I INSTALLED THE BOOSTER AND MY SIGNAL
STRENGTH IS STILL WEAK
In order to correct a weak signal; essentially you have the options of:
• Adjust the aim of the donor (outdoor) antenna or replace it with a higher
gain antenna.
• Move the server (indoor) antenna.
• Increase the number of server (indoor) antennas.
• Reducing the attenuation values you chose when setting the manual gain
control.
I CANNOT MAINTAIN CALLS, MY SIGNAL
STRENGTH FLUCTUATES
If you find the booster is working but drops calls or delivers fluctuating signal levels,
the most likely cause is oscillation between the donor and server antenna(s).
Determine the status of the cellular booster led alarms. If so there is insufficient
isolation between antennas. You can either increase the distance between antennas
or place barriers between them to attenuate the signals or adjust the manual gain
control settings.
A second cause for this symptom is poor cable connections. Confirm that all cable
connections are tight and secure.
A third cause may be interference from other cellular service providers operating in
the same frequency bands. If their signals are stronger than the cellular signals you
want to receive from the cell tower. In this case the unwanted signal needs to be
attenuated either by repositioning or re-aligning the donor (outdoor) antenna, or by
using barriers (buildings, trees, etc) to block the signal.
