ABOUT THE TSUNAMI MP.11A
The Tsunami MP.11a lets you set up a wireless system based upon two basic topologies:
▪ Point-to-point link to connect one location to another
▪ Point-to-multipoint link to connect one location to two or more other locations.
A link between two locations always consists of a Base Station Unit and a Subscriber Unit. A Base Station
Unit can, depending upon its configuration, connect to one or more Subscriber Units; a Subscriber Unit,
however, can connect to only one Base Station Unit at any given time.
Point-to-Point Link
With a Base Station Unit and a Subscriber Unit, it is easy to set up a wireless point-to-point link as depicted
in the following figure.
Figure 1. Point-to-Point Link
The point-to-point link function lets you set up a connection between two locations as an alternative to:
▪ Leased lines in building-to-building connections
▪ Wired Ethernet backbones between wireless access points in hard-to-wire environments
About this Book 6
CPN 65756 Issue Date: 01 August 2003
Tsunami MP.11a Antenna Installation Guide
Point-to-Multipoint Network
To connect more than two buildings, you can choose to:
▪ Set up multiple point-to-point links, using multiple pairs of Base Station and Subscriber Units
▪ Set up a single point-to-multipoint network using a single Base Station Unit and multiple Subscriber
Units, as depicted in the following figure.
Figure 2. Point-to-Multipoint Network
The system in this figure is designed as follows:
▪ The central building (c) is equipped with the Base Station Unit, connected to either an omni-directional or
a wide angle antenna.
▪ The two other buildings (a and b) are both equipped with a Subscriber Unit connected to a directional
antenna.
Note: Depending upon local radio regulations and legislation, the outdoor antenna solutions described in
this document may not be available in all parts of the world. Consult “Appendix C. Certified Outdoor
Solutions” for more information.
About this Book 7
CPN 65756 Issue Date: 01 August 2003
Tsunami MP.11a Antenna Installation Guide
Chapter 1. Preparing for Installation
SITE PREREQUISITES
Review all requirements outlined within the following sections before starting the installation procedure:
▪ Overview of the Indoor Installation
▪ Overview of the Outdoor Installation
▪ Climbing the Roof
Prior to climbing on the roof or any other area where you intend to install the outdoor antenna, you are
advised to:
▪ Verify that you have arranged all safety measures for outdoor or rooftop installation.
▪ Verify that you have all equipment and tools required to install the outdoor antennas.
▪ Install and verify proper operation of the equipment.
OVERVIEW OF THE INDOOR INSTALLATION
The indoor installation of the link consists of the following components:
▪ The Tsunami MP.11a hardware
▪ A cable system
Tsunami MP.11a Hardware
There are three types of hardware devices to setup a wireless link:
▪ Tsunami MP.11a Base Station Unit (BSU)
▪ Tsunami MP.11a Subscriber Unit (SU)
▪ Tsunami MP.11a Residential Subscriber Unit (RSU)
Tsunami MP.11a
The following figure shows an overview of the cable setup for this outdoor antenna. When the MP.11a is not
mounted close to the entrance of the antenna cable into the building (where the surge arrestor must be
mounted), an additional cable between the MP.11a and the surge arrestor is needed, plus a female-female
converter connector. If the MP.11a is mounted close to the surge arrestor, the MP.11a can be connected
directly to the surge arrestor.
The deviation to the rule is the MP.11a RSU when the Window antenna is installed in an indoor location. This
does not require the use of a Surge Arrestor. The antenna can be connected directly to the MP.11a.

Figure 3. Cable Setup for Indoor Installation
On each end of the wireless link you will require the following items:
▪ A Tsunami MP.11a Base Station or Subscriber Unit
▪ A low-loss antenna cable to connect the indoor installation to the surge arrestor (optional)
▪ Female-female converter connector (optional)
▪ A surge arrestor to protect your sensitive Tsunami MP.11a equipment from static discharge and
transients from the outdoor antenna system
▪ A low-loss antenna cable to connect the surge arrestor to the outdoor antenna
▪ Outdoor antenna
▪ A grounding system as described in “Grounding System” on page 16.
Placement of the Tsunami MP.11a Hardware
The electronics (power supply and unit) are designed for indoor mounting and operation. The ideal location
must satisfy the following requirements:
▪ The location provides a connection to a grounding type AC wall outlet (100-240 VAC), using the standard
power cord supplied with the unit. (Alternative power can be provided through Power over Ethernet.)
▪ The ground of the AC wall outlet must be connected to the same grounding system as the surge arrestor
and antenna mast (see “Grounding System” on page 16).
▪ The location must allow for easy disconnection of the Tsunami MP.11a hardware from the AC wall outlet.
▪ The location provides a connection to the network backbone (an Ethernet LAN cable that is connected to
a hub, bridge, or directly into a patch panel)
Chapter 1. Preparing for Installation 9
CPN 65756 Issue Date: 01 August 2003
Tsunami MP.11a Antenna Installation Guide
▪ The location is as close as possible to the point where the antenna cable will enter the building (see
“Placement of the Surge Arrestor” below).
▪ The ideal location has a temperature of 0-55 degrees Celsius and a maximum relative humidity (non-
condensing) of 95%.
CAUTION! The Tsunami MP.11a hardware, the surge arrestor, and the antenna mast must be
connected to the same grounding system.
