______
Determine Signal Strength
Having an accurate measurement of signal strength in decibels
(dBm) is crucial when installing your system.
Decibels accurately measure the signal strength you are receiving.
Decibels are not linear: A seemingly small increase in dBm can
make a huge dierence in signal strength!
DECIBEL GAIN POWER INCREASE
3dB 2 times the power and signal amplification
6dB 4 times the power and signal amplification
10dB 10 times the power and signal amplification
12dB 16 times the power and signal amplification
20dB 100 times the power and signal amplification

Step 1: Find the dBm Reading
on Your Phone
All Other Phones & Alternate Methods
https://www.weboost.com/test-mode-instructions/
All Phones:
Keep track of the network (3G or 4G) phone is connected to.
Any signal readings you take are valid for that phone’s carrier. To get readings
from other carriers, you’ll need phones from each carrier.
When system is set-up, you can easily revert back to the “bar display” by
restarting your phone.

Step 2: Measure Signal
Strength: Inside Antenna
Turn o your cell phone’s WiFi to ensure you are checking the
cellular connection. The dBm reading will be refreshed every 30-60
seconds.
Want faster results? Once you have a reading, turn on airplane
mode. Wait 15 seconds. Turn o airplane mode. The signal strength
reading is refreshed.
Walk around your home/oce taking signal strength readings until
you find the area that has the worst reception.
Remember: Place your Inside Antenna in this poor signal area.
Connect the booster directly to the Inside
Antenna. Keep at least 18” of separation
between the Inside Antenna and the Booster
and face the Inside Antenna away from the
Booster.
Keep the Booster away from direct sunlight,
heat (<150°F), moisture and 6” away from oth-
er objects (for ventilation). Ensure the Booster
is near an outlet.

Please note:
The Outside Antenna must be at least 20’ away (horizontal or vertical) from the
Inside Antenna.
Using the minimum required 20’ separation may result in reduced performance.
To maximize coverage area, if possible place the Outside Antenna directly above
the Inside Antenna.
If the Outside Antenna is outside the building, use the flat Window Entry Cable
to connect both rolls of cable. You can use this option during set-up and/or
permanently.
______
Step 3: Measure Signal
Strength: Outside Antenna
IMPORTANT: This is the most critical step of the installation process
because it will determine the overall performance of the booster system.
Repeat the previous step OUTSIDE your home/oce to find best
available signal strength in dBm. This is where you should place your
Outside Antenna.
IMPORTANT: The further apart the Inside Antenna is located from the
Outside Antenna, the better. To determine the best location for your
Outside Antenna, note the dBm reading in a variety of locations:
Increase horizontal and/or
vertical distance over 20’
for better performance.

Step 4: Connect the System
Connect supplied cable from the booster to
the Outside Antenna. See 7.1.
Separate the Inside Antenna from the Outside
Antenna by at least 20’. See 7.2. The more
separation, the better!
Do not face the Outside Antenna and the
Inside Antenna towards each other. See 7.3.
If both rolls of cable are needed, use cable
connector. See 7.4.
If the Outside Antenna is outside the building,
use the flat Window Entry Cable to connect
both rolls of cable. See 7.5. You can use this
option during set-up and/or permanently if
you don’t want to drill holes through your wall.
Power up the Booster. To protect Booster
from power surges, connect to a power strip.
See 7.6.

Fix Any Orange Light Problems (orange indicates a cell
tower is close by)
If you are happy with coverage, orange lights don’t have to be resolved
Solid Orange = Band has shut o
Blinking Green/Orange = Band has reduced gain.
1. If the light is solid orange, the Outside Antenna must be adjusted (see below). Wait
10 seconds between adjustments for the lights to reset.
For Roof/Pole Mount Option = Rotate the Outside Antenna away from the
strongest cellular signal in small increments (45°) until the light turns green. Un-
plug and re-plug power supply.
For All Other Mount Options = Change mount location. For example, if the Outside
Antenna is a window mount, move the Outside Antenna to a wall outside the
building to see if the lights turn green. Un-plug and re-plug power supply.
2. If the light is blinking green/orange, re-locate the Outside Antenna. Un-plug and
re-plug power supply.
All Green Lights? = Band is set up correctly. Verify you
have good coverage.
If you have green lights, but poor coverage:
After each step, un-plug and re-plug the power supply
so the booster can update the signal reading.
!
Increase separation between Inside and Outside Antennas. Un-plug and re-plug
power supply.
Rotate the Outside Antenna in small increments (roof/pole mount only). Un-plug
and re-plug power supply.
Move the Outside Antenna to a dierent location. Un-plug and re-plug power
supply.
Change the method of mounting the Outside Antenna. Un-plug and re-plug power
supply.

To protect your system , you will want to purchase/install a lightening surge protector
(#859992). This is especially important if the Outside Antenna is mounted outside. To
purchase, call 866-294-1660 or visit weboost.com
After installing your system, check the lights after 24 hours to ensure no changes.
If the Outside Antenna is mounted outdoors, weatherproof connections 1” (25mm)
beyond where the connections begin and end. Cover with electric tape to protect
from UV rays.
Optional: To improve the aesthetic of your antennas use non-metallic paint.
If you haven’t already, be sure to register your product!

HOME 4G CELL PHONE SIGNAL BOOSTER
______
Specifications
Each Signal Booster is individually tested and factory set to ensure FCC compliance. The Signal Booster cannot be adjusted
without factory reprogramming or disabling the hardware. The Signal Booster will amplify, but not alter incoming and outgoing
signals in order to increase coverage of authorized frequency bands only. If the Signal Booster is not in use for five minutes, it
will reduce gain until a signal is detected. If a detected signal is too high in a frequency band, or if the Signal Booster detects an
oscillation, the Signal Booster will automatically turn the power o on that band. For a detected oscillation the Signal Booster will
automatically resume normal operation after a minimum of 1 minute. After 5 (five) such automatic restarts, any problematic bands
are permanently shut o until the Signal Booster has been manually restarted by momentarily removing power from the Signal
Booster. Noise power, gain, and linearity are maintained by the Signal Booster’s microprocessor.
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.
