Application situations

 Mobile Signal Booster is specially designed for the “blind zones” of offices, family rooms, underground

parking garage, cars, lifts, elevators, factories, bars,supermarkets, mountain areas,marines, deserts,

high ways,tunnels,etc, where the signal is very poor. Or in spite of full bar signals on the mobile phone,

there is a break in voice leading to call clarity problem. Simply place the mobile phone booster in such

places, you'll be astonished with the huge gain in both the incoming reception and outgoing transmission

levels as the mobile signal booster goes to work!

Your system should come with at least the following items:

1) Outdoor Antenna (goes outside the building)

2) Siganal repeater

3) Indoor Antenna (goes inside the building)!

4) Coaxial Communication Cables

5) Connetor

6)Power Splitter

Steps:

Step 1 Start by taking your phone up to the roof or other location outside to find where the signal is strongest.

Step 2  Temporarily mount the Outdoor (outside) antenna in that location. You may need to adjust and move the antenna later.

Step 3  Run coaxial cable into the building to a convenient loaction (attic, etc.) where you can also get standard power for the Signal Repeater.

Step 4  Place the Signal Repeater in that location and connect the coaxial cable to the Outdoor Side of the Signal Repeater and the Outdoor antenna.

Step 5  Mount your Indoor (inside) antenna in a productive location. You may need to adjust or move the antenna later.

Step 6  Connect coaxial cable between the Indoor antenna and the Signal Repeater output port.

Step 7   Power up the system and check for signal inside the building. If needed, tune system by moving and or pointing the Outdoor and Indoor antennas until they get the most signal possible.

Step 8  Secure all antennas and cables, securely mount the Signal repeater and clean up the installation.
