Installing Your Hardware
Step 1. Find the area with the Strongest Signal
Finding Your Strongest Cellular Signal
To send and receive cell phone calls you need to have an adequate cellular signal. This usually means
having to be somewhat close to a cell phone tower. Your cellular signal is measured in decibels (dB), which
represents the power of the signal. Signal readings appear as a negative number, for example -85dB. The
stronger your signal is the closer it gets to zero. As the illustration below shows a -50 dB signal reading is
very strong while a signal reading of -100 dB and above is very weak.
How to Determine Your dB Signal Reading
• Using an iPhone: Dial *3001#12345#*, a Field Test screen will appear press down on the home button
for a few seconds so your dB reading will appear in the upper left hand corner.
• Using an Android: Download the “Network Signal Info” within the Google Play store. Once installed, you
will be able to view your dB strength.
• Internet: Go to: www.speedtest.net to test your 3G and 4G data rates.

Step 2. Install the Outdoor Antenna
For best performance, be sure to place the outdoor antenna at least 75 feet from the indoor antennas.

indoor & outdoor antennas
Do not collocate antennas or operate the outdoor antenna with any other antenna or signal booster.
Installing Your Hardware
The omni antenna may be mounted directly to a surface or to a J-mount (not included) Outdoor omni
antennas receive and send signals in a 360º radius. If you are installing a Yagi antenna set it up facing the
cellular tower to find the nearest cell tower go to www.antennasearch.com. Place the antenna as high as
possible. Make sure that the mounting area has at least a 36-inch radius clear of obstructions and other
radiating elements. The antenna should be mounted in an upright position. See illustration.
1. Unscrew antenna from L-mounting bracket on antenna base with hands, or wrench, if needed.
2. Using vertical plate of bracket, mark position of desired placement with pencil or marker.
3. Unscrew nut on end of stucco screw and remove it along with lock washer and regular washer.
4. Place vertical plate into desired location and tap the screws head first, along with sleeve, into stucco
1⁄2” to 5/8” deep into place.
5. In this order, place washer, lock washer and nut on each screw and tighten until secure. When
tightening screw, sleeve will expand to secure plate. Screw antenna securely back onto horizontal plate.
6. Connect antenna to cable connector of one of the 75 ft. lengths of SC-400 cable and run along route to
planned location of your booster.
IMPORTANT
: For boosters enhancing T-Mobile’s AWS frequencies, the FCC has stated for consumer signal boosters operating as a fixed station in the 1710 - 1755
MHz uplink 2110 - 2155 downlink bands, the users or installation manual must contain the 30 foot height restriction requirements per FCC 27.50(d)(4).
