signal amplifier mobile signal booster for DCS 1800 MHZ  

Cell phone signal amplifier is a products designed to solve the mobile phone blind signal. As the mobile phone signal is transmitted by electromagnetic waves to establish a communications link, the building of the barrier, in some tall buildings inside, the basement of some places such as malls, restaurants, places of entertainment such as karaoke OK sauna and massage, underground civil air defense projects, subway stations and many other places where cell phone signals can not reach and can not use the phone. Cell phone signal amplifier can solve these problems in a particular place as long as the installation of a mobile phone signal amplifier system, the entire range of mobile phone signals can be well used, staff or customers will get great convenience .

Your system should come with at least the following items:

1) Outdoor Antenna (goes outside the building)

2) Signal repeater

3) Indoor Antenna (goes inside the building)!

4) Coaxial Communication Cables

5) Connetor

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. More notes on Donor antennas here.

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. More notes on Indoor antennas and patterns here.

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.

Of course there are still a few more things to consider but in general, this is the basic procedure. For more information, please contact us.
