How It Works
The cellular signal is received by the antenna from the cell tower, it is then transmitted
through the outdoor SC-240 cable to the 4G LTE booster, which amplies and sends
the signal through the RG-58 cable which connects to the computer’s data cable (not
included) to your computer’s data card, sending the improved signal to your computer
through the data card. When the data card transmits, the signal goes through the data
cable, it is then sent through the RG-58 cable and amplied by the booster and
broadcast back to the cell tower through the antenna.

1. 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 dB 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 to test 3G and 4G data rates.
Step 1. Find the area with the Strongest Signal
The signal booster requires a minimum cellular signal of low –100 dBm. Signal readings
usually appear as a negative number (for example -85). The more bars you get, the closer
the dB gets to zero. Aim for a signal close to -50dB. Signals stronger than -50dB may
cause the booster to shut down. (see the graph on the next page). If installing the
SC-288W outside antenna, nd the area with the strongest cellular signal source from
your service provider by following the directions below. If you’re using the SC-700-S-S
magnetic mount antenna, nd a window location near your work station with the
strongest signal. You can also go to www.antennasearch.com to nd the general
location of carrier towers.
Note: You may need to change the location of your workstation to achieve the best signal.

Connecting to an Outdoor Antenna
Option:
Connect the Outdoor Antenna:
SureCall’s outdoor omni antenna SC-288W comes with equipment for mounting on a
vertical wall. For best results the antenna should be mounted in an upright position.
The antenna should be placed near the location you identied in the previous step for
the best possible reception. The best location will be clear of obstacles. Connect the
antenna cable to the “OUTSIDE” connector of the booster and tighten it. If using
another antenna other than a SureCall antenna, use the included adapter to connect
the cable leading from OUTSIDE connection to antenna.
Mounting the Outdoor Antenna:
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: The booster case may become warm during operation. This is normal. Press any key on your cell phone to refresh communication
with the base station.
