INITIAL SETUP INSTALLATION & ASSEMBLY:

During this process, you will connect the outdoor antenna, interior distribution antenna 

and a Uniden Cellular Booster to the Uniden UP20 Pre 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 UP20 on the connection labeled

 Outdoor. 

CONNECTING THE UL20 TO THE UNIDEN CELLULAR BOOSTER

Position the UP20 in a cool dark and well-ventilated area and run a cable from the 

connection labeled indoor to the connection on your Uniden cellular booster labeled 

Outdoor.

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.

INTERIOR DISTRIBUTION ANTENNA

Identify an appropriate and centralized location for the interior antenna and connect 

it to your Uniden cellular booster on the connection marked Indoor. The Whip 

antenna can connect directly to the cellular booster where as the panel and dome 

antennas have to be connected to the cellular booster via a 50-ohm coaxial cable. 

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.

COMMISSIONING THE SYSTEM

Once everything has been connected and plugged in, you will need to switch ON 

the power for the Uniden UP20 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.

DIRECT CONNECT INITIAL SETUP INSTALLATION & ASSEMBLY:

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 one end of the 50-ohm N-Type 

coaxial cable and run the cable down to Uniden UP20 on the connection labeled 

Outdoor. 

CONNECTING YOUR CELLULAR DEVICE TO THE UP20

Run another cable from the connection labeled 

Indoor 

on the Uniden UP20 

amplifier directly to your data card or cell phone using the appropriate adapter (sold 

separately).

COMMISSIONING THE SYSTEM

Once everything has been connected and plugged in, you will need to switch ON 

the power for the Uniden UP20 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 on.
