INSTALLATION
Step 1. Find the Area With the Strongest Signal
Using your phone, identify the outside location with the strongest signal for placement of your outside antenna. Generally,
this is found above the rooine on the side facing your nearest cell tower and as high as possible – where the antenna can
‘see’ your cell tower. To nd the location of your carrier’s closest cell tower, go to www.antennasearch.com.
The coverage area that the booster provides is directly related to the strength of incoming signal received by the outdoor
antenna. Mounting the outside antenna where the signal is the strongest will provide the best results. Please note, if signal
is extremely weak where the outside antenna is installed, indoor coverage will be limited.
Note that Bars are not always a reliable measure of signal. The best way to conrm signal coverage is the ability to place
and hold a call.
Putting your phone in Field Test mode will also indicate what level of decibels (dB) your phone is currently receiving. Deci-
bels are measured in the negatives, and a score closer to zero indicates you have a better signal. A signal of -120 dB indi-
cates you have no service, while a score of about -50 dB means you have excellent signal strength
For specic dB signal measurements, use the methods below.
• Apple iPhones: Dial *3001#12345#* and press Call. In the top-left corner, a dB number appears instead of bars.
• Android devices: download the app “Network Signal Info” in the Google Play store.
