SureCall Flare Cell Phone Signal Booster
Part number: SC-Poly-DT-O-Kit
Troubleshooting Steps
1) Check that the outdoor antenna and indoor booster are adequately separated. Having a wall or floor in
between the two will reduce interference and improve performance.
2) If interference continues, elevate the outdoor antenna higher than the indoor booster and create more
vertical separation between the two. For best performance, be sure to mount the outdoor antenna at
least 30 total feet from the booster and as high as possible.
3) Finding an outdoor location with consistent signal that the antenna can capture is important and will
improve the performance of the system. If signal is inconsistent, relocate the antenna to a better location.
4) If outside signal is weak or a larger indoor coverage area is desired, a high-gain yagi antenna (part #SC-
231W) is recommended to capture more signal from the tower.
5) If a longer cable run is needed, RG-11 low-loss coax cable is recommended (Part # SC-RG11-100 for a 100
ft run). Unfortunately, RG-6 cable at 75 or 100 ft will introduce too much loss and performance will suffer.
6) Check the booster and antennas for loose connections. If they are loose, be sure to tighten them for a
proper snug connection.
7) Check the coax cable for bends and kinks. Be sure that there are no sharp bends in the cable as this can
bottleneck the signal travelling between the outdoor antenna and indoor booster.
8) Move the indoor booster to the center of the room. Centrally locate the Flare indoor booster in the area
that you need the signal boosted.
9) Base unit lights: As long as there are no red LEDs, the booster is operating properly. Steady and flashing
green lights are normal operation for the booster.
10) Place a call in the room where the booster is located to confirm that your phone is receiving a boosted
signal. Please note: 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 near the booster.
Outside Signal Strength Impacts Indoor Coverage Area
Signal boosters are designed for locations that have useable cellular signal outside where the outdoor omni
antenna is located. Indoor coverage area is directly related to the existing signal strength available at the outdoor
antenna location.
 Boosters cannot create signal where there is none. Instead, the outdoor antenna captures existing signal,
amplifies it and rebroadcasts the boosted signal to an area of otherwise poor or non-existent coverage.
 If there is no signal outside the building for the antenna to capture, then unfortunately a signal booster kit
will not work at that location. There must be useable signal for the system to capture and amplify.
Indoor Coverage Area Expectations
Flare’s indoor coverage area will vary based on the available signal strength at the outdoor antenna location.
 1-2 bars outside ~1,000 square feet, 3-4 bars ~1,500 square feet, 5 bars ~2,500 square feet.
 If there is weak signal outside, SureCall recommends upgrading the outdoor antenna to a yagi directional
antenna or using a kit that includes a directional yagi antenna, such as the Fusion4Home Yagi/Panel.
