• Sucient SC-400 ultra low loss interior/exterior cable (for boosters above 65dB).
• Sucient SC-240 ultra low loss interior/exterior cable (for boosters 65dB and
below).
• Up to 6 internal antennas (such as the SC-222W, omnidirectional domes and/or
SC-248W at panel by SureCall).
• Grounded surge suppressor for DC power
1.4 - How It Works
The DualForce booster amplies cellular signals from the nearest tower to phones in
a building and from those phones back to the tower to compensate
for weak reception caused by distance, topography, building structure, and/or other
reasons.The booster receives the signal from an outside antenna, amplies that sig-
nal, and then rebroadcasts it via the interior antenna(s) where it is picked up by cel-
lular phones, modems, and data cards. The interior antennas also pick up signals
from cellular devices and pass them to the booster. The booster amplies these
signals and passes them to the exterior antenna for rebroadcast back to the tower.
