Preparing to Install zBoost®
Overview
ank you for choosing zBoost®. You will now be able to use cell phones INSIDE the building. Gone are
the days when one had to go to the window upstairs or walk outside to use a cell phone. Like a skylight that
brings sunlight into a home, zBoost® transports and amplies the outdoor cellular signals into the building.
By following the easy instructions in this user guide, you will be Extending Cell Zones™ into the building.
Why Indoor Signals Can Be Weak
ere are several obstacles that can contribute to the poor reception you receive in a building:
1. Location of the Cell Phone Tower in Relation to the building
While cell phone providers have tried to place cell phone towers to provide the best overall coverage,
local ordinances and terrain features can impose restrictions on where these towers can be placed,
thus, limiting the signal strength available at your location.
2. Obstructions Caused by Buildings, Terrain and Trees
Cell phone signals can be completely blocked or reected by buildings, walls, trees, hills and other
terrain features resulting in low signal strength.
3. Energy Efficient Windows
ese new windows can also aect signal penetration into the house
Tools Needed
e following tools are needed to set up zBoost®:
• #2 Philips screwdriver
• Cellular phone operating in the band supported by your zBoost® unit
• Drill (may be required for outdoor or attic antenna placement)
Check for Signal Strength
Before placing a zBoost® in a home, make sure that you can place calls on the outside of the building, in the
attic, at roof level or wherever you plan to place the Signal Antenna. zBoost® can only bring signal into the
building when signal reaches the Signal Antenna. If there is no signal, the zBoost® will not work for you.
Using your cell phone, place a call from an outdoor location to conrm that enough signal is present to
complete the call. If a weak signal is available at ground level, check the signal strength in the attic or at roof
level location where the signal will likely be stronger and where the Signal Antenna can be placed for best
performance.
If you can reliably make and receive calls outside the building, then zBoost® can bring the signal into your
home.
If only one signal bar is displayed on your cell phone outside, indoor coverage will be limited to one to
two rooms. We recommend placing the Signal Antenna outside and/or purchasing a Wi-Ex® upgrade Signal
Antenna for increased coverage (see page iv).
e YX699 Signal Meter (available separately) provides signal strength information. It can be used with
its supplied whip antenna to nd the best location for placement of the Signal Antennas by identifying the
area of strongest signal. It can also be used to identify peak antenna alignment when connected directly via
provided cable. Contact Wi-Ex to obtain a YX699 Signal Meter.
Read First Before Installing the YX645
Before unpacking this box, verify that your phone operates on the frequency band supported by this product.
Note: The YX645 is not compatible with iDEN, Nextel, SMR or ESMR frequency services.
Cell phone signal bars are approximate and vary from
phone to phone. e number of bars can uctuate widely,
depending on the location of the phone, the position or angle
of the phone, weather, etc. Most cell phone signal meters
update every 6 to 10 seconds. An increase of only one bar
typically indicates a 4x to 10x signal increase
THE BEST INDICATOR OF COVERAGE AREA IS THE
ABILITY TO RELIABLY PLACE AND RECEIVE CALLS
Note

Determine the Needed Coverage Area
Identify the location in your home/oce where you need signal coverage the most. e zBoost® YX645
can cover up to 10,000 square feet (coverage varies based on outdoor signal level, building construction,
placement of antennas, and general installation care). Walls, ceilings or oors will reduce the coverage area.
Determine the Location of Signal Antennas and the Indoor Antenna
It is recommended that the Signal Antennas and Indoor Antenna have over 15 feet
of vertical and 20 feet of horizontal separation.
If the antennas are too close together, the light on the Base Unit will ash red, indicating a problem see the
Light Indicators section (Page 12). To capture the best signal, place the Signal Antenna as high as possible
and position it vertically, keeping it at it at least 2 feet away from any metal.
Place the Signal Antennas as high as possible to capture the best signal.
See page 6, Installing Your zBoost® Product, for additional information.
