Preparing to Install zBoost
Overview
ank you for choosing zBoost. zBoost allows cell phone users to use their cell phones INSIDE. Like a
skylight that brings sunlight indoors, zBoost transports and ampli es the outdoor cellular signals inside.
By following the instructions in this user manual, you will be Extending Cell Zones™.
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 carriers 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 windows can a ect signal penetration into the building.
Using a cell phone operating on the same carrier network(s) of the install location’s occupants, check the
signal strength at roof level (where the External Antenna will be placed) in varying locations by placing your
phone in test mode to read dB signal strength.
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 External Antennas by identifying the
area of strongest signal. It can also be used to identify peak antenna alignment when connected directly via
provided cable.
Select External and Indoor Antennas and Determine their location
It is recommended that the External Antennas and Indoor Antenna have over 15 feet of
vertical and 20 feet of horizontal separation.
Use the information from your site survey (page 3) to choose an appropriate External Antenna (available
at www.zBoost.com) for your application. For example, a high-gain directional antenna is needed if the
outdoor signal level is low and also for larger indoor coverage needs. Mount the External Antenna as high as
possible, keeping it at it at least 2 feet away from any metal.
zBoost has several indoor antenna options (also available at www.zBoost.com).  e dome and directional
panel antennas are the most popular for in-building applications. For larger coverage areas, a high-gain
directional antenna is needed (see illustration below).
e indoor antenna is connected to the base unit using coax cable. A directional antenna should be mounted
on a wall facing the direction where increased coverage is desired. A ceiling mounted antenna should be
placed in the center of the desired coverage area.
Note: Follow the speci c antenna installation instructions included with the external and indoor antennas.
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 10). Always orient the Indoor and External Antennas pointing AWAY from
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.
Note
Warning.  is is NOT a CONSUMER device
It is designed for installation by FCC LICENSEES and QUALIFIED INSTALLERS. You MUST have an
FCC LICENSE or express consent of an FCC Licensee to operate this device. Unauthorized use may result
in signi cant forfeiture penalties, including penalties in excess of $100,000 for each continuing violation.
You MUST Obtain Express Consent of an FCC Licensee
Prior to the installation of an industrial signal booster it is imperative that you either be an FCC Licensee or
have express consent from all of the FCC Licensees for which signals you wish to rebroadcast.
See page 16 for a sample consent form and page 17 for licensee contact information.
Site Survey
Before installing zBoost, assess the signal outside of the building, at roof level or wherever you plan to place
the External Antennas. zBoost can only bring signal into the building when signal reaches the External
Antennas. If there is no signal, the zBoost will not work for you.
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.

each other. See page 5, Installing Your zBoost Product, for additional information.
Cable Requirements
Low-loss satellite cable (either RG-6 or RG-11 available at www.zBoost.com) is required. After installing the
External Antennas, run coaxial cable between External Antenna and Base Unit.  e recommended maximum
cable length run for RG-6 is 65 ft. and 120 ft. 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, run cable to make sure you know where existing electrical wiring is
located. Drilling into live electrical wiring could cause and electrical shock and sever the wire.
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).
Grounding the Directional External Antennas
e Directional External Antenna assembly must be properly grounded when it is installed outdoors.  is
will help protect the 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 External 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.
Pre-Installation Guidelines
• Always orient the External Antenna and Indoor Antenna away from each other.  is helps maintain
isolation between the antennas. Additional isolating materials may be necessary.
• Vertical separation helps increase isolation.
• Directional antennas provide better isolation than omni-directional antennas.
• Keep cable runs as short as possible to minimize loss.
• Nearby towers can cause overload.
• Avoid any drilling or nailing directly into the roof.  is could allow water to leak into the building and
cause damage.
• Choosing to mount the antenna into fascia will not compromise the roof and places the antenna up
high.
• If practical, do a soft installation of the equipment  rst.
Coax Cable
Exterior Wall
e zBoost YX741 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.

Installing Your zBoost Signal Booster
You MUST Obtain Express Consent of an FCC Licensee
Prior to the installation of an industrial signal booster it is imperative that you either be an FCC Licensee or
have express consent from all of the FCC Licensees for which signals you wish to rebroadcast.
See page 16 for a sample consent form and page 17 for licensee contact information.
Placement of the External Antennas
Choosing the best location for installation of the External Antenna provides the best performance and
the largest area of improved signal. Determine the location which provides the strongest signal using the
instructions found in the Site Survey section on page 3. Find the location which provides the strongest
signal strength and install the External Antennas at that location.
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 antenna mounting with the strongest received signal. It
can also be connected to the directional antennas to aim the antennas for maximum received signal.

