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TRIOtransportsandampliesthe
outdoor2G/3Gand4Gdatasignal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.

Preparing to Set Up Your zBoost Product
Tools Needed
The following tools are needed to set up your booster:
• #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theunitinyourhome,makesurethatyouhavereliablesignalandfast/reliabledata
speedsoutside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itreachestheExternalAntenna.If
there is no signal, zBoost will not work for you.
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 have reliable, fast data speeds 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
limited to one small room. WerecommendplacingtheExternalAntennaoutsideand/or
purchasingazBoostupgradeExternalAntennaforincreasedcoverage(seepagev).
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®TRIO Xtreme ZB575X Manual

IMPORTANT: Before Installing, Note These Important Factors in Determining
Performance
1. 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.
If the antennas are too close together, a solid ORANGE light will appear on the Base Unit -
see the Base Unit Light Indicators section (page 11). To capture the best signal, place the
External Antenna as high as possible.
2. Position the External Antenna vertically and keep it at least 3 feet above any metal.
Additional Cable Requirements
IfthedistancebetweentheExternalAntennaandtheBaseUnitexceeds50feet,extensioncables
are available on our website. The included cable is RG-6.
Thetotalcablelengthshouldnotexceed65feetunlessupgradedcableand/orupgradedExternal
Antenna(seepagev)isused.AlongercableishelpfulonlyifitallowsyoutoplacetheExternal
Antenna in a location where you measure stronger signal.

Grounding the External Antenna
IftheExternalAntennaisplacedoutdoors,itmustbeproperlygrounded.(Seepagevfora
recommended grounding kit).
The setup 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
IftheExternalAntennaisplacedoutdoors,
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. Consult
a professional installer for more information.
Power Requirements
The Base Unit can be plugged into a standard 2 or 3 prong 110 VAC receptacle using the included
power supply. The power supply consumes less than 10W (less than 0.2A).For more information on
powerconsumption,see“TechnicalSpecications”onpage12.
Warning
The zBoost TRIO Xtreme 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.

FIRST: Mount 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.
Keepinmindthatifyourbestsignalisonebar,yourcoveragewillbelimitedtoonesmallroom.
Maximumperformancewillbeachievedwhentheantennaisaimedatthestrongestsignalfrom
your wireless provider. If you know the direction of your provider’s tower, simply point the antenna
in that direction. If you are unsure of the location of the nearest tower, loosely secure the antenna
to the mounting surface or mast (not provided) to allow adjustment or rotation around mast. Before
securingantennahardware,takecareinndingtheoptimumangleatwhichtoaimtheantenna–
See Antenna Aiming section on page 9 for further instruction.
Once you have determined the optimum location and
angle, connect the L-bracket to the antenna and secure the
antennabrackettoamast(notprovided)oraatsurface
using the provided antenna hardware.(see bracket assembly
illustration). Ensure that the antenna remains at least 3 feet
aboveanymetalobjects(suchaspipes,metalsiding,A/C
unit etc.) and parallel to the ground with the two holes on the
side of the antenna are facing down.

this option.
SECOND: Position the Base Unit
Assemble the Base Unit and Indoor Antenna and position the antenna vertically. This Base Unit
uses an omni-directional antenna that delivers signal in a circular pattern around the antenna. Place
the Base Unit in desired location – where you want to create a Cell Zone™ For the widest possible
signal area, it is recommended that you position the Base Unit near the middle of a room. The Base
Unitcanbeplacedonaatsurface(e.g.,abookshelf,desk,endtable,etc.)andperformsbest
whenlocatedatleast4feetabovetheoororapproximatelytheheightofacellphonewhenitis
typicallyinuse(avoidplacingtheBaseUnitontheoor).

BaseUnit(see“zBoostBaseUnitAssembly”above)andusing2mountingscrewstoafxtowall-
keeping the antenna vertical.
Remember, the zBoost TRIO 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.
THIRD: Connect the coax cables via the provided window entry cable
NOTE: Refrain from securing cable or drilling holes until the system has been tested.
ThezBoostZB575Xincludes2coaxcables(35ft.and15ft.)andawindow-entrycablefor
connectingtheExternalAntennatotheBaseUnit.Ifyoudonotplantorunthecablethrougha
window, the window entry cable is not needed.
To run the coax cable through a window: Connect the two provided RG-6 cables (35 feet & 15
feet) using the provided window-entry cable. Use the attached cables to connect the Base Unit and
ExternalAntennathroughawindow,positioningthewindow-entrycableatthewindowclosing(See
Option 1 on page 8).
To run the coax cable through a wall: Connect the two provided RG-6 cables. Then connect one
endofthe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 (See Option 2 on page 8).
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 the zBoost Base Unit to Power

FIFTH: 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).
Conrm That Your zBoost is Working Properly
When your zBoost system is in place and fully connected, walk throughout your home and verify
that you have fast, reliable data speeds. If the signal strength has improved, your zBoost is working.
Remember, coverage varies based on outdoor signal level, home construction, and antenna
placement. Coverage in adjoining rooms will be reduced by walls and building materials.

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 data 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experiencefaster,morereliable
data where you didn’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. 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 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.
The increase in signal you will see depends upon:
• ThelevelofsignalattheExternalAntenna(outdoor)
• The care of the antenna placement (two feet away from metal, adequate antenna
separation [15 vertical feet of separation is 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 mobile devices in use at one time in my home, will your product
boost all of our signals simultaneously?
The zBoost TRIO Xtreme 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asmallroom.You
could improve that with an upgraded antenna (See page v).