Cable System
CAUTION! The Tsunami MP.11a products are designed for indoor installation. At all times the
location of the Tsunami MP.11a radio unit and power supply must be indoors, to protect
the unit from extreme weather conditions, excessive heat and humidity, and to keep the
unit free from vibration and dust. The antenna and surge arrestor can be placed
outdoors.
Prior to mounting the Tsunami MP.11a, you are advised to calculate carefully:
▪ The distance between the intended location of your Tsunami MP.11a hardware and the location of the
antenna mast
▪ The height of the antenna on the mast.
If the low-loss antenna cable is not long enough to cover this distance you can select another:
▪ Cable length from the Proxim Systems low-loss cable offering
▪ Location that satisfies the requirements listed previously to mount your Tsunami MP.11a hardware
As the length of the antenna cable may affect the actual range of your outdoor antenna installation, the last
option is preferred.
WARNING! You must not change the length of the low-loss antenna cable to a length shorter than
allowed by the radio’s certifications (see “Appendix C. Certified Outdoor Solutions “on
page 47. Shortening the cable will void the Proxim Corporation warranty and may
conflict with radio certifications or approvals.
How to install the Tsunami MP.11a hardware is described in Tsunami MP.11a Installation and Management,
which comes on the Tsunami MP.11a product CD.
Placement of the Surge Arrestor
The surge arrestor is an indispensable part of your outdoor antenna installation. It protects your sensitive
electronic equipment from transients or electro-static discharges at the antenna.
For optimal protection, the surge arrestor must be installed at a location that satisfies the following
requirements:
▪ A location as close to the location where the antenna cable will enter the building (see “Placement of the
Tsunami MP.11a Hardware” on page 9).
▪ The location allows for easy disconnection of the surge arrestor from the cable connected to the unit.
▪ The location provides a connection to the same grounding system as the Tsunami MP.11a hardware and
the outdoor antenna mast (as described in “Grounding System” on page 16).
Chapter 1. Preparing for Installation 10
CPN 65756 Issue Date: 01 August 2003
Tsunami MP.11a Antenna Installation Guide
Antenna Cable Route
The antenna cable must be connected from the antenna through the surge arrestor to the pigtail connector of
the MP.11a unit. To plan the route of the antenna cable, consider the following:
▪ Does the cable route require drilling through a wall or ceiling?
▪ Do you have a building plan of the desired location showing other cabling routes like electricity,
telephone or networking?
▪ Does the type of building materials require special drilling tools?
The cable should not be installed into tight positions, as bending or applying excessive force to the
connectors can damage the antenna cable. Always allow the cable to bend naturally around corners. The
recommended bend radius is at least 100 mm (4 in) or more for the low-loss cable of 10 mm (0.4 in)
diameter.
The cable must be secured along the complete distance between attachment points. No part of the antenna
cable should be allowed to hang free. This is particularly important for outdoor cable parts.
CAUTION!
▪ The antenna cable and cable connectors are not designed to withstand excessive force:
º Do not use the connectors as ‘cable grips’ to pull cable through raceways or conduits.
º Do not use the cable connector to support the weight of the cable during or after
installation.
º Do not use any tool to tighten the connectors.
▪ Always seal the connectors using weatherproofing tape.
▪ Avoid any water or moisture entering the cable as that 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, you may want to verify whether the installation and all components functions
properly.
Chapter 1. Preparing for Installation 11
CPN 65756 Issue Date: 01 August 2003
Tsunami MP.11a Antenna Installation Guide
OVERVIEW OF THE OUTDOOR INSTALLATION
The outdoor installation of the link (point-to-point or point-to-multipoint) requires the following:
▪ An antenna
▪ A low-loss antenna cable (available in three lengths)
▪ Antenna mast or wall bracket for the antenna
▪ An adequate grounding system that meets the requirements described in “Grounding System.”
▪ Waterproofing of all connections
Note: All outdoor cable connectors must be sealed with weatherproofing stretch tape to make the coax
connectors permanently waterproof. See “Sealing the Cable Connectors” on page 29.
DANGER! For your own safety, the antenna mast and the grounding system should only be
installed by experienced installation professionals who are familiar with local building
and safety codes and the national electrical codes.
Read carefully the instructions described in “Grounding System” on page 16 and verify
that your installation complies with the appropriate regulations and codes before
installing the antenna.
Antenna Placement
To achieve maximum performance of your wireless outdoor link, the outdoor antenna must have clear line-
of-sight to the antenna of the other Tsunami MP.11a unit. Although the MP.11a radio signal can work well
without line-of-sight in urban environments, where the signal is transported by reflection instead of being
direct, the best results are achieved in line-of-sight conditions.
Line-of-sight can be defined as:
▪ No obstacles in the direct path between the antennas (antenna beam).
▪ No obstacles within a defined zone around the antenna beam.
You should be aware that the shape of an antenna beam is not straight and narrow like a laser beam. The
antenna beam, also referred to as Fresnel1 Zone, is rather “bulged” in the middle, such as, for example, a
rugby ball.
The exact shape and width of the Fresnel Zone is determined by the path length and frequency of the radio
signal. The width as distance from the direct antenna beam is approximately 6 m (21 ft) in the middle of the
wireless link for a distance of 6.5 Km (4 mi) and a frequency of 5.8 GHz. This width also is the required
clearance of the antenna beam from obstacles in its path, to avoid loss of radio signal.
