Installing the Signal Antennas
Choosing the best location for installation of the Signal Antennas 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. This location will be typically found on the roof.
Warning: Avoid placing antenna near metal such as wiring, A/C ducts, truss plates, etc. When
attaching the cable to the antenna, run the cable straight down from the antenna. Avoid
draping the coax near the antenna.
When you have determined the location of the strongest signal, install the antennas to
a mast or pole. Loosely tighten the antennas to the mast to allow the antennas to be
reoriented for strongest signal.
Antenna Aiming
the antenna(s) 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. For more
information see the manual.
Running the Coaxial Cable to the Base Unit
Coaxial cable is not provided with the YX645. After installing the Signal Antennas and
connecting them, run coax cable to the location in the home where you plan to install
the Base Unit. The recommended maximum cable length run for RG-6 is 60' and 120' 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 an electrical
shock and sever the wire.
installing the Base Unit and Indoor Antenna
The Base Unit can also be easily mounted on a wall using the included mounting bracket
there is clearance for the Base Unit antenna extension.
The Indoor Signal Antenna connects to the F-TNC adaptor.Then, using the 15’ RG-6 coax,
connect the F-TNC adaptor to the Base Unit. It should be mounted on a wall facing the
direction where increased coverage is desired.
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
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
Should you desire to improve coverage, you may:
1.) Move the Base Unit and/or adjust the angle of the Base Unit antenna.
2.) Move the Signal Antenna to a higher location in your attic or outside.
3). Purchase a Signal Antenna Upgrade at
zBoost ®
Upon initial power up, a solid GREEN LED should appear indicating normal conditions. If
the increased signal coverage is acceptable, however, no additional adjustments are
needed. See LED Indicator section for more information.
Should you desire to improve coverage, you may:
• Relocate the Signal Antenna in order to capture a better signal – higher is usually
• Increase the distance between the Base Unit Antenna and the Signal Antenna.
• Purchase an upgrade antenna available at

FCC Information
Warning: Changes or modifications to this device not expressly approved by zBoost could void the user’s authority to operate the equipment.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If the equipment does cause harmful interference to radio or television reception, which can be determined
by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and receiver
• Connect the equipment to an outlet on a circuit different from that to which the receiver is connected
• Consult the dealer or an experienced radio/TV technician for help
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter. In accordance with FCC requirements of human exposure to radiofrequency fields, the radiating element
(antenna) shall be installed such that a minimum separation distance of 20cm (8in) is maintained from all persons.
Industry Canada Regulations
Canada IC: 5544A-YX545PCSCEL
This Class B digital apparatus meets all requirements of the Canadian Interference Causing Equipment Regulations. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause
undesired operation.
The term “IC:” before the radio certification number only signifies that Industry Canada technical specifications were met.
RF Exposure:
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 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.
Please note: This unit has been approved for use in Canada under RSS 131, however, consent for the use of this device to improve cellular or PCS coverage, must be
obtained through your cellular or PCS provider, prior to placing the unit in operation. Please refer to the Industry Canada document CPC 2-1-05, Section 6.1 available
or viewable at:
Cet appareillage numérique de la classe [B] répond à toutes les exigences de l’interférence canadienne causant des règlements d’équipement. L’opération est sujette
aux deux conditions suivantes: (1) ce dispositif peut ne pas causer l’interférence nocive, et (2) ce dispositif doit accepter n’importe quelle interférence reçue, y
compris l’interférence qui peut causer l’opération peu désirée.
Le fabricant nominale de la puissance de sortie de ce matériel est simple transporteur. Pour les situations lorsque plusieurs signaux porteurs sont présents,
l’évaluation devrait être réduite de 3.5 dB, en particulier lorsque le signal de sortie est ré-émise et peut provoquer des interférences adjacentes à la bande
utilisateurs. Ce pouvoir est de la réduction par le biais de la sortie d’alimentation ou la réduction de gain et non par un atténuateur à la sortie du dispositif.
