How It Works
SureCall’s TriFlex is a high-quality bidirectional signal booster that boosts cellular
signals for areas prone to weak cellular coverage.
The TriFlex works with two antennas:
• An inside antenna that communicates with your cell phone.
• An outside antenna that communicates with the cell tower.
Signals sent from a cell tower are received by the outside antenna, amplied by the
booster and then broadcast to your phone via the inside antenna. When your phone
transmits, the signal is sent to the inside antenna amplied, and then sent to the cell
tower via the outside antenna.

Step 1. Make sure you have positioned the booster close enough to an existing electrical outlet.
Step 2. Make sure you have sucient cable length between proposed outside antenna
location and booster connector.
Step 3. Make sure you have sucient cable length between proposed inside antenna location
and booster connector. Additional cable may be purchased from your dealer, if needed.
Installation Overview
Step 1. Find the outside area that has the strongest signal. (See page 8 for instructions if needed)
Step 2. Install the outside antenna in the area identied in step 1. (See page 9-11 for instructions, if
needed)
Step 3. Install the inside antenna. (See page 11-12 for instructions, if needed)
Step 4. Mount the signal booster, connect the outside and inside antenna cables to the signal
booster, and connect the booster to an AC power source. (See page 13-14 for instructions,
if needed)
Step 5. Congure gain settings on the signal booster if needed. (See page 14 for instructions, if
needed)

stations operating in the 1710-1755 MHz band are limited to a maximum antenna height of 10 meters above ground. Mobile
and portable stations operating in these bands must employ a means for limiting power to the minimum necessary for

Installing Your Hardware
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
more bars, the closer it gets to zero. Aim for a signal close to -50 dB. Signals stronger
than -50 dB may cause the booster to shut down (see the graph below). If you have
an omni type of outside antenna and your signal is too weak you may need a yagi type
antenna, which can be aimed at the closest antenna tower. Before installing the outside
antenna, nd 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 nd
the general location of your carrier’s towers.
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 mea-
sure signal strength. Search check real signal strength to nd other cell signal measurement apps.
• Internet: go to: www.speedtest.net to test 3G 4G data rates.
2. Select a location away from buildings, walls, trees, hills, and other terrain features that can block
or reect wireless signals (12-inch clear radius is recommended).
Note: Where you install your outside antenna in relation to the carrier’s cell phone tower also determines signal strength. Although cell phone
carriers try to place towers for maximum coverage, local ordinances and terrain features can restrict tower locations, which can limit signal
strength at your location.

Installing Your Hardware
Step 2. Install the Outside Antenna
1. Outside Omni antennas receive and send signals in a 360º radius. Yagi, or directional
antennas work best when pointed in the direction of your cell phone carrier’s tower.
Mount the outside antenna as high as possible. If you are installing a Yagi antenna set
it up facing the cell tower in the area where you located the best signal source (see
step 1 on the previous page).
2. Make sure that the mounting area has least a 12-inch radius clear of obstructions and
other radiating elements.
3. If the mounting area is prone to weak cellular signals or if the density of the roof and
ceiling partially block the signal, the booster will operate at its default setting of 65 dB
gain, be sure to place the outside antenna in a straight line at least 75 feet from the
inside antenna for best performace.
4. Do not colocate antennas or operate the outside antenna with any other antenna or
signal boosters.
5. Run the SC400 cable from the outside antenna to the signal booster. Do not connect
the cable to the booster at this time.
Note: see next page for outside antenna installation details.

TriFlex omni antenna comes with equipment for mounting on a vertical wall. For best
results the antenna should be mounted in an upright position.
Step 1: Unscrew antenna from L-mounting bracket on antenna base with hands, or
wrench, if needed.
Step 2: Using vertical plate of bracket, mark position of desired placement with pencil
or marker.
Step 3: Unscrew nut on end of stucco screw and remove it along with lock washer and
regular washer.
Step 4: Place vertical plate into desired location and tap the screws, head rst, along
with sleeve, into stucco 1⁄2” to 5/8” deep into place.
Step 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.

Note: If desired surface for installation plate is wood or concrete, wood or masonry screws for L-plate will have to be purchased separately.