Note: Coverage and Signal Antennas should be pointed AWAY from each other.
Cable Requirements
You must use RG-6 coaxial cable and F connectors which are rated for outdoor satellite TV use and can be
found at many home improvement and electronic stores.
Coaxial cable is not provided with the YX645. After installing the Signal Antennas, run coaxial cable
between antenna assembly and Base Unit. e recommended maximum cable length run for RG-6 is 60’
and 100’ for RG-11. It is highly recommended that you refrain from securing your cable, drilling any holes,
etc. until you complete and test the installation of the Base Unit..
Caution: Before drilling any holes into a wall to run your cable, make sure you know where existing
electrical wiring is located. Drilling into live electrical wiring could cause and electrical shock and sever the
wire.
Grounding the Directional Signal Antennas
e Directional Signal Antenna assembly must be properly grounded when it is installed outdoors. is will
help protect the customer’s property and the Base Unit against lightning strikes during a lightning storm.
e installation must be in accordance with Article 810 of the National Electric Code (NEC). A listed
antenna discharge unit must be provided for the lead-in coaxial cable per NEC article 8.10.20 or the shield
of the coaxial cable must be permanently and eectively grounded in accordance with NEC article 8.10.21..
Securing Cable with a Drip Loop
When you install the Directional Signal Antennas,
create a drip loop with the coaxial cable at the point
where the cable enters the building through an outside
wall. is can be done by twisting and securing the
cable into a loop (no less than 4” across) near the entry
point. is will help prevent moisture from gathering at
entry point and leaking into the building.
Important Reminders:
• e required coaxial cable has NOT been provoided.
• An exterior mounting mast has not been provided. Using at least 1.5” PVC pipe or a J-pole (available
from Wi-Ex, part YX014) is suggested should one be needed..
Power Requirements
e Base Unit can be plugged into a standard 2-prong 110 VAC receptacle using the included power supply.
e power supply consumes less than 10W (less than 0.2A).
Coax Cable
Exterior Wall
e zBoost® YX645 base unit MUST only be used with the
provided power adaptor. Use of other power adaptors will
void the warranty and may damage the unit. Use of other
equipment is not FCC approved.
Note
Avoid placing the Signal Antenna near metal such as
wiring, A/C ducts, metal siding, truss plates, etc.
When connecting the cable to the antenna, run the cable
straight down from the antenna. Avoid draping the coax
near the antenna.

Installing Your zBoost® Signal Booster
Placement of the Signal Antennas
Choosing the best location for installation of the Signal Antenna provides the best performance and the
largest area of improved signal. Determine the location which provides the strongest signal using the signal
strength indicator on your cell phone. Find the location which provides the most bars of signal strength and
locate the Signal Antenna at that location. is location will be typically found on the roof.
e YX699 Signal Meter (available separately) provides signal strength information. It can be used with its
supplied whip antenna to identify the area of strongest signal for placement of the Signal Antennas. It can
also be connected directly to the Signal Antennas to identify peak antenna alignment. Contact Wi-Ex to
obtain a YX699 Signal Meter.
Mounting Signal Antennas
1. When you have determined the location of the strongest signal, install the antennas to a mast or
j-pole (Not provided- OutdoorJ-pole Antenna Mounting Bracket, YX014). Loosely tighten the
antennas to the mast to allow the antennas to be reoriented for strongest signal.
2. Connect the provided coax from the panel antenna to the connection on the Signal Combiner
marked CEL. Connect the supplied 18” coaxial jumper from the Panel antenna to the other Signal
Combiner port marked PCS.
After installing the Signal Antennas to a mast or pole, connect them to the Signal Combiner (as pictured
below). Make sure to connect PCS and CEL outputs to the matching antenna. Connecting the antenna to
the wrong Signal Combiner port will not produce an improved signal. en, connect either RG6 or RG11
(not included) coax cable to the opposite end of the Signal
Combiner going to the Base Unit.
