INITIAL SETUP INSTALLATION & ASSEMBLY:

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

antenna and the 12V power supply to the Uniden UM50-4G booster unit as follows:

OUTDOOR SIGNAL ANTENNA

Please connect the magnetic base unit to the outdoor antenna and place it on the 

metal roof of the vehicle. Try to keep it as far away from the interior antenna as 

possible. Once you have found the desired positioning for your outdoor antenna, 

connect it directly to the booster on the connection marked “Outdoor”

DISTRIBUTION ANTENNA

Identify an appropriate location for the distribution antenna and keep it as far 

away as possible from the location of the outside antenna. Once you have found 

the desired position for your distribution antenna, connect it directly to the 

booster on the connection marked “Indoor”

BOOSTER PLACEMENT

You should place the booster in an easily accessible location within your vehicle 

i.e. Under the passenger seating, in the rear of the vehicle or any other location 

that keeps the booster hidden out of sight. Please DO NOT  keep the booster in a 

location that is continuously  exposed to sunlight as it can overheat.

COMMISSIONING THE SYSTEM

Plugging in the power will switch the Uniden UM50-4G ON causing the “Power” 

LED light on the backside of the unit to remain lit indicating the unit is properly 

powered.

INITIAL SETUP INSTALLATION & ASSEMBLY:

UNIDEN BOOSTER

Install the Uniden Booster in an area that is protected from the weather, properly 

ventilated and is away from excessive heat and moisture.

OUTDOOR ANTENNA AND MOUNTING POLE

The ideal location for the outdoor antenna is on the roof of the building or a mast 

structure. The antenna should be placed in a manner that allows it to capture the 

best possible cellular signal.

OUTDOOR COAXIAL CABLE

Connect the outdoor coaxial cable to the connection on the back of the outdoor 

antenna and run the cable to the Uniden Booster and attach it to the connector 

labelled “outdoor” on the Uniden Booster (use the included SMA adapters).

INDOOR COAXIAL CABLE (IF USED)

Connect the indoor coaxial cable to the connector labelled “indoor” on the Uniden 

Booster. Run the cable to the location of your indoor antenna and attach it to the 

connector on the back of the indoor antenna (use the included SMA adapters).

INDOOR ANTENNA

The ideal location for the indoor antenna will be the area of your property where 

you need to improve the signal most.

COMMISSIONING THE SYSTEM

Plugging in the power will switch the Uniden UM50-4G ON causing the “Power” 

LED light on the backside of the unit to remain lit indicating the unit is properly
