TROUBLESHOOTING
The booster you have is a dual band booster, essentially it is 2 boosters in 1. One for the 1900 (high) MHz
frequency range and one for the 850 MHz (low) frequency range. The LED alarm lights represent the status
of the booster on each frequency. When the lights are green the device is operating normally meaning that it
is not experiencing any oscillation (feedback) and it is boosting the signal at maximum power. When the LED
lights begin to change color from green to orange to red, it means that that particular frequency is experienc-
ing some oscillation (feedback).
If the oscillation is too excessive the booster will shut down for that particular frequency. The booster will still
work for the other frequency. Carriers use both the 850 MHz and the 1900 MHZ, some towers will transmit
both frequencies and some just one. This is why you may be getting full signal while the booster has shut
down one of the frequencies.
Oscillation is caused when the indoor (distribution) antenna sends a signal back into the outdoor (signal)
antenna. Similar to a PA system, when the microphone gets too close to the speaker it causes feedback. This
will occur if your antennas are too close together, or the indoor antenna is pointed at the outdoor antenna.
Make sure you have adequate separation and some type of shielding between the antennas (usually your roof
or a cement wall is good enough).
IMPORTANT NOTES
The 2 most important things to look for when setting up your system is:
By capturing the best input signal you will be able to enjoy the maximum coverage and best quality signal
inside where your distribution antennas are located. The better the input signal, the better the output signal.
In order to nd the best input signal, you want to place your outdoor (signal) antenna as high as possible with
the least amount of obstruction between the antenna and the cellular base tower. A clear line of site is ideal.
Isolating the signal from the antennas is done by ensuring that the antennas are not pointing to each other
and by having enough distance or barrier shielding in between them.
A good input signal (the best you can find)
1
Isolating the outdoor (signal) antenna from the indoor (distribution) antennas so they do not
feedback into each other.