Avoid placing the Signal Antenna near metal such as
wiring, A/C ducts, metal siding, truss plates, etc.
When connecting the cable to the antenna, run the cable
straight down from the antenna. Avoid draping the coax
near the antenna.
Note Outdoor Signal Antenna
Signal Combiner
NOTE: e zBoost® YX645 requires at least 15 feet of vertical separation between the Base Unit and the
Signal Antennas. Generally, increasing this distance (up to 40 feet) will increase the performance and decreasing
the distance will limit zBoost® performance. (If 15 feet of separation is not possible, you may try our new
METRO model, which was designed for lofts and urban dwellings and requires no vertical separation.) Keep the
Base Unit o the oor and at least 2 feet away from other cords, metal objects or other wireless devices such as
wireless routers or wireless access points. e zBoost® performs best when there are no obstructions between the
zBoost® Base Unit and your mobile device.
Upon initial power up, a solid GREEN light should appear indicating normal conditions. If a RED light
appears, adjustments may be needed to optimize performance. If you nd the increased signal coverage is
acceptable, however, no additional adjustments are needed. See Light Indicator section (Page 12) for more
information.
Antenna Aiming
To get the maximum benet, , you will want to take special care to make sure you point the antennas in the
direction of the best signal for your wireless service provider. You may wish to use a YX699 RF signal meter
to help during this process.
Note: The Outdoor Signal Antenna must be pointed AWAY from the Indoor Antenna. Additionally, it
should be mounted of the roof edge, pointed away from the building.
If you do not know which direction the best signal is coming from, once the unit is installed, rotate the
Signal Antennas in 90 degree increments while measuring the results inside the desired coverage area. In
most cases both Signal Antennas should be aimed in the same direction.
1. Using a phone operating in the Cellular band, place the cell phone on a non-metal surface about 6-8
feet from the Base Unit.
2. Turn the signal booster on and wait 30 seconds. Note the number of signal bars displayed on
your cell phone. For best results, you want to place your phone where the phone’s signal meter
displays in the middle of the signal meter range or less so that it can indicate as you rotate the
Signal Antenna to the optimum direction. If it is reading too high, move the phone farther from the
Indoor Antenna.
3. Record the number of signal bars or dBm________(A) on your cell phone. You can use our YX699
RF Signal Meter or an application on a smart phone to get the dBm. Leave the phone in exactly the
same place and pointing in the same direction for the following steps. Note the direction of the
CEL Panel Signal Antenna starting position ________________.
4. Rotate the CEL Panel Signal Antenna 90 degrees and then record the phone signal bars _________
(B).
5. Continue to rotate the antenna another 90 degrees in the same direction and record the phone
signal bars _________(C).
6. Again, rotate the antenna another 90 degrees in the same direction and again record the phone
signal bars _________(D).
7. If you desire to optimize further, then look for the two highest signal bar readings above and move
the antenna between these two points to nd the highest signal bars reading.
8. Look for the highest reading above. Set the antenna to that position and tighten the antenna to
the mast of your choosing. We suggest PVC pipe that is at least 1.5” or J-Pole (part # YX014, not
included).
9. Using a phone operating in the Cellular band, place the cell phone on a non-metal surface about 6-8
feet from the Base Unit.
10. Turn the signal booster on and wait 30 seconds. Note the number of signal bars displayed on your
cell phone. For best results, you want to place your phone where the phone’s signal meter displays in
the middle of the signal meter range or less so that it can indicate as you rotate the Signal Antenna
to the optimum direction. If it is reading too high, you may want to move the phone farther from
the Indoor Antenna so that you are able to see the change when you reorient the Signal Antenna.

Installing the Indoor Antenna
e interior panel antenna is connected to the base unit using the provided 10’ RG-8X coax. It should be
mounted on a wall facing the direction where increased coverage is desired..