Mounting of External Antenna(s)
When you have determined the location of the strongest signal, install the antennas to a mast or j-pole
(Outdoor J-pole Antenna Mounting Bracket, YX014 available at www.zBoost.com). Loosely connect the
antenna(s) to the mast to allow the antennas to be reoriented for strongest signal.
Follow the speci c antenna installation instructions included with the External Antenna.
Omni-directional External Antennas should be placed as high as possible in the area of strongest signal.
Directional External Antennas should be aimed at the cellular tower of the appropriate carrier.
e location of the tower can be determined by using any of the following methods:
1. Using a YX699 Signal Meter (available at www.zBoost.com), connect the signal meter to the antenna
using the cable provided with the signal meter. Rotate the antenna until the optimum signal reading is
determined and secure the antenna at that position.
2. Download the zBoost Signal Finder Android app on a phone using a cell phone operating on the
primary carrier network of the location’s occupants.
3. Go to www.OpenSignal.com. Enter the zip code of the installation site. Note the location of the
appropriate tower.
4. See the Antenna Aiming section of this manual. Once a soft system install is complete, follow the
instructions for aiming the antenna(s)
NOTE: e zBoost YX741 requires at least 15 feet of vertical separation between the Indoor Antenna and
the External Antennas. Generally, increasing this distance (up to 40 feet) will increase the performance and
decreasing the distance will limit zBoost performance.
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 carrier
To aim the antenna for maximum signal, you will need a phone operating on the same wireless network(s) in
used 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.
e majority of the time, a cell tower will hold more than 1 frequency band and/or carrier. If you are using
two external antennas - one operating on PCS band and one operating on the cellular band, both antennas
will generally point in the same direction.
1. Place the cell phone(s) (in  eld test mode) 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 signal reading displayed on the cell phone.
________dBm (A)
3. 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 signal strength. ______dBm (B)
5. Continue to rotate the antenna another 90 degrees in the same direction and record the phone signal
strength. _______dBm (C)
6. Again, rotate the antenna another 90 degrees in the same direction and again record the phone signal
strength. ________dBm (D)
7. If you desire to optimize further, then look for the two highest signal readings above and move the
antenna between these two points to  nd the highest signal 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).
Installing the Indoor Antenna
zBoost has several indoor antenna options.  e dome and panel antennas are the most popular for in-
building applications.
Follow the speci c antenna installation instructions included with the indoor antenna.
e indoor antenna is connected to the base unit using coax cable (see illustration on page 8). A directional
antenna should be mounted on a wall facing the direction where increased coverage is desired. A ceiling
mounted antenna should be placed in the center of the desired coverage area.
Note
Avoid placing the External Antennas 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.

Mounting the Base Unit
e Base Unit can also be easily mounted on a wall. Attach the Base Unit to a suitable wall surface using the
provided hardware kit.  e Base Unit should be oriented with the indicator light near the top of the unit.
Connect the RG-6 coaxial cable from the Indoor Antenna to the Base Unit.
Running the Coaxial Cable to the Base Unit
Coaxial cable is not provided with the YX741. After installing the External Antenna, you will need to run
coaxial cable to the Base Unit.  e recommended maximum cable length run for RG-6 is 65 ft. and 120 ft.
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 meeting room of a two-story o ce,  rst run the cable from
the roof down the stairs to the meeting 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).
Connect the YX741 Base Unit to Power Con rm at it is Working Properly
With everything connected and the Base Unit plugged in, you should walk throughout the area and see that
you are able to reliably place calls.
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 (page 10) for more
information.
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.
Improving  e 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 outside.
3. Purchase an External Antenna upgrade at www.zBoost.com.

Frequently Asked Questions
What can I expect the cell phone signal range and strength to be inside the building?
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, the placement of the unit and the antenna’s proximity to cellular towers.
You can expect that indoor coverage will be improved. People will be able to make calls where they 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 Wi-Fi signal?
e zBoost unit will not help WiFi service.  is unit is designed to work with wireless PCS and Cellular
phones and devices. WIFI operates on a di erent 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.
e increase in signal you will see depends upon:
•  e level of signal at the External 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 mobile devices from the Base Unit (signal spreads or diminishes rapidly with distance.)
There are usually several cell phones in use at one time in this office, will your product boost all signals
simultaneously?
e zBoost YX741 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.
Frequently Asked Questions
Where should I put the Indoor Antenna to get the best coverage?
You should install the Indoor Antenna where coverage is needed the most.  e Indoor Antenna is the
component that ampli es the signal inside.  e coverage area and direction is dependant on the type of
antenna used (directional or omnidirectional).  e further away the phone is from the antenna, the weaker
the signal.  e antenna be placed in a central meeting room, lobby, or other central location.
Note: if you install the External Antenna too close to the Indoor Antenna, the system will shut down (red
light will blink).  is is a normal condition for this scenario. It means that you must ensure a 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 the zBoost External Antenna?
e zBoost External Antenna should be placed at the highest point in order to “catch” the strongest signal.
is location will likely be on the roof.  e placement of the External Antenna is very important. It is best
to place this in an unobstructed area, preferably above the roof line.
Note: if you install the External Antenna too close to the Indoor Antenna, the system will shut down (red
light will appear).  is is a normal condition for this scenario. It means that you must ensure a su cient
distance between the 2 antennas; otherwise, it will detect feedback or noise and will automatically shut
down.
