BEFORE INSTALLATION
1. Make sure you have positioned the booster close enough to an existing electrical outlet.
2. Ensure adequate separation between the planned locations of the booster and inside antenna
(see page 8).
3. Make sure you have sufficient cable length between the inside antenna location and booster location.
Installation Overview
Step 1. Find the window that has the strongest signal. Note that the EZ 4G and the desktop antenna should
have a separating wall.
a) If installing in a two story home or office place the EZ 4G upstairs and install the inside antenna
downstairs.
Step 2. Mount the signal booster, connect the inside antenna cable to the signal booster, and
connect the booster to an AC power source.
a) For optimum performance, place the EZ in a corner of the window.
Step 3. Install the inside antenna.
EZ 4G INSTALLATION
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 EZ signal, the closer
it gets to zero. Aim for a signal between -65 and -85 dB. Signals stronger than -50 dB may cause the booster
to shut down. Find the area with the strongest cellular signal source from your service provider by following
the directions below. You can also go to www.antennasearch.com to find the general location of your carrier’s
towers.
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.
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
