Reasons to Purchase Our Signal Repeaters
Signal Repeater are very effective equipment that can offset the covering shortage of the base station of the mobile network, expand the cover range of the base station and fill the signal blind zone to ensure the convenient and pleasant communication. The only requirement signal repeater need for all this is at least middle range signal outside this area.
If you are in such a situation and thinking about your own repeater, please bare in mind that all our products have a huge list of advantages:

How It Works
There are a lot of reasons for bad or low signals that your mobile phone accepts. One of the most spread are usually caused with the blind zones in the cell coverage, with the thick walls in the buildings, their remote location from the mobile base station, the location of the area below the ground, where the radio waves from a cell phone base station cannot reach the mobile phone.
Fortunately, we have a solution to all this problems caused with low and bad signals. Our cellular amplifiers successfully overcome them. They receive even a weak signal from the outside, and then amplify it into a strong signal inside the building, thus making your conversations over the phone pleasant and easy.
All our cellular amplifiers are designed to fulfill the idea of one and main principle:to fill the areas with the weak or bad signal and to amplify these low signals in order to provide you with the communication suitable for you.
Steps that the work of our cellular amplifiers.
1. The outside antenna receives the signal from the nearest mobile base station.
2. The outside antenna sends the received signal through the coax cable to the installed cellular amplifier.
3. The cell amplifier accepts the low signal and improves it.
4. The improved signal goes to the inside antenna through the connection coax cable.
5. The inside antenna send the improved good signal to your mobile phone.
All our cellular amplifiers work atfull duplex. It means that they not only receive the weak signal from the mobile base station and then divert to mobile phone after amplifier. They also receive the signal from your mobile phone and then send it to the mobile base station

1) Outdoor Antenna (goes outside the building)
2) Signal repeater
3) Indoor Antenna (goes inside the building)!
4) Coaxial Communication Cables
5) Connector

Step 2Temporarily 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 3Run coaxial cable into the building to a convenient location (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 6Connect 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.
