Safety Precautions
7
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!
Outdoor antennas and antenna cables are electrical conductors. Transients or electrostatic discharges that may
occur at the antenna (such as 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 equipment if not
installed properly.
When installing, disconnecting, or replacing one of the cabling components, ensure at all times that each of the
exposed metal connectors of the antenna cabling system are 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 or removal, or in the event part of the system should accidentally fail. This includes the
installation process. 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 at which the
equipment is to be installed is covered with ice or snow.
Do not touch antennas, surge arrestors, or antenna cables during a thunderstorm.
Install antennas 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.
Mount antennas in such a manner as to minimize the potential for human contact during normal operation. To
avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antenna shall
not be less than 20 cm (8 inches) during normal operation.
Verify that the low-loss antenna cable that is to connect the antenna with the surge arrestor, or the Ethernet
cable that is to connect to the surge arrestor, is 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 walls. This should also include the confirmation that structure attachments are weatherproof.
Check whether the grounding system for the antenna mast, the Tsunami MP.16 equipment hardware, and the
surge arrestor have been installed. The grounding system must comply with the requirements as described in
Grounding the Antenna and local electrical code requirements.
Always consult a qualified electrician if you are in doubt as to whether the antenna mast, the surge arrestor, and
the 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), you must ensure that the
exposed metal connector of the cable is grounded locally during the work.

Installation Process Overview
The installation process can be summarized in the following steps:
1. Verify that the support structure for the antenna and radio has been connected to the grounding system. If this is not
the case, connect it properly.
2. Mount the antenna to the support structure, following the guidelines as described for your antenna’s documentation.
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 possible.
– Alternate the mounting of directional antennas for vertical and horizontal polarization.
3. Connect the antenna cable to the antenna.
4. Route the antenna cable to the surge arrestor that has been installed near the ingress point.
5. Connect the antenna/Ethernet cable to the surge arrestor.
6. Attach the surge arrestor to the N-type female bulkhead connector.
7. Run the Link Test diagnostics of the management tools that come with the radio unit to aim the antenna and verify
optimal placement.
NOTE: You can also use the unit’s Antenna Alignment utilities. See Aligning the Antenna.
8. 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 Installation Precautions and Safety Precautions
given in this guide, and follow the steps listed above in exactly the reverse order.

Indoor-Mounted Radio Hardware and Cable Overview
Indoor Radio Hardware
Model 5054, 5012-SUI, and 5054-SUI radios are intended for indoor mounting and operation. For these indoor radios, the
antenna cable is connected to the connector pigtail extending from the radio.
The following types of radio devices are used for setting up a wireless link with the 5054, 5012-SUI, and 5054-SUI:
• Tsunami MP.11 5054 (MP.11a) Base Station Unit (BSU)
• Tsunami MP.11 5054 (MP.11a) Subscriber Unit (SU)
• Tsunami MP.11 5054 (MP.11a) Residential Subscriber Unit (RSU)
• Tsunami MP.11 5012-SUI Subscriber Unit (SU)
• Tsunami MP.11 5054-SUI Subscriber Unit (SU)
Indoor Radio Cable Setup for an External Antenna
The following items are required on each end of the wireless link:
• A Base Station on one end and a Subscriber Unit on the other end.
• A surge arrestor to protect your sensitive equipment from static discharge and transients (optional, but highly
recommended).
• N-type female-female converter connector (optional, needed only if a surge arrestor is not used, or if an additional
antenna cable is required when a surge arrestor is used, see next bullet).
• A low-loss antenna cable to connect the indoor radio unit to the surge arrestor (optional, only if the radio unit is not
mounted close to where the cable coming from the antenna enters the building, which is the place where the surge
arrestor must be mounted).
• A low-loss antenna cable to connect the surge arrestor to the outdoor antenna (if surge arrestor is used), or the unit to
the antenna (if surge arrestor is not used).
• External antennas (one at each end).
• A grounding system, as described in Grounding the Antenna.
When the unit is not mounted close to where the antenna cable enters the building (where the surge arrestor must be
mounted), an additional cable between the unit and the surge arrestor is required, plus a female-female converter
connector. If the unit is mounted close to the surge arrestor, the unit can be connected directly to the surge arrestor.
Proxim strongly recommends to use a surge arrestor to protect your sensitive equipment from static discharge and
transients. An exception to this rule is when the antenna is installed in an indoor location. This installation does not
require the use of a surge arrestor. The antenna can be connected directly to the radio unit via a cable and a
female-female converter connector.
All cabling components of the antenna system come with standard-N type connectors. Note that the gender of the
connector is not determined by the connector’s thread, but by its center pin. A solid center pin = male; a hollow center pin
= female.
The following sections describe all the possible combinations of cabling components. The 5012-SUI/5054-SUI is
pictured.

Indoor Radio Cabling Precautions
Note that prior to mounting the radio unit, you are advised to carefully calculate:
• The distance between the intended location of your unit and the location of the antenna mast
• The height of the antenna on the mast
If the low-loss antenna cable for the unit is not long enough to cover this distance, you either can select another cable
length from the Proxim’s low-loss cable offering, or select another location that satisfies the requirements previously
listed to mount your unit. The radio unit can be placed anywhere, as long as Ethernet cable length allows. Because the
length of the antenna cable can affect the actual range of your outdoor antenna installation, Proxim recommends
selecting another location or using a different radio model.
WARNING: You must not change the length of the low-loss antenna cable used with the radio unit to a length
shorter than allowed by the radio’s certifications. Shortening the cable voids the Proxim Wireless
Corporation warranty and can conflict with radio certifications or approvals.
CAUTION: The radio hardware, the surge arrestor, and the antenna mast must be connected to the same grounding
system.

