LINE-AMPLIFIER INITIAL SETUP INSTALLATION & ASSEMBLY
During this process, you will connect the outdoor antenna, interior distribution antenna
and a Uniden Cellular cellular booster to the Uniden UL20 Line Amp as follows:
OUTDOOR SIGNAL ANTENNA
Place the outdoor antenna on the roof or peak of the building. Ideally, this antenna
should be placed high enough to ensure there are no physical obstacles directly in
its line of sight. Connect the outdoor antenna to the 50-ohm N-Type coaxial cable
and run the cable down to the Uniden cellular booster on the connection labeled
Outdoor
.
INTERIOR DISTRIBUTION ANTENNA
Identify an appropriate and centralized location for the interior antenna in the area
where you would like to improve the signal. Connect one end of the indoor cable
to the interior antenna and run the other end of the cable to the Uniden UL20 on
the connection labeled
Outdoor. If a splitter is required in the installation, it can be
connected on the cable run between the UL20 and the interior antenna.
CONNECTING THE UL20 TO THE UNIDEN CELLULAR BOOSTER
Run a cable from the connection labeled Indoor on the Uniden UL20 to the
connection labeled
Indoor
on the Uniden cellular booster. It’s important to try to
always maintain at least 15 to 20 feet of vertical separation space between the
indoor and outdoor antenna at all times to avoid oscillation and feedback.
UNIDEN CELLULAR BOOSTER PLACEMENT
You should place the cellular booster in an easily accessible, cool and well ventilated
location within the building. DO NOT keep the cellular booster in a location that is
continuously exposed to sunlight as it can overheat.
COMMISSIONING THE SYSTEM
Once everything has been connected and plugged in, you will need to switch ON
the power for the Uniden UL20 by pushing the power switch to the ON position.
Doing so will cause the
Power LED
light on the backside of the unit to remain lit
indicating the unit is properly powered.

Explanation of LED Light Indicators located on the rear of the unit
On the backside of the unit there are three LED lights labeled:
Alarm High, Power
and
Alarm
Low.
When the unit is plugged in, the
LED Power
light should be a solid green color.
Orange LED alarm lights
indicate the Line Amplifier is automatically adjusting the gain. In
which case, the Line Amplifier is functional.
Red LED alarm lights
indicate oscillation (feedback) is severe and additional distance
between the indoor and outdoor antenna is required. If the LED light(s) continuously stay
red, the Uniden UL20’s Automatic Gain Control will attenuate the signal strength in order
to stop the Line Amplifier from oscillating.
Green LED alarm lights
indicate the Line Amplifier is functioning properly.
* Three solid green lights indicate the Line Amplifier is functioning properly.
