Connector (optional) - for additional
Before installation, ensure adequate separation between the locations of the outside antenna and Inside antenna – at least 25 ft.
1. FIND AREA OUTSIDE WITH STRONGEST SIGNAL
Identify the outside location with the strongest signal. Generally, this is found on the side facing your nearest cell tower and
as high as possible.
Note that bars are not always a reliable measure of signal. The best way to confirm signal coverage is the ability to place and
hold a call. For specific measurements, use the methods below to see your phone's signal as a dB measurement. Note that
decibels (dB) usually appear as a negative number where numbers approaching to 0, are stronger signal (eg. -100 dB would
be considered a weak signal while -65 dB a strong signal).
Apple iPhones: Dial *3001#12345#* and press Call to enter test mode and identify your signal in dB instead of bars.
Android devices: download the app "Network Signal Info" in the Google Play store.
This signal booster requires a minimum cellular signal reading of -100dB at the location of the outside antenna. Signal
between -70dB and -90dB is recommended for best performance.
Please note: Signal stronger than -50dB may cause the affected frequency bands to turn off.

2. INSTALL THE OUTSIDE ANTENNA
Once you have located the area of strongest signal, mount the antenna to a pole or pipe (not
included) at the highest possible elevation. The directional Yagi antenna works best when
facing the direction of your carrier's cellular tower. For help finding the location of your
carrier's closest cell tower go to www.cellreception.com.
To install the outside antenna, assemble the u-bolt, bracket, nuts and washers to a pole or
mast, as shown in the illustration. Keep the connections loose enough to allow the antenna
to rotate until the optimum direction is found.
Note: The outside antenna may be installed on a variety of pipe angles. Ensure that the
mounting area has at least a 12-inch radius clear of obstructions and other radiating
elements and orient the antenna vertically with the drip hole at the bottom.
Once the outside antenna is secured to a pipe or pole, connect one end of the provided
50 ft. coax cable to the antenna and tighten the connection.
3. INSTALL THE SIGNAL BOOSTER AND INSIDE ANTENNA
Choose a location for mounting the directional panel antenna on vertical surface. The
antenna should be at the approximate height of your cell phone when in use and facing a
central area where signal is needed. Please note: Be sure to provide enough separation from
outside antenna - at least 25 ft. Also, the outside and inside antennas should face away from
one another.
Using the plate, mark position of desired screw placement and screw mounting plate into
place with the slide panel protruding towards you (see panel antenna illustration below).
Slide antenna securely onto mounting plate.
To install the booster, select a location that is near the inside panel antenna and a working
AC outlet. Use the supplied screws or appropriate screws for surface of mounting location
and drill through screw tab holes on booster (see Booster Components Diagram illustra-
tion) and mount the booster to a wall.
Connect the inside antenna and booster by connecting one end of the provided 20 ft. of
coax cable to the inside antenna and the other end of the cable to the booster port marked
"INSIDE" and hand-tighten the connection.
Next, connect the outside antenna and booster by connecting the remaining end of the 50 ft. cable leading from the outside
antenna to the port of the booster marked "OUTSIDE".
4. CONNECT POWER
Connect the AC power cord to the booster and plug into a 110V AC power outlet. Once
the booster has been completely assembled, turn the booster's power switch on.
Note: If the Power LED does not turn ON or the Alert LEDs continue to flash, see the
Troubleshooting section. This booster is rated for 5-15V input voltage. DO NOT use
the booster with a higher voltage power supply. This can damage the booster, cause
personal injury and void your warranty.
CHECK AND OPTIMIZE SYSTEM, IF NEEDED
Place a call in a location you have previously experienced poor signal and confirm
that your phone is receiving a boosted signal.
The gain dials on the booster should always be at maximum level unless a control
light is FLASHING RED-YELLOW. Additionally, the gain should only be reduced if other
recommended actions do not resolve the issue
In any case, the first action should be to increase the antenna isolation between the
inside and outside antenna as much as possible and restart the booster.
