Overview
Thank you for choosing zBoost! You will now be able to use your cell phone INSIDE your home.
Gone are the days when you had to go to the window upstairs or walk outside to use your cell
phone. Like a skylight that brings sunlight into your home, zBoost transports and amplies the
outdoor signal into your home.
By following the easy instructions in this User Manual, you will be Extending Cell Zones™ into your
home.
Why Indoor Signals Can Be Weak
There are several obstacles that can contribute to the poor reception you receive in your home:
1. Location of the Cell Phone Tower in Relation to Your Home
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 Efcient Windows
Energy efcient windows contain a metal lm that can affect signal penetration into the
house.

zBoost®PRO 7500 ZBC745SL-CM Manual

Preparing to Set Up Your zBoost Product
Tools Needed
The following tools are needed to set up zBoost:
• #2 Phillips 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 your home, make sure that you can place calls on the outside of your
home, in the attic, at roof level or wherever you plan to place the External Antenna. zBoost can only
bring signal into your home when signal reaches the External 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 your
attic or at roof level location where the signal will likely be stronger and where the External Antenna
can be placed for best performance.
If you can reliably make and receive calls outside your home, 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
reduced from the rated 7,500 sq. feet.
Note
Cell phone signal bars are approximate and vary from
phone to phone. The 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.

zBoost®PRO 7500 ZBC745SL-CM Manual

Coax Cable
Exterior Wall
Before installing, please note the following important factors in determining your zBoost
performance:
• At least 15 vertical feet is needed between the External Antenna (receives the outside signal)
and the Indoor Antenna (rebroadcasts the signal indoors). Separation less than 15 vertical
feet will result in decreased performance. See illustration below.
• Keep the External Antenna at least 3 feet above any metal.
See “Installing Your zBoost Signal Booster” on page 5, for additional information.
Cable Requirements
RG-6 cable is used to connect the External Antenna and the Base Unit. Should you need additional
cable length, 15 foot extensions (Part #: YX030-15w) are available at www.zBoost.com.
The total cable length should not exceed 65 feet unless you also purchase an upgraded External
Antenna or upgrade the cable to RG-11. (see page v). The recommended maximum length
for RG-11 is 120 ft. A longer cable is helpful only if it allows you to place the External Antenna in
a location where you measure stronger signal. It is highly recommended that you refrain from
securing your cable, drilling any holes, etc. until you complete and test the installation of the
system.
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 External Antennas
If you decide to place the External Antenna outdoors, it must be properly grounded. (See page
v for a recommended grounding kit).
The set up 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 effectively grounded in accordance with
NEC article 8.10.21. Please consult a professional installer
or electrician for more information.
Securing Cable with a Drip Loop
When you install the Directional External Antennas, create
a drip loop with the coaxial cable at the point where the
cable enters the home through an outside wall. This can be
done by twisting and securing the cable into a loop (no less
than 4” across) near the entry point. This will help prevent
moisture from gathering at entry point and leaking into the
home.

Power Requirements
The Base Unit can be plugged into a standard 2-prong 110 VAC receptacle using the included
power supply. The power supply consumes less than 10W (less than 0.2A).
Important Reminders:
An exterior mounting mast has not been provided. Using at least 1.5” PVC pipe or a J-pole
(available from zBoost, part YX014) is suggested should one be needed.
Installing Your zBoost Signal Booster
Outdoor External Antenna
FIRST: Placement of the External Antenna
Choosing the best location for the External Antenna provides the best performance and the largest
area of improved signal. Choose a location for the External Antenna using your cell phone to
determine the area of strongest signal - typically found outside, above the rooine or in an attic. The
antenna must also remain at least 3 feet from any metal objects such as pipes, metal siding, A/C
unit etc. and at least 15 vertical feet above the Indoor Antenna.
The YX699 Signal Meter (available separately) provides signal strength information. It can be used
with its supplied whip antenna to nd the best location for antenna mounting with the strongest
received signal. It can also be connected to the directional antenna to aim the antenna for
maximum received signal. Contact zBoost to obtain a YX699 Signal Meter.
Mounting of Antenna
1. When you have determined the location of the strongest signal, install the antenna to a
mast (not provided). Outdoor J-pole Antenna Mounting Bracket, YX014 is available at
www.zBoost.com. Loosely connect the antenna to the mast to allow the antenna to be
reoriented for strongest signal. Take special care in aiming the External Antenna in the
direction of best signal. If you are unsure of the nearest tower location of your wireless
provider, see”Antenna Aiming” on page 7 for detailed instructions.
2. After installing the External Antenna to a mast or pole, connect RG-6 coax cable to the
External Antenna and run to the Base Unit.