If any significant part of this zone is obstructed, a portion of the radio energy will be lost, resulting in reduced
performance. Reduced performance can also occur when obstacles close to the antenna beam cause signal
reflections or noise that interfere with the radio signal.

CPN 65756 Issue Date: 01 August 2003
Tsunami MP.11a Antenna Installation Guide
The following figure shows some typical examples of obstacles that you must avoid for the directional
antenna to operate effectively:
▪ Neighboring buildings
▪ Trees or other obstructions
▪ Power lines
To allow optimal performance you must 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.
Figure 4. Potential Obstacles for a Directional Antenna
To minimize the influence of obstacles, signal interference, or reflections, note the following guidelines:
▪ Mount the antenna as high as possible above the “ground” to allow maximum clearance:
º In open areas, “ground” is the actual surface of the earth.
º 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 where
large reflecting surfaces exist in parallel or partly perpendicular to the antenna beam.
Chapter 1. Preparing for Installation 13
CPN 65756 Issue Date: 01 August 2003
Tsunami MP.11a Antenna Installation Guide
Environments with large reflective surfaces include:
▪ Mirror-glass buildings
▪ Crowded parking lots
▪ Water or moist earth and moist vegetation
▪ Above ground power and telephone lines
Note: The use of reflective surfaces can be used to improve a link, especially if the direct line-of-sight is
impaired or absent.
Weather conditions such as rain or snow usually do not have much impact on the performance of your
Tsunami MP.11a product, provided you have sealed all cable connectors with weatherproofing tape.
Seasonal influence on signal propagation can occur in the following situations:
▪ A marginal communications quality in late fall (with no leaves on the trees in the signal path) might fail in
the summer.
▪ In winter, a wireless link may fail when the antenna is exposed to ice buildup, or when the antenna
elements are covered with snow.
Radio paths over water or extremely flat ground may require optimization of antenna height at one end. This
is due to in-phase or out-of-phase reflections. Adjustment of antenna height by 1 to 3 meters may move the
signal from a null to a peak.
Long distance links may be obstructed b earth curvature, so the antenna height requirements must not only
take the height of obstructions and Fresnel Zone into account, but also earth bulge. The earth bulge is
approximately 5 m (16.4 ft) at a link distance of 16 Km (10 mi).
In these cases consult your supplier to take appropriate steps to maintain or optimize wireless link
performance.
Antenna Mounting
There are two ways to erect an antenna mast: Tripod Mount and Wall (Side) Mount.
Tripod Mount
The tripod mount is primarily used on peaked and flat roofs. The antenna mast must be secured to the
roof using 3 or 4 guy wires equally spaced around the mast. When the height of the antenna mast is
more than 3 meters (10 ft), you are advised to use at least three guy wires for each 3 meters (10 ft)
section of the mast.
Wall (Side) Mount
A wall (side) mount allows for mounting an antenna (mast) on the side of a building or on the side of an
elevator penthouse. This will provide a convenient mounting location when the roof overhang is not
excessive or the location is high enough to provide a clear line-of-sight.
In most situations mounting an antenna directly to the wall will not let you align the antenna properly with
the corresponding antenna at the opposite end of your wireless link. As poor alignment typically results in
poor performance, Proxim recommends always mounting the antennas to a mast. An exception to this
rule is the wide-angle window antenna that can be mounted on a window or wall facing the nearest Base
Station with line of sight.
Chapter 1. Preparing for Installation 14
CPN 65756 Issue Date: 01 August 2003
Tsunami MP.11a Antenna Installation Guide
Antenna Mast Requirements
To accommodate the antennas, the antenna mast must satisfy the following requirements:
▪ The construction of the mast must consist of sturdy, weatherproof, and non-corrosive material such as,
for example, galvanized or stainless steel construction pipe.
▪ Typical diameter of the mast should be between 35 mm (1.4 in) and 41 mm (1.6 in). Depending upon the
type of antenna you intend to install, other diameters also may be possible.
▪ The height of the antenna mast must be sufficient to allow the antenna to be installed at least 1.5 m (5 ft)
above the peak of the roof. If the roof is of metal, the height of the antenna should be at least 3 m (10 ft)
above the roof.
▪ The mast or wall bracket must be free from any substance that may prevent a good electrical connection
with the antenna such as, for example, paint.

CPN 65756 Issue Date: 01 August 2003
Tsunami MP.11a Antenna Installation Guide
Chapter 2. Determining Range and Clearance
When you read about wireless outdoor products, you often encounter the terms output power of the radio
and gain of the antenna equipment as measures for the strength of the transmitted signal.
▪ Output power of radio equipment often depends on maximum limits as defined by local radio regulations;
consequently, output power is, by definition, not the way to enhance wireless performance.
▪ High gain antennas are larger in size than low gain antennas and are characterized by a narrow focus of
the antenna beam. These two characteristics make it more difficult to aim the antennas and adjust
antenna alignment to optimize the performance of the wireless point-to-point link.
The Tsunami outdoor solution is based upon the following principles:
▪ An output power and antenna gain that comply with the maximum limits as defined by local governing
bodies concerning radio transmissions.
