is audible up to a distance of 30 meters. The CLI command enables both audible and numerical feedback as the CLI shows
the running Signal-to-Noise Ratio (SNR) values twice a second.
The output from the beeper consists of short beeps with a variable interval. The interval changes with the SNR level to assist
in correctly aligning the antenna. An increase in signal level is indicated by a shorter interval between beeps and a reduction
in signal level results in longer beeps.
The alignment process averages the SNR, which is represented by an average length beep. When a higher SNR is received, the
beep period becomes shorter, dependent upon the difference to the average. A lower SNR results in a longer period between
beeps.
Figure 1-3 Beep Interval
When the antenna is aimed, the beep intuitively represents whether the SNR is rising or falling. The higher the SNR rises, the
higher is the frequency of the beep and shorter beep is heard. When you change the position of the antenna, SNR averaging
settles at the new value and the beeping returns to the average length so the antenna can again be aimed for rising SNR.
Aiming is complete if moving the antenna in any direction results in a falling SNR value (which can be heard as longer periods
between beeps).

Antenna Installation
Tsunami®800 and 8000 Series - Antenna Installation Guide 20
:
•The range of the average SNR is limited to values from 5 to 43. Anything over 43 always results in a short period
between beeps and values below 5 always have a long period.
•The Antenna Alignment Display (AAD) CLI command is automatically disabled 30 minutes after it is enabled to
remove the load of extra messages on the wireless interface. The default telnet time-out is 300 seconds (5 minutes).
•It is applicable only to 8xxx devices.
1.2.7.2 Antenna Alignment using CLI Commands
To enable the antenna alignment display from the CLI prompt, enter the following commands:
•aad enable local: Enables display of the local signal, noise and SNR.
•aad enable remote: Enables display of the remote signal, noise and SNR.
•aad enable: Enables display of local and remote signal, noise and SNR.
:Use a flat blade screw driver to disconnect and pull out the serial cable from the enclosure after the antenna
alignment is done. After withdrawing the cables, seal the serial port carefully to avoid water seepage.