Before drilling any holes into a wall to run your cable,
make sure you know where existing electrical wiring is
located. Drilling into live electrical wiring could cause an
electrical shock and sever the wire.
Note
11. Record the number of signal bars ________(A) on your cell phone. Leave the phone in exactly the
same place and pointing in the same direction for the following steps. Note the direction of the
Panel antenna starting position ________________.
12. Rotate the Panel antenna mast 90 degrees and then record the phone signal bars _________(B).
13. Continue to rotate the antenna mast another 90 degrees in the same direction and record the phone
signal bars _________(C).
14. Again, rotate the antenna mast another 90 degrees in the same direction and again record the phone
signal bars _________(D).
15. If you desire to optimize further, then look for the two highest signal bar readings above and move
the antenna between these two points to nd the highest signal bars reading.
16. Look for the highest reading above. Set the antenna to that position and tighten the antenna to the
mast.
e majority of the time a cell tower will hold more than 1 frequecy band and/or service provider, so aim the
second Signal Antenna in the same direction. You may need to use a PCS phone.
To aim each antenna for maximum signal, you may need more than one cell phone, one operating in the
Cellular band (typically AT&T, Verizon or Alltel) and one operating in the PCS band (typically Sprint,
T-Mobile, Metro PCS, Cricket).
Note: A 1 dBm increase is 25% gain in signal strength.
Running the Coaxial Cable to the Base Unit
Coaxial cable is not provided with the YX645. After installing the Signal Antennas and connecting them
you will need to run coaxial cable to the location where you plan to install the Base Unit. e recommended
maximum cable length run for RG-6 is 60’ and 100’ for RG-11. It is highly recommended that you refrain
from securing your cable, drilling any holes, etc. until you complete and test the installation of the Base
Unit.
For example, if you plan to use the Base Unit in the living room of a two-story home, rst run the cable
from the attic down the stairs to the living room. After the Base Unit is installed and successfully working,
nd a more direct and permanent route for the cable (e.g., dropping it through the ceiling of a nearby
closet).
Wall Mounting the Base Unit
e Base Unit can also be easily mounted on a wall. e Base Unit should be a minimum distance of 4-5
feet o from the oor so there is clearance for the Indoor Antenna extension.
Perform the following steps to mount the Base Unit on a wall:
1. Remove the mounting bracket from the Base Unit by slightly spreading the tabs on the orange
mounting bracket.
2. Fasten the mounting bracket to the wall using the self-tapping wall/ceiling anchors.
3. Snap the Base Unit into the mounting bracket.

Conrm at Your zBoost® is Working Properly
Perform the following steps to conrm that the unit is now working properly:
1. Unplug the Base Unit power cord.
2. Turn on your cell phone and check the signal meter.
3. Plug the power cord into the Base Unit.
4. Hold your cell phone about 5 feet from the Base Unit and then turn it on. Wait up to 1 minute for
the cell phone to register the signal coming from the Base Unit.
5. If the signal meter shows an improvement, your zBoost unit is working properly.
Improving Your Coverage Area
With everything connected and the Base Unit plugged in, you should walk throughout the room and see
that you are able to reliably place calls.
Remember, coverage varies based on outdoor signal level, building construction, and general installation
care. Coverage in adjoining rooms (next to, above, or below) will be reduced due to the walls or the ceiling/
oor.
Should you desire to improve coverage, you may:
1.) Move the Base Unit and/or adjust the angle of the Indoor Antenna.
2.) Move the Signal Antenna to a higher location in the attic or outside.
3.) Purchase a Signal Antenna upgrade at www.Wi-Ex.com.
Note: Using a signal meter or an antenna application on a smart phone is a more accurate way to measure a
stronger signal than the bars on a phone.
