Why do you need to buy repeater/booster ?
Cell phone becomes especially helpful when people get into critical situations. In case of emergency a timely call can save somebody’s life.
Unfortunately, there are still some places where they can find themselves “out of coverage” ,no signal at all... Usually those places are either
too far from the cell phone base station or located inside underground constructions, for example:
· Parking lots, tunnels
· Big stores, office buildings
· Cars, boats etc.
· House in remote areas
How can repeater bring your mobile phone better signal?
•The outside antenna catches low signal from operator servicer’s base station and delivers it to cell phone repeater through the connection
cable (coax).
•After the signal is accepted by the mobile repeater, this device amplifies it.
•Then this amplified signal goes through the connection cable (coax) to the inside antenna.
•And after that, the amplified signal transmits to your cell phone.
• Finally, your cell phone will get good signal, never on and off
A regular cell phone repeater consists of: (full kit)
· 1 - Outdoor antenna like yagi antenna or panel antenna
· 2 - Indoor Omni ceiling antenna
· 3 - Power supply (DC 5v)
· 5 - User manual
· 6 - Cell phone repeater (included with power adaptor)
· 7. 10 meters outdoor cable and 5 meter indoor cable
How should you install repeater (very easy and simple):
Step 1: Use your mobile photo to test signal strength outside house or on roof, -70dbm is the basic requirement (full bar).
Step 2 Install outdoor antenna in that location and keep adjusting, point it to signal tower station, try to get best signal.
Step3: Run outdoor coaxial cable into building in a convenient location to connect with signal repeater.
step 4: Mount your indoor antenna with signal repeater
step5: Power up signal repeater device to check the signal inside, moving outdoor antenna until you get satisfied signal.
Note: Connect outdoor ANT port with outdoor antenna, connect indoor ANT port with indoor antenna, yagi antenna is mounted at a higher position. Both antennas should be
10 meters far away from each other at least.
Installation technique Supporting:
1.If still no signal receipt after installation, please check if outdoor antenna point to signal tower correctly or elsewhere has stronger signal and confirm signal strength achieve-70DBM.
2. When unable to call out, please adjust the direction of outdoor antenna.
3. If strength is not steady, please check if outdoor and indoor antenna is too close; please ensure outdoor antenna has distance of 10 meters at least, with a barrier and not in a same horizontal line.
4. Keep antenna and repeater far from windows.
5. Pls put indoor antenna in place which is above 1.5 meter high from floor, keep 4m distance from the mini repeater..
6. Packed the connector by waterproof glue, otherwise wet reduce the signal cover area.