▪ Enhanced radio sensitivity for optimal receive quality of radio signals transmitted by remote antennas.
DETERMINING THE OUTDOOR RANGE
The range of your outdoor antenna installation is closely related to a number of different factors. To let you
determine the range of the Tsunami MP.11a antenna system in your situation, we have defined the following
formula:
Range = Maximum Range x Cable Factor x Clearance Factor
where:
Maximum Range Identifies the theoretical maximum that could be achieved under optimal
circumstances using the available Tsunami MP.11a products according to their
specifications and in compliance with local radio regulations.
Cable Factor Identifies a correction value (percentage) that compensates for additional cable
losses related to the type of cables used at both ends of the wireless link. (See
“Cable Factor” on page 17.)
Clearance Factor Identifies a correction value (in percentage) that should be used in case the
signal path of your wireless link does not provide the minimum clearance as
listed in the Maximum Range table. (See “Clearance Factor” on page 18.)
Chapter 2. Determining Range and Clearance 16
CPN 65756 Issue Date: 01 August 2003
Tsunami MP.11a Antenna Installation Guide
Maximum Range
The maximum range of your Tsunami MP.11a system is based upon:
▪ The Type of Outdoor Antenna Equipment
▪ The Data Speed of the Wireless Link
▪ The clearance of the signal path (see “Clearance Factor” on page 18).
The values in this section are based on calculations that assume optimal radio conditions. They do not
represent a guarantee that the same maximum distance can be achieved at your location. Differences in
performance figures may result from:
▪ Incorrect alignment of antennas (see “Antenna Alignment” on page 30).
▪ Polarization mismatch of the antennas.
▪ Sources of interference or unexpected reflections in the signal path that affect the communications
quality (see “Antenna Placement” on page 12).
▪ Severe weather conditions such as heavy rain or snow fall, or strong winds.
▪ Seasonal influences such as leaves on trees, or icing on the antennas.
Cable Factor
Determine the Cable Factor from the following table to calculate the probable range for your installation.

Clearance Factor
For optimal performance of your outdoor wireless link, the signal path between the Base Station Unit and
Subscriber Unit must provide sufficient clearance.
Note: A outdoor wireless link that lacks sufficient clearance will suffer from poor performance, which is
typically perceived as slow network response times. Although your Tsunami MP.11a equipment
automatically retransmits every lost data frame due to an out-of-range situation or frame collision, the
larger the number of retransmissions, the lower the throughput efficiency of your wireless link.
This section explains how to determine the clearance that applies in your environment and (if applicable) the
effect of insufficient clearance on the range of your outdoor wireless link.
In “Chapter 1. Preparing for Installation” on page 8, we described the shape of the antenna beam as being
“bulged” in the middle.
Figure 5. Fresnel Zone
If any significant part of this bulged zone is obstructed, a portion of the radio energy is lost, which can affect
the performance of your wireless link in terms of maximum range and transmit rate.
In Figure 5, you see two variables that determine the shape of the antenna beam, also referred to as Fresnel
Zone:
▪ The distance between the antennas (a)
▪ The clearance required for optimal performance (b), where clearance should be interpreted as:
º Vertical clearance above the ground and the highest buildings or objects in the signal path
º Horizontal clearance from neighboring buildings and objects in the signal path.
For optimal range and throughput performance, you must ensure that your antenna installation provides
maximum clearance in both horizontal and vertical direction.
Chapter 2. Determining Range and Clearance 18
CPN 65756 Issue Date: 01 August 2003
Tsunami MP.11a Antenna Installation Guide
Clearance should be interpreted as follows:
▪ In open areas without obstacles in the signal path, clearance is measured as height above the surface of
the earth. For example, if the antenna is mounted on the roof, this height includes the height of the
building plus the height of the mast above the rooftop.
▪ In areas with obstacles in the signal path between the two antennas, clearance should be measured as
height above the highest obstacle in the signal path.
▪ In dense urban areas, the clearance should be measured as height above the highest rooftop or any
other obstacles in the signal path between the two antennas.
For situations in which local authorities, the proprietor of the premises, or other factors do not let you set up
an antenna mast that lets you meet the listed clearance requirements, you may be unable to achieve a full
line-of-sight clearance. At the same time, however, when the distance that your wireless outdoor installation
must cover is less than the listed maximum range, you may not even need full clearance,.
To determine the effect of insufficient signal path clearance, you must determine the Clearance Factor as
described below, and calculate its effect on the range for your antenna installation using the formula
described in “Determining the Outdoor Range” on page 16.
▪ If the clearance for your antenna installation is equal to or better than the minimum clearance
requirement, the Clearance Factor for your installation is 100%.
▪ If your actual clearance is less than the minimum clearance, use the diagram depicted in the following
figure to determine the actual range that applies in your situation.
Note: The Clearance Factor Diagram should be used as a rule-of-thumb for estimating the probable range
in case the clearance requirements are not fully met. In real life, using FCC approved products, you
will also find it almost impossible to achieve the level of clearance for maximum range.

CALCULATIONS
Availability of the microwave path is a prediction of the percent of time that the link operates without
producing an excessive bit error rate (BER) due to multipath fading. In the absence of direct interference,
availability is affected by the following:
▪ Path length
▪ Fade margin
▪ Frequency
▪ Terrain (smooth, average, mountainous)
▪ Climate (dry, temperate, humid)
Depending upon the type of information carried over the link and the overall network design redundancy, you
may want to design for a specific availability rate. For example, if the data or voice traffic carried by the radio
is critical, the link can be designed for a very high availability rate (for example, 99.999% or 5.3 minutes of
predicted outage per year).