Outdoor-Mounted Radio Hardware and Cable Overview
Outdoor Radio Hardware
The MP.11 954-R, 2454-R, 5054-R, 5054-R-LR, and 4954-R Base Station Units and Subscriber Units are intended for
outdoor mounting and operation. Outdoor units are referred to collectively as MP.11-R units.
To make optimal use of the units, you must find a suitable location for the hardware. The radio range largely depends
upon the position of the antenna. Because of this Proxim recommends you do a site survey.
The following three types of radio devices are used for setting up a wireless link:
• Tsunami MP.11-R Base Station Unit (BSU) with external antenna connector
• Tsunami MP.11-R Subscriber Unit (SU) with external antenna connector
• Tsunami MP.11-R Subscriber Unit (SU) with integrated antenna for outdoor use
Outdoor Radio Cable Setup for External Antenna
The following items are required on each end of the wireless link:
• A Base Station or a Subscriber Station
• A low-loss antenna cable to connect the radio unit to the external antenna (for units using an external antenna
connector only).
NOTE: Proxim recommends an LMR-600 cable (2 meters), available from Proxim Wireless Corporation.
• A surge arrestor for the CAT5 Ethernet cable that connects the power supply to the radio.
• Outdoor antenna (for use with units equipped with an external connector only).
• A grounding system, as described in Grounding the Antenna.
When the BSU and SU are equipped with external antenna connectors, the radios are connected through the RF cable to
an external antenna. The recommended RF cable length is two meters. This is not needed for the SU with the integrated
antenna. The Ethernet cable is connected from the radio to the Ethernet surge arrestor. The surge arrestor is located on
the outside of the building (with proper grounding) very near to the point where the cables enter the building. An outdoor
rated CAT5 Ethernet cable should be used.
CAUTION: The Tsunami MP.11-R hardware, the surge arrestor, and the antenna mast must be connected to the same
grounding system as prescribed by local electrical codes.
The following is an overview of the cable setup for the outdoor antenna.

The power injector is designed for indoor mounting and operation. In addition to supplying power to the radio unit there is
a data output connection on the power supply. 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.
• The location must allow for easy disconnection of the power supply from the AC wall outlet.
• The location provides a connection to the network backbone through an Ethernet CAT5 cable that is connected to a
hub, bridge, or directly into a patch panel or to a computer through a null modem cable.
• The ideal location has a temperature of 0–55º C and a maximum relative humidity (non-condensing) of 95%.

Surge Arrestor
The surge arrestor is an indispensable part of your outdoor radio installation. It protects your sensitive electronic
equipment from transients or electrostatic discharges at the antenna.
For optimal protection, the surge arrestor must be installed at a location that is very near to where the CAT5 Ethernet
cable enters inside the structure. This location should allow proper grounding complying with local electrical code
requirements.
Ethernet Cable
The antenna cable must be connected from the antenna through the surge arrestor to the antenna connector of the unit.
To plan the route of the antenna cable for an indoor unit (5054), 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 such as 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) and 15 mm (0.6 in) diameter.
CAUTION:
•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.
•The antenna cable and cable connectors are not designed to withstand excessive force:
–Do not use the connectors as ‘cable grips’ to pull 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 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, verify whether the installation and all components functions properly.

Required Materials
The outdoor installation of the link requires the following:
• An antenna or unit with an integrated antenna
• A low-loss antenna cable (for units with external antennas only)
NOTE: Proxim recommends an LMR-600 cable (2 meters), available from Proxim Wireless Corporation.
• Antenna mast or wall bracket for the antenna/unit
• A grounding system that meets the local electrical code requirements
• Waterproofing of all connections (see Sealing the Cable Connectors)
DANGER!
For your own safety, the antenna mast and the grounding system should be installed only by experienced
installation professionals who are familiar with local building, safety, and electrical codes in the country of use.

IMPORTANT!
Before climbing the roof to begin installation, check whether you have all the required components to set up an
outdoor wireless link. For each side of the link, you will need:
• Radio unit with integrated antenna; OR radio unit with external antenna connector, external antenna, and
antenna-to-radio connection cable(s)
• Tools and material to mount the antenna
• Tape or wraps to attach the antenna cable, for example, to the mast
• Ethernet cable with waterproof cap
• Proper tools to allow system installation
• Radio, antenna, and antenna support grounding material that meets local electrical requirements

Determining Optimal 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 unit. Although the radio signal can work well without line-of-sight in urban environments in which the
signal is transported by reflection rather than being direct, the best results are achieved in line-of-sight conditions.
Line-of-sight is 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
contains a bulged area known as Fresnel Zone.
The 1st Fresnel zone is an imaginary boundary line offset along the direct signal path. This boundary is defined as the
point where, if a signal were reflected between the two antennas, it would travel a distance exactly one-half wavelength
longer than the direct-path signal. Each succeeding Fresnel zone boundary adds an additional half-wavelength to the
reflected path distance between the antennas.
Signals reflected from any even-numbered Fresnel zone result in signal cancellation; those from odd-numbered Fresnel
zones add to the direct path signal.
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 6.8 m in the middle of the wireless link for a distance of
6 Km and a frequency of 3.5 GHz. This width is also the required clearance of the antenna beam from obstacles in its
path, to avoid loss of radio signal.
When any significant part of this zone is obstructed, a portion of the radio energy is 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.
For 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. See
Determining the Outdoor Range.
The following figure shows some typical examples of obstacles you must avoid for the directional antenna to operate
effectively:
a. Neighboring buildings
b. Trees or other obstructions
c. Power lines

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:
– 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 in which large reflecting
surfaces exist in parallel or partly perpendicular to the antenna beam.
Environments with large reflective surfaces include:
• Mirror-glass buildings
• Crowded parking lots
• Water surface 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 Proxim 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
when leaves are present.
• In winter, a wireless link can 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.
