Distance between antennas through
a sunroof must be 5 feet or more.
Separation of the inside and outside antennas is very important. The metal roof
of the vehicle acts as a barrier and helps shield the two antennas from each other,
preventing oscillation (feedback).
If the vehicle has a sunroof, it is important to separate the inside and outside antennas by at
least five feet. This prevents the Signal Booster from overloading or oscillating.
Understanding the Signal Booster Lights
The power light will turn green when the Signal
Booster is successfully powered up. When the
800 MHz or 1900 MHz lights are lit green, the
Signal Booster is amplifying the outside signal.
If one or both frequency lights turn red, oscillation
is occurring and the Signal Booster has powered
down on the frequency with the red light to
prevent oscillation. The outside antenna needs to
be moved farther from the inside antenna. Move
the outside antenna on the roof of the car to the
rear of the car, but at least 8-12 inches from the
rear or side windows. Disconnect power from the
Signal Booster and reconnect power. This resets
the Signal Booster.
If the lights are now green, the Signal Booster is
working properly. If the red light is still on, move
the antenna farther away and repeat the process.
Always use a magnet-mount or roof-mount
antenna. Do not use a glass-mount antenna, as
oscillation may cause continuous shut-down of
the Signal Booster.
A blinking amber light in either the 800 MHz or
1900 MHz position indicates overload from the
cell tower. The Signal Booster has temporarily
shut down and will automatically reset when
overload is no longer detected.