Availability can be improved by increasing the fade margin either by making the path shorter or by using the
higher gain antennas in conjunction with lower loss transmission line (using a higher quality transmission
line, shortening the length, or both).
Calculating Received Signal Level and Link Budget
Use the following formula to estimate the received signal level (RSL):
RSL (dBm) = Pout - L1+ G1 + G2 - L2 - Lp
where:
Pout is the transmitter output power (in dBm)
L1 is the total loss of all transmission elements between the antenna and the RF Unit on one
side of the link (in dB)
G1 is the gain of the antenna on one side of the link (in dB)
G2 is the gain of the antenna on the opposite side of the link (in dB)
L2 is the total loss of all transmission elements between the antenna and the RF Unit on the
opposite side of the link (in dB)
Lp is the Path loss, defined by:Lp (dB) = 96.6 + 20 log10F + 20 log10D
where:
F is the Frequency of the radio system in GHz (5.8 in the case of this model)
D is the Distance of the path in miles
See the following figure for a visual representation of the elements of this equation.
Chapter 2. Determining Range and Clearance 20
CPN 65756 Issue Date: 01 August 2003
Tsunami MP.11a Antenna Installation Guide
Procedure:
1. Start with the transmit power and the number of the channel to be used. From the output power tables
(on page 23) find the dBm associated with this output power and channel.
2. Subtract the total loss of all transmission elements between the antenna and the radio on one side of the
link (dB). (See “Minimum Antenna Cable Loss in 5 GHz Bands” on page 24.)
3. Add the dBi of the antenna you will be using. The total is the EIRP (equivalent isotropically radiated
power).
4. Determine your link budget from the Distance and Path Loss table, For example, if the distance between
the two radios is approximately 5 km, the link budget would be 121. (Note that this is the value for 4.8
km, which is closest to the actual value.)
5. Add the gain of the antenna on the second side of the link.
6. Subtract the total loss of all transmission elements between the antenna and the radio on the second
side of the link. The result is the Received Signal Level (RSL).
7. From the Receiver Sensitivity in Table 2 on page 22, find the dBm value for the data rate used for the
link.
8. Add the “Minimum SNR for a Good Link” value of the data rate in use to the Receiver Sensitivity level.
9. Subtract this value from the Received Signal Level; this is the Fade Margin.
Chapter 2. Determining Range and Clearance 21
CPN 65756 Issue Date: 01 August 2003
Tsunami MP.11a Antenna Installation Guide
Notes:
▪ The RSL must be higher than the Receiver Sensitivity plus the minimum SNR for a good link. See Table
3 on page 23, to have a working link with no excessive errors. The amount of Fade Margin indicates the
reliability of the link; the more Fade Margin, the more reliable the link.
▪ The path loss must be smaller than the link budget minus the minimum required fade margin. The
maximum ranges cause the path loss plus the fade margin to be the same as the link budget.
The results of this link budget calculation are very important for determining any potential problems during
installation. If you have calculated the expected RSL, you can verify that it has been achieved during
installation and troubleshooting, if necessary.
In the USA and Canada, this model radio can be installed with any gain directional antennas, as there is no
Effective Isotropic Radiated Power (EIRP) limit for the application of these systems for fixed point-to-point
applications. In other countries, EIRP limits may apply.
In the case of EIRP limits, use the lesser of either (Pout - L1+ G1) or the EIRP limit within the previous
equation. You should check this equation in both directions to assure legal application.
An EIRP limit is the maximum RF energy that can be transmitted, as measured at the transmitting antenna,
and is usually determined by government regulations.

The first Fresnel zone size is a list; Proxim’s recommendation is to keep at least 60-70% of this zone free. If
the clearance is lower than this percentage, the link budget and achieved fade margin are affected.
Clearances more than 100% of the Fresnel zone can cause reflections that are 180 degrees out of phase
and can cancel out the signal. The Fresnel zone works in both the horizontal and vertical paths.

Tsunami MP.11a Antenna Installation Guide
Chapter 3. Installing the Antenna
PLANNING ANTENNA INSTALLATION
Plan the day for your outdoor antenna installation carefully. Do not install the antenna in wet or windy
conditions, during a thunderstorm, or when the area in which the equipment is to be installed is covered with
ice or snow.
The grounding system for the antenna mast, Tsunami MP.11a hardware, and surge arrestor should be
installed before the cable from the antenna is connected to the surge arrestor. This protects your system
against lightning strikes during installation.
Familiarize yourself with the antenna and the antenna-specific mounting instructions prior to climbing any
roof or ladder. Installing and testing all equipment before beginning the actual rooftop installation will help
you to determine whether all required equipment and items are available and are functioning properly.
To verify the equipment prior to installation, you may need to follow the guidelines as described in the
documentation that comes with the Tsunami MP.11a first.
SAFETY PRECAUTIONS
Read this section carefully before beginning the installation. All of the following requirements should be
satisfied prior to starting installation of your outdoor antennas.
DANGER!
