1.3.1 Important Safety Information
Antennas used for the purpose of radiating signals indoors are limited to a maximum gain of 10 dBi.
Each antenna must be positioned to observe minimum separation requirements from all users and
bystanders.
The following guidelines must be used when considering separation distances:
•
Indoor antennas must be placed so that under normal conditions, personnel cannot come
within 55 cm of any inside antenna. Adhering to this minimum separation will ensure that
the employee or bystander cannot exceed RF exposures beyond the maximum permissible
limit as defined by FCC Regulations section 1.1310 Limits for general
population/uncontrolled exposure.
•
Outdoor antenna must be positioned so that under normal conditions, personnel cannot
approach closer than 55 cm. A directional antenna having a maximum gain of 10 dBi is used,
and precautions should be taken to prevent personnel from routinely passing through the
main radiation beam at a distance closer than specified.

2 Product Overview
2.1 Product Information
The VHF Signal Booster was developed for use in enclosed structures where signals from local public
safety towers to operate mobile units is poor or unavailable. Adequate signal strength must be
available outside the structure as a prerequisite to achieving in-building coverage. The device is
connected to an external antenna, normally located on a roof, and to one or more internal antennas
placed strategically throughout the area where wireless service is desired.
The VHF Signal Booster Series is a Digital Signal Booster that operates in the 136 – 174 MHz frequency
range.
The external antenna is typically directional, such as a Yagi or Panel antenna. Internal antennas are
typically omnidirectional, although various other types may be used, depending on the coverage
application. The Signal Booster amplifies both the uplink (mobile to base) and downlink (base to
mobile) signals, thus facilitating communications to and from the intended wireless infrastructure.
With a maximum total of 80 dB nominal gain on both the uplink and downlink, gain can be adjusted
over a range from 52 dB to 80 dB in 1 dB steps.

5 Installation Guidelines
5.1 Important Installation Guidelines
• Westell Signal Boosters are designed for outdoor usage with a weather proof outdoor NEMA4 cabinet
that can be mounted without any kind of shelter from rain, snow or hail.
• The Signal Booster must be installed in a vertical orientation (i.e. Connectors on the bottom of the
unit).
• Inadequate isolation between the outside and inside antennas may cause regenerative feedback in
the system.
• This feedback can cause the amplifier to emit a continuous signal at maximum
Amplitude, and, in some cases, interfere with normal operation of the donor site.
Careful consideration of the layout and placement of the system is imperative to minimize this
possibility and to minimize the amount of signal leaking from the
Building.
• Do not disassemble the Signal Booster.
Danger!
• Refer to the 1.3 Safety Guidelines section for proper antenna selection and installation. To avoid
serious injury, death and/or damage to the Signal Booster, do not install donor or server antennas near
overhead power lines or high power components. Allow enough distance so that falling antennas
would not come in contact with those components.
• Electric shock may occur if the Signal Booster is installed in close proximity to water.
WARNING!
• Amplifier or handset damage may occur if a handset is connected directly to the Signal Booster or to
the coax that leads to the Signal Booster.
• The Signal Booster must be connected to ground for protection.
• We recommend that installers do not wear jewelry or metal accessories when installing this Signal
Booster.
• Do not place cables or tools that may damage the Signal Booster in close proximity to it.
• Check the installation site for hazardous conditions such as water-covered floors or badly worn or
damaged cables prior to installation.
• Lifespan and performance of the Signal Booster may be reduced if the unit is operating outside its
nominal temperature range.
• However, to improve reliability, it is recommended to mount the Signal Booster on a site with shelter
from direct exposure to sun, rain, snow and hailing.
• It is not recommended to install the Signal Booster under bad weather conditions, such as:
• Intense rainfall, snowfall or hail
• Storm or high wind
• Extremely low or high temperature
• High humidity of the air

5.2 Donor Antenna Installation Guidelines
• Accurately determine the azimuth to the donor site. Obtain the donor site information and approval from the
service provider/carrier.
• Ensure that the radiation path to the donor site is unobstructed.
• Mount the donor antenna at or toward the edge of the roof, in the direction of the donor site. Avoid having the
RF signal from the donor pass above the location(s) of the service antennas. Normally, the service antennas are
installed behind and below the donor antenna, as viewed from above. This approach helps avoid interference
and feedback to and from the service antennas.
• Normally, mounting the donor antenna higher will allow a less obstructed path to the donor site. However, in
high traffic metro areas, avoid mounting the donor antenna higher than necessary, as the quality of the donor
signal may become less stable and it is more likely to encounter adjacent channel interference.
• When possible, shield the rear of a donor antenna by locating it so that any HVAC units and/or penthouse
structures are behind the antenna, relative to the donor cell site location.
5.3 Indoor Antenna Installation Guidelines
• Use omnidirectional antennas (see section 2.4. Optional Accessories) indoors and locate them centrally with
respect to the intended coverage area to minimize signal leakage to the outside. Only use directional antennas
indoors in special cases when higher gain and directionality would be helpful and RF exposure limits will not be
exceeded.
• To avoid Signal Booster uplink overload and gain limiting, mount the indoor antennas away from areas where
mobile subscribers frequently use their phones / radios, such as desks or dispatch areas.
• To determine the quantity and locations of indoor antennas, measure Received Signal Strength Indication (RSSI)
using DM Tool software to determine areas of weak signals. These are the approximate areas where indoor
antennas may be needed.
• Be aware that the signal from an indoor antenna, in most cases, can be expected to penetrate approximately
two standard sheet rock walls to reach users. If the signal must travel through more than two walls, or if the
walls are made of materials other than sheet rock, it may be necessary to split the available signal and add more
antennas.

BE SURE THAT “TO MOBILE” AND “TO BASE” PORTS ARE PROPERLY LOADED
EITHER WITH 50 OHMS DUMMY LOADS, OR RADIATING SYSTEM.
The Digital Signal Booster may come in one out of two versions: a 32 narrow-band filters version or an
up-to-8 adjustable-bandwidth filters version. It is even possible to have both versions in one device so
that the user can choose either of them. Depending on which version is actually running, the main
screen of the Westell Control Software will have a slightly different look.
1. Turn on the Digital Signal Booster, connect computer to Signal Booster through Ethernet or USB cable,
and run Westell Control Software. It is recommend to turn off the power amplifiers.

4. Setup desired operating gain using FCS. UL and DL chain are independent, so both values must be set.
To set DL band gain is recommended that AGC works around 3dB in each channel, in this way, maximum
output power is achieved.
5. Set up squelch settings. Controls are independent in UL and DL bands. Typical values for UL are -
110dBm for squelch threshold. For DL, recommended value for squelch threshold is minimum level
received in any active channel minus 10dB.

6. For narrow band filters version, setup desired filter bandwidth, depending on presence of adjacent
channels. In principle, recommended bandwidth filter is 90KHz due to its low delay, but if adjacent signal
is detected, narrow filters can be used. Spectrum analyzer of FCS can be used to know rejection to
undesired signals. It is recommend that adjacent channels output power be, at least, 10dBc lower than
useful carrier.

8 Status Indicators
There is an indicator panel located at bottom of the Signal Boosters. This LED panel works as a
status monitor, in order indicate warning or alarms of Signal Booster.
The LED panel has four LEDs, the first one the power ON indication led, labelled “PWR”.
The Second LED, labelled “STS” summarizes warnings regarding critical operational conditions of
the Signal Booster.
The third and fourth LED summarizes operational conditions for uplink “UL” and downlink “DL”
chains.
In general, the LEDs have four states: “off”, “slow blinking”, “fast blinking” and “on”. Next table
describes alarm and warning conditions for each led state.
