How It Works
SureCall’s FlexPro is a high-quality bidirectional signal booster that enhances cellular
signals to areas that are prone to weak cellular coverage.
FlexPro 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, amplied 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, amplied and then
sent to the cell tower via the outside antenna.

Omni Antennas are ideal for
topographies with minimal
obstacles. They oer 360˚
hemispherical coverage
Yagi antennas are for targeted
areas and capable of reaching
cell towers up to 30 miles away
Dome antennas are for a central
location with 360˚ coverage
Panel Antennas allow optimum
reception to targeted areas

Step 1. Make sure you have positioned the booster close enough to an existing
electrical outlet.
Step 2. Make sure you have sucient cable length between proposed outside antenna
location and booster connector.
Step 3 Make sure you have sucient cable length between proposed inside antenna
location and booster connector.
Installation Overview
Step 1. Find the outside area that has the strongest signal. (See page 8 for instruction)
Step 2. Install the outside antenna in the area identied in step 1. (See page 9-11 for instruction)
Step 3. Install the inside antenna. (See page 11-12 for instruction)
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 instruction)
Step 5. Congure gain settings on the signal booster if needed. (See page 14 for instruction)

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.
If your FlexPro Kit includes an outside omni antenna and you can only achieve reception
of one bar or less, you may need a FlexPro yagi antenna which is capable of targeting
carrier antenna towers that are up to 30 miles away. Call or email SureCall for assistance.
Signal readings usually appear as a negative number (for example, -85). The stronger
the signal, the closer it gets to zero (see the graph below). 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 measure signal
strength. Search check real signal strength to nd other cell signal measurement apps.
• Internet: go to www.speedtest.net
2. Select a location away from buildings, walls, trees, hills, and other terrain features that can block
or reect 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 cell 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 CM400 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.

FlexPro’s 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.