The Tsunami outdoor antennas are intended for mounting on a roof, or on the side of a building.
Installation shall not be attempted by someone who is not trained or experienced in this type of work.
The antenna has to be installed by a suitably trained professional installation technician. The site
prerequisites have to be checked by a person familiar with the national electrical code, and other
regulations governing this type of installation.
Outdoor antennas and antenna cables are electrical conductors. Transients or electrostatic
discharges that may occur at the antenna (for example a lightning strike during thunderstorms) may
damage your electronic equipment and cause personal injury or death to persons touching the
exposed metal connectors of the antenna cable.
When installing, disconnecting or replacing one of the cabling components, you must ensure at all
times that each exposed metal connectors of the antenna cabling system will be grounded locally
during the work.
Do not install this antenna where there is any possibility of contact with high-voltage arc-over from
power cables or service drops to buildings. The antenna, supporting mast or tower must not be close
to any power lines during installation, removal or in the event of part of the system should
accidentally fail. Apply a ‘Danger’ label to a plainly visible area of the antenna support structure.
Do not climb rooftops in wet or windy conditions, during a thunderstorm or when the area where the
equipment will be installed is covered with ice or snow.
Do not touch antennas, surge arrestors and antenna cables during a thunderstorm.
The location where you will install the antenna(s) must be at a safe distance from power lines or
telephone lines. The safe distance should be at least twice the height of the antenna mast plus the
height of the antenna.
Chapter 3. Installing the Antenna 26
CPN 65756 Issue Date: 01 August 2003
Tsunami MP.11a Antenna Installation Guide
Antennas shall be mounted in such a manner to minimize the potential for human contact during
normal operation. In order to avoid the possibility of exceeding the FCC radio frequency exposure
limits, human proximity to the antenna shall not be less than 2 meters (6 feet) during normal
operation.
The low-loss antenna cable that will connect the antenna with the surge arrestor must be at least 1 m
(3 ft) away from any high voltage or high current cable.
Check whether the antenna mast and its guy wires or wall bracket are positioned correctly and
secured properly to the roof or wall(s).
Check whether the grounding system for the antenna mast, the Tsunami MP.11a hardware and surge
arrestor have been installed. The grounding system must comply with the requirements as described
in “Grounding System.”
Always consult a qualified electrician if you are in doubt as to whether the antenna mast, the surge
arrestor and Tsunami MP.11a hardware are properly grounded.
The antenna cable between the antenna and the surge arrestor must be grounded at all times. If the
cable is disconnected at one end for some reason (for example, to replace the surge arrestor) then
you must ensure that the exposed metal connector of the cable is grounded locally during the work.
INSTALLATION OVERVIEW
The installation process can be summarized in the following steps:
1. Verify that the support structure for the antenna has been connected to the grounding system. If this is
not the case, you should do so now.
2. Connect the exposed metal connectors of the low-loss antenna cable to the grounding system.
3. Mount the antenna to the support structure, following the guidelines as described for your antenna.
4. Connect the antenna cable to the antenna.
5. Route the antenna cable to the surge arrestor that has been installed indoors.
6. Connect the antenna cable to the surge arrestor.
7. Attach the surge arrestor to the N-type male connector pigtail hanging from the cable opening in the
Tsunami MP.11.
8. Run the Link Test diagnostics of the management tools that come with the Tsunami MP.11a to aim the
antenna and verify optimal placement.
9. Once the antenna is correctly positioned, and you have verified the installation works properly, secure all
cables and use weatherproofing tape to seal all outdoor connectors.
Note: When you must remove or relocate the antenna, follow the Safety Precautions at the beginning of
this chapter and follow the steps listed above in exactly the reverse order.
Chapter 3. Installing the Antenna 27
CPN 65756 Issue Date: 01 August 2003
Tsunami MP.11a Antenna Installation Guide
MOUNTING THE ANTENNA
Proxim Corporation offers multiple antennas to set up a wireless link. As the mounting procedures for the
various antennas differ from one another, consult the documentation you received from the antenna
manufacturer for mounting procedures.
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 apart as you can.
▪ Alternate the mounting of directional antennas for vertical and horizontal polarization.
Connecting the Antenna Cable
Once the antenna is properly installed, you can connect the antenna to the Base Station or Subscriber Unit
by way of the surge arrestor:
1. Connect the antenna cable to the antenna.
2. Secure the antenna cable to the mast so that the cable connectors do not support the full weight of the
cable.
3. Connect the opposite end of the antenna cable to the surge arrestor.
CAUTION! To avoid damage to the antenna cable and connectors, refrain from using tools to
tighten the cable connectors.
4. Prior to securing the cable along its complete length, run the Link Test diagnostics of the management
tools that comes with Tsunami MP.11a to analyze wireless performance and optimal placement of the
outdoor antenna. How to use this tools is described in the documentation that comes with the Tsunami
MP.11a or can be from the Proxim website at http://www.expressresponse.com/proxim02/.
5. If required, adjust the direction of the antenna.
6. Once the installation has been fully tested, tighten the nuts of the antenna to “lock” the antenna into its
position.
CAUTION! Avoid over-tightening of the connector, and nuts and screws used to mount the
antenna, to prevent damage to your Tsunami MP.11a hardware.
