Step 1. Make sure you have positioned the booster in a window with the strongest
signal close enough to an existing electrical outlet.
Step 2. Make sure you have sufficient cable length between proposed inside antenna
location and booster connector.
Installation Overview
Step 1. Find the outside area that has the strongest signal.
(See page 7 for instruction)
Step 2. Install the inside antenna.
(See page 8 for instruction)
Step 3. Mount the signal booster, connect the inside antenna cable to the signal booster, and
connect the booster to an AC power source. (
See page 9 for instruction)
Step 4. Configure gain settings on the signal booster if needed.
Before You Install
Installing Your Hardware
Step 1. Find the area with the Strongest Signal
The signal booster requires a minimum cellular signal of low –100 dBm to high –90 dBm.
Signal readings usually appear as a negative number (for example, -85). The stronger
the EZBoost signal, the closer it gets to zero. Aim for a signal close to -50 dB. Signals
stronger than -50 dB may cause the booster to shut down (see the graph below). Before
installing the outside antenna, find the area with the strongest cellular signal source from
your service provider by following the directions below. You can also go to www.anten-
nasearch.com to find the general location of your carrier’s towers.
Measure the strength of the existing cellular signal in various locations
• Apple iPhones: Dial
*3001# 12345#*
and press
Call.
In the top-left corner, a number appears instead
of bars.
• Android devices: download apps such as “Network Signal Info” in the Google Play store to measure signal
strength. Search check real signal strength to find other cell signal measurement apps.
• Internet: go to www.speedtest.net
2. Select a window sill location away from buildings, walls, trees, hills, and other terrain features that
can block or reflect wireless signals with the strongest signal.
Note:
Where you install your booster in relation to the carrier’s cell phone tower also determines signal strength. Although cell phone
carriers try to place towers for maximum coverage, local ordinances and terrain features can restrict tower locations, which can limit signal
strength at your location.