zBoost®PRO 7500 ZBC745SL-CM Manual

NOTE: The zBoost PRO 7500 ZBC745SL-CM requires at least 15 feet of vertical separation
between the Base Unit and the External Antenna. Generally, increasing this distance (up to 40 feet)
will increase the performance and decreasing the distance will limit zBoost performance. Keep the
Base Unit off 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. The zBoost performs best when there
are no obstructions between the zBoost Base Unit and your mobile device.
SECOND: Position Base and Indoor Antenna
The Base Unit can be easily mounted on a wall by rst removing the bracket from the Base Unit
and using the provided mounting hardware to afx to wall. Connect the Indoor Antenna to the 15
feet of RG-6. Then, using the TNC-F Adaptor, connect the RG-6 to the Base Unit. The Base Unit
should be a minimum distance of 4-5 feet off from the oor so there is clearance for the Indoor
Antenna extension.
The Indoor Antenna should be mounted on a ceiling where increased coverage is desired. Keep the
Indoor Antenna off oor and at least 3 feet away from other cords, metal objects or other wireless
devices such as wireless routers or wireless access points. The zBoost performs best when there
are no obstructions between the Indoor Antenna and your mobile device.
The zBoost PRO 7500 ZBC745SL-CM requires at least 15 feet of vertical separation between the
Indoor Antenna and the External Antenna. Generally, increasing this distance (up to 40 feet) will
increase the performance and decreasing the distance will limit zBoost performance.
Wall Mounting the Base Unit
The Base Unit can also be easily mounted on a wall. The Base Unit should be a minimum distance
of 4-5 feet off 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
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.
THIRD: Run the Coaxial Cable
NOTE: Refrain from securing cable or drilling holes until the system has been tested.
The zBoost PRO 7500 ZBC745SL-CM includes 2 coax cables, 50 ft. for External Antenna and 15 ft.
for Indoor Antenna.
Connect one end of the 50 ft. cable to the base of the External Antenna. Run the coaxial cable
along a descending pipe or through a wall that leads closest to the location of the Base Unit.
Connect the remaining end of the cable to the Base Unit.
Note
Avoid placing the External 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.

zBoost®PRO 7500 ZBC745SL-CM Manual
7
Use the 15 ft. coax cable, along with the TNC-F adaptor, to connect the Indoor Antenna to the Base
Unit. See Base Unit Assembly picture above.
Should you need additional cable length, 15 foot extensions (Part #: YX030-15w) are available at
www.zBoost.com. Please note: Cable longer than 65 feet is not recommended.
FOURTH: Connect zBoost Base Unit to
Power
Connect the zBoost Base Unit to the power supply
and plug into a power outlet. When your zBoost
system is in place and fully connected, walk
throughout your home and verify that you are able
to reliably place calls. If the signal strength has
improved, your zBoost is working.
Upon initial power up, the LED will cycle RED,
GREEN and ORANGE for 30 seconds. After 30
seconds, a series of GREEN ashes will indicate
the quality of your setup. Following this, a solid
GREEN light indicates normal conditions. If it is not
solid GREEN, follow the instructions in the Base Unit
LED Indicators section. Adjustments may be needed
to optimize performance. If you nd the increased
signal coverage is acceptable, however, no
additional adjustments are needed. See “Base Unit
Light Indicators” on page 11 for more information.
Antenna Aiming
To get the maximum benet, you will want to take special care to make sure you point the antenna
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 or try our zBoost Signal Finder Android App. The
majority of the time a cell tower will hold more than 1 frequency band and/or service provider.
To aim the antenna for maximum signal, you will need a phone operating on the same wireless
network(s) in use at the install location.
Note: A 1 dBm increase is 25% gain in signal strength.
If you do not know which direction the best signal is coming from, once the unit is installed, rotate
the External Antenna in 90 degree increments while measuring the results inside the desired
coverage area.
1. Place the cell phone(s) 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 External Antenna to the optimum direction. If it is reading too high, move the phone
farther from the Indoor Antenna. (Note: if you’re using signal bars to measure signal strength,
turn off your LTE during this process)
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 External Antenna starting position ________________.
4. Rotate the External 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).
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.