7. Secure the cable along its complete length with cable ties or electrical tape to relieve strain on the
antenna connector properly. No part of the cable should be allowed to hang free. This is especially
important for those parts that are routed outside the building.
8. Proceed as described in the next section to weatherproof all outdoor coax connectors.
Chapter 3. Installing the Antenna 28
CPN 65756 Issue Date: 01 August 2003
Tsunami MP.11a Antenna Installation Guide
Sealing the Cable Connectors
Most problems associated with wireless outdoor installations are related to degrading performance due to
corrosion of the antenna cable and cable connectors. To avoid this type of problem, you must always seal
the cable connectors that are located outdoors using the weatherproofing tape provided.
You are advised to seal the connectors only after you have verified optimal alignment of the antennas using
the Link Test as described in the documentation that comes with the Tsunami MP.11. Doing so lets you
adjust antenna placement and cable routing without removing the tape.
1. Prepare the cable and connectors so that they are free from dust, dirt and grease.
2. Attach the tip of the weatherproofing tape to the cable just above the connector. Holding the tape in its
position, now stretch the tape and wind it half-overlapped around the cable and connectors to form a
void-free joint. The degree of stretch may vary in different sections of the joint, as long as the overlaps
accomplish a void-free application.
3. To protect the weatherproofing stretch tape from the effects of Ultra-Violet (UV) radiation (for example,
from direct sunlight), you should protect the joint with two half-overlapped layers of any vinyl plastic
electrical tape. Alternatively, you can apply silicone sealer to protect the weatherproofing tape from
sunlight, rain and other weather conditions.
Grounding System
Direct grounding of the antenna mast, Tsunami MP.11a hardware and surge arrestor is very important.
Note: A safety grounding system is necessary to protect your Tsunami MP.11a hardware from lightning
strikes and the build-up of static electricity.
WARNING! The antenna mast, Tsunami MP.11a hardware and surge arrestor must be connected to
the same ground, using an equi-potential bonding conductor.
A good electrical connection should be made to one or more ground rods, using at
least a 10AWG ground wire and non-corrosive hardware. The grounding system must
comply with the National Electrical Code and safety standards that apply in your
country. Always check with a qualified electrician if you are in doubt whether your
Tsunami MP.11a hardware installation is properly grounded or not.

Tsunami MP.11a Antenna Installation Guide
Antenna Alignment
For optimal performance of your wireless link, make sure the antennas are properly aligned (facing one
another “eye-to-eye”). To align the antennas:
▪ Use a pair of binoculars or a map of the area and a compass to point the antennas to one another.
▪ Use the Link Test option of the management tools that come with the Tsunami MP.11a to analyze the
radio link quality.
▪ The Link Test option lets you display the radio signal strength in relation to the noise in the signal path.
▪ If required, you can interactively optimize the antenna alignment with the Link Test, by making small
modifications in the antenna orientation.
▪ Alternatively, consult a professional Antenna Installation Service to optimize the antenna alignment.
Omni-directional antennas are characterized by a wide radiation pattern. Therefore, alignment of this type of
antennas is less critical than alignment of directional antennas.
Antenna Polarization
Tsunami outdoor antennas are standard mounted for vertical polarization.
In some cases, you might consider mounting the antenna for horizontal polarization. For example, to
minimize the influence of cross-talk between antennas when:
▪ You plan to mount multiple directional antennas to the same mast.
▪ Your wireless link receives interference from a vertically polarized neighboring installation.
Mounting for horizontal polarization is not supported for omni-directional grid antennas.
Note: For optimal wireless link performance, you must always verify that the antenna polarization on both
ends of the wireless link is the same. Consult the corresponding instruction appendixes for changing
the antenna polarization.
Antenna Cable Routing
The antenna cable must be routed and fixed in such a way that installation technicians have a clear passage
area. All connectors that are located outdoors must have a weatherproof seal. You are advised to seal
connectors only after you have completed the final radio tests.
BEFORE CLIMBING THE ROOF...
Before you start installing, check whether you have all the required components to set up an outdoor
wireless link. For each side of a wireless outdoor wireless link you need:
▪ One or two low-loss antenna cables
▪ A female-female converter N-connector in case you want to use two antenna cables
▪ Tools and material to mount the antenna
▪ Tape or wraps to attach the antenna cable, for example to the mast
▪ Grounding material such as cable and connector
If an item is missing or damaged during shipment, inform your supplier.

Tsunami MP.11a Antenna Installation Guide
Appendix A. Outdoor Antenna Equipment
As described previously, Proxim Corporation offers different types of outdoor antennas and cable lengths for
your network design.
The directional antennas provide maximum range, but due to their narrow beamwidth, these antennas
require precise antenna alignment to achieve optimal performance. The higher the antenna gain, the more
precise the alignment should be.
Directional antennas are typically used to connect:
▪ A Base Station Unit and a Subscriber Unit in a point-to-point link
▪ A Subscriber Unit in a point-to-multipoint network
The omni-directional antennas have, by nature, an omni-directional azimuth pattern that makes them easy to
install. There is also a gain beamwidth relation for omni-antennas: The higher the gain of the omni-antenna,
the narrower the vertical beamwidth. In a hilly terrain, a 7dBi omni-directional antenna can be a better
solution than the 10 dBi omni-directional antenna.