Upon initial power up, a solid GREEN LED should appear indicating normal conditions. If a RED light
appears, adjustments may be needed to optimize performance. If you nd the increased signal coverage is
acceptable, however, no additional adjustments are needed. See Light Indicator section for more information

Frequently Asked Questions
What can I expect my cell phone signal range and strength to be inside my home or office?
e closer you are to the base, the stronger the signal. is will vary with dierent conditions. Some of the
conditions that will aect the improved coverage area are signal strength outdoors, the type of building
materials in the home, the placement of the unit and the antenna’s proximity to cellular towers.
You can expect that your indoor coverage will be improved. You will be able to make calls where you couldn’t
before. e degree of improvement will depend upon many factors. e intent of zBoost® products are to
bring outside coverage inside. Just as the signal bars move up and down when outside, the boosted signal
will uctuate in a similar fashion.
Is a cellular phone signal booster the same as a wireless router; will it help my WiFi signal?
e Wi-Ex® unit will not help your WiFi service. is unit is designed to work with wireless PCS and
Cellular phones and devices. e WIFI in your home or oce operates on a dierent frequency.
Is your product available for international use?
Yes, we have products that work on European frequencies. Our zBoost® YX520-I– Dual band works on
900MHz and 1800Mhz.
We also sell zBoost® ONE YX400-U for UMTS/HSPA devices on the 2100MHz Frequency, a frequency
used for voice and data overseas.
Why isn’t my cell phone indicating more signal with more bars?
You may not always observe more bars that gain on your signal meter because of the signal spreading out
from the antenna. If your phone has a dB meter, 3dB is a signicant increase of 2x, 6dB is 4x, and 10dB is
10x. On a four bar phone, one "bar" equals about 10dB.
e increase in signal you will see depends upon:
• e level of signal at the Signal antenna (outdoor)
• e care of the antenna placement (two feet away from metal, adequate antenna separation [15 feet
recommended])
• e signal already present inside (related to building losses)
• e distance of your phone/device from the Base Unit (signal spreads or diminishes rapidly with dis-
tance.)
There are usually several cell phones in use at one time in my home, will your product boost all of our
signals simultaneously?
e zBoost® YX645 is designed to cover multiple signals simultaneously and will allow multiple users to
operate at the same time.
Does the zBoost® work if you have no bars?
No, if no signal is present outdoors zBoost® producs will not work for you. Also, keep in mind if your best
signal is 1 bar at the Signal Antenna, your coverage will be limited to one or two rooms. You could improve
that with an upgraded antenna. (See page iv).
Frequently Asked Questions
Where should I put my Wi-Ex base unit to get the best coverage?
You should install your base unit where you need coverage the most. e Wi-Ex base unit is the component
that amplies the signal inside. e coverage is improved in a circular manner from the base unit. e
farther you are away from the base unit, the weaker the signal. e base could be placed in the family room,
the basement, an oce, a bedroom, a home oce or a central location.
Note: if you install the Signal Antenna too close to the Base Unit, the system will shut down (red light will
blink). is is a normal condition for this scenario. It just means that you need to ensure that you have
sucient distance between the 2 antennas; otherwise, it will detect feedback or noise and will automatically
shut down.
Where is the best place to put my Wi-Ex Signal Antenna?
e Wi-Ex signal antenna should be placed at the highest point in your house in order to “catch” the
strongest signal. is location could be in the attic or on the roof. e placement of the Signal Antenna is
very important. It is best to place this in an un-obstructed area. If you install it outside, place it above the
roof line. Or, this antenna can be placed in the area around your home that has the greatest signal strength.
Note: if you install the Signal Antenna too close to the Base Unit, the system will shut down (red light will
appear). is is a normal condition for this scenario. It just means that you need to ensure that you have
proper isolation between the 2 antennas; otherwise, it will detect feedback or noise and will automatically
shut down.
My light is continually blinking
ere are several reason that the zBoost® light could be blinking. Please see the Light Indicator section on
Page 12 for specic answers.
Does the zBoost® work on all 3G data?
No, it only works on data that is on 1900 and 800 mHz frequency like iPhones, but not on smartphones
that use 3G on 2100 mHz frequencies.
