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.