The 12 dBi wide-angle antenna is a good Base Station antenna for hilly terrain. It combines a wide opening
angle with relatively high gain. The mounting brackets allow tilting of the antenna. This antenna also is used
when the amount of traffic in a cell is too high for a single Base Station with an omni-directional antenna.
The wide-angle antenna allows dividing the cell into three sectors that each can be serviced by a Base
Station.
For beamwidth and gain characteristics of the various antennas, consult the appendixes of this manual,
which describe each antenna in more detail.
The length of the antenna cable also has an impact on the maximum range that can be achieved with the
antenna combination (see “Cable Factor” on page 17).
Depending upon local radio regulations in a number of countries that limit the maximum output power,
Proxim Corporation offers different outdoor antenna products in the various countries around the world.
Data Speed of the Wireless Link
By default, the radio of Tsunami MP.11a products transmits at the highest available transmit rate.
As data transmissions at lower speeds can travel larger distances than transmissions at the highest transmit
rate, the system lets you choose a lower data rate to increase the maximum range. For information about
customizing the transmit rate of your system, consult the Tsunami MP.11 and MP.11a Installation and
Management Guide (which is shipped with the Tsunami MP.11a).

DANGER!
Outdoor antennas and antenna cables are electrical conductors. Transients or electrostatic
discharges that may occur at the antenna (for example a lightning strike during thunderstorms) may
damage your electronic equipment and cause personal injury or death to persons touching the
exposed metal connectors of the antenna cable.
To avoid damage and personal injury, the entire antenna cabling system must be grounded at all
times.
When installing, disconnecting or replacing one of the cabling components, you must ensure at all
times that each exposed metal connectors of the antenna cabling system will be grounded locally
during the work.
For example when mounting or replacing the surge arrestor:
1. First connect each of the connectors of the low-loss antenna cables to the grounding system.
2. Next connect the cable connector to the grounding system.
3. Finally connect the surge arrestor to the grounding system.
Before you proceed, verify that each of the items is properly grounded and that the ground will not
interrupted when disconnecting one of the antenna system components.
Appendix B. Antenna Cabling System 34
CPN 65756 Issue Date: 01 August 2003
Tsunami MP.11a Antenna Installation Guide
Check with a qualified electrician if you are in doubt whether the surge arrestor and cable connectors are
properly grounded.
Only after you have verified that each of the items is properly grounded, replace the surge arrestor and
disconnect the cables from the grounding system in exactly the reverse order of the previous steps.
SURGE ARRESTOR
The surge arrestor (sometimes referred to as a Lightning Protector) can protect your sensitive outdoor router
equipment from high-voltage surges caused by discharges and transients at the antenna.
Figure 7. Surge Arrestor
To mount the surge arrestor:
1. Determine a suitable location for the bracket (item b) as described in “Chapter 1. Preparing for
Installation” on page 8.
2. Use the screws (item c) to attach the bracket to the wall.
3. Apply a ring-terminal to the ground wire. Use the bolt, lock-washer, and nut (item d) to connect the
ground wire (item e) to the mounting bracket.
4. The ring-terminal and ground wire are not included, but must be installed by a certified electrician familiar
with national electricity and safety codes, according to the instructions described in “Grounding System”
on page 16.
5. Insert the surge arrestor (item a) into the bracket as depicted in the preceding figure.
6. Use the hex-nut (item f) to secure the surge arrestor in its position. Ensure that the surge arrestor is
properly connected to the grounding system.

Appendix D. Certified Outdoor Solutions
INTRODUCTION
As radio regulations differ between the various countries world-wide, not all of the outdoor solutions
described in this Tsunami Outdoor Antenna Installation Guide may be allowed in the country where you plan
to install this equipment.
Local radio regulations or legislation may impose restrictions on the use of specific combinations of:
▪ Low-loss antenna cables and outdoor antennas.
▪ Radio channels selected at the Outdoor Routers that are connected to specific outdoor antennas.
Note: Basic rule for selecting a combination of cables and antennas is that no combination is allowed
unless explicitly approved in this Tsunami Outdoor Antenna Installation Guide. Therefore, always
use this Appendix in combination with “Chapter 2. Determining Range and Clearance” on page 16 of
this document to select the right type of antenna equipment and to inform your antenna installer and
LAN administrator about the impact of regulatory constraints on their job or activities.
SELECTING THE CORRECT CABLES
To comply with local radio regulations, the MP.11a Base Station and Subscriber units have a selectable
radio power output level. It can be selected through the TPC (Transmit Power Control) parameter in the user
Interface.
The low-loss antenna cables are available in various lengths and diameters:
▪ 6 m (15 ft) with a diameter of 5 mm (0.2 in) (The cable-loss of this cable is equal to the loss of the 15 m
(50 ft) cable.)
▪ 6 m (15 ft) with a diameter of 10 mm (0.4 in)
▪ 15 m (50 ft) with a diameter of 15 mm (0.6 in)
▪ 15 m (50 ft) with a diameter of 10 mm (0.4 in)
▪ 22 m (75 ft) with a diameter of 10 mm (0.4 in)
When you order the Tsunami MP.11a antenna equipment, make sure that you order cables that comply with
the regulations that apply in your country. (See Table 5 on page 24 for the minimum required antenna cable
attenuation and corresponding TPC setting.) In case of doubt, consult the Proxim Corporation Sales office
for more information.
