BEFORE INSTALLATION
IMPORTANT. BEFORE YOU BEGIN.
IDENTIFY THE AREA OF STRONGEST OUTSIDE SIGNAL.
Since booster performance is largely determined by the signal strength received by your outside
antenna, it is important to identify the location of best signal for placement of your antenna.
The best location is generally found on the side of your home that faces your nearest cell tower and
as high as possible -- where the antenna can ‘see’ your cell tower. Better signal received by your
outside antenna means better booster performance inside. Conversely, the weaker your outside
signal, the more limited your coverage will be indoors.
If you’re unsure of the direction of your carrier’s closest cell tower, see page 9 for
suggestions.
DO NOT RELY ON CELL PHONE BARS AS AN ACCURATE MEASURING TOOL
Cell phone bars are an approximation of your signal that varies by phone and carrier. Placing
your phone in test mode or downloading an app that shows your signal in decibels (dB) is more
accurate. For help using this feature on your device, see “Taking signal measurements with your
phone” on page 7.
During planning, installation and testing, take multiple readings several minutes apart. Also, verify
that you can place and hold a call.
BETTER ANTENNA SEPARATION MEANS BETTER PERFORMANCE
Maintain a distance of at least 25 vertical feet or up to 50 feet of horizontal distance, especially if
sufficient vertical separation cannot be achieved. Also, make certain the antennas are aimed away
from one another.