Conrm That Your zBoost is Working Properly
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, home 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.
Improving Your Coverage Area
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 External Antenna to a higher location in the attic or outside.
3. Purchase a External Antenna upgrade at www.zBoost.com.
Note: Using a signal meter or an antenna application on a smartphone is a more accurate way to
measure a stronger signal than the bars on a phone.
Upon initial power up, the LED will cycle RED, GREEN and ORANGE for 30 seconds. After 30
seconds, a series of GREEN ashes will indicate the quality of your setup. Following this, a solid
GREEN light indicates normal conditions. If it is not solid GREEN, follow the instructions in the
Base Unit LED Indicators section. Adjustments may be needed to optimize performance. If you nd
the increased signal coverage is acceptable, however, no additional adjustments are needed. See
“Base Unit Light Indicators” on page 11 for more information.
Note
Cell phone signal bars are approximate and vary from
phone to phone. The 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 Manufacturer’s rated output power of this equipment is for single carrier operation. For
situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB,
especially where the output signal is re-radiated and can cause interference to adjacent band users.
This power reduction is to be by means of input power or gain reduction and not by an attenuator at
the output of the device.

Frequently Asked Questions
What can I expect my cell phone signal range and strength to be inside my home?
The closer you are to the base, the stronger the signal. This will vary with different conditions. Some
of the conditions that will affect 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. The degree of improvement will depend upon many factors. The 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?
The zBoost unit will not help your WiFi service. This unit is designed to work with wireless PCS and
Cellular phones and devices. The WIFI in your home operates on a different frequency.
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, 3 dB is a signicant increase of 2x,
6 dB is 4x, and 10 dB is 10x. On a four bar phone, one "bar" equals about 10 dB. (Note: For best
reading, turn off LTE)
• The increase in signal you will see depends upon:
• The level of signal at the Signal antenna (outdoor)
• The care of the antenna placement (two feet away from metal, adequate antenna separation
[15 feet recommended])
• The signal already present inside (related to building losses)
• The distance of your phone/device from the Base Unit (signal spreads or diminishes rapidly
with distance.)
There are usually several cell phones in use at one time in my home, will your product boost
all of our signals simultaneously?
The zBoost PRO 7500 ZBC745SL-CM 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 products will not work for you. Also, keep in mind if your
best signal is 1 bar at the External Antenna, your coverage will be limited to one or two rooms. You
could improve that with an upgraded antenna. (See page v).
Where should I put my Indoor Antenna to get the best coverage?
The Indoor Antenna is the component that amplies the signal inside. You should mount your
Indoor Antenna on a ceiling where signal coverage is most needed. The farther you are away from
the Indoor Antenna, the weaker the signal. The Indoor Antenna could be placed in the family room,
basement, or a central location.
Note: if you install the External Antenna too close to the Indoor Antenna, the system will shut down
(red light will blink). This is a normal condition for this scenario. It just means that you need to
ensure that you have sufcient distance between the 2 antennas; otherwise, it will detect feedback
or noise and will automatically shut down.
