GSM 850MHz/CDMA Signal Booster with Sucker Antenna

Model Number: S-SPB-0033 Brand Name: OEM Key Specifications/Special Features: DescriptionFeatures1. High-gain linear power amplifier2. ALC and AGC function technology3. Ultra-low noise receive amplifier4. There is no interference to the base station, right after the opening of the original system and the base station without the need to adjust parameters5. Stable and reliable electromagnetic compatibility design6. The base station does not cause an increase in background noise, but will not lead to a decline in the quality of the base station communications7. With full-duplex communication mode8. Dispel the heat effective reasonable, the structure is pretty, the volume is suitable

Install repeater
1. Step 1: use your mobile phone to test signal strength outside house or on roof, -70dBm is the basic requirement (full bar)
2. Step 2: install outdoor antenna in that location and keep adjusting, point it to signal tower station, try to get best signal
3. Step 3: run outdoor coaxial cable into building in a convenient location to connect with signal repeater
4. Step 4: mount your indoor antenna with signal repeater
5. Step 5: power up signal repeater device to check the signal inside, moving outdoor antenna until you get satisfied signal
6. Note: connect outdoor (BTS) port with outdoor antenna, connect indoor ANT (MS) port with indoor antenna, outdoor antenna is mounted at a higher position. Both antennas should be 10 meters far away from each other at least
7. Indoor and outdoor antenna must be separated by wall

Working
1. The outside antenna catches the low signal from the mobile base station and delivers it to the cellphone amplifier through the connection cable (coax)
2. After the signal is accepted by the phone amplifier, the device amplifies it
3. Then this amplified signal goes through the connection cable (coax) to the inside antenna
4. And after that, the amplified signal transmits to the cell phone

Technical support
1. If still weak signal receive after installation, please check if outdoor antenna point to signal tower correctly or elsewhere has stronger signal and confirm signal strength achieve-70dBm.
2. If still have no signal after installation, please check our device power adapter whether connected perfectly and if connectors connect well.
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. Packed the outdoor connector by waterproof glue, otherwise wet reduce the signal cover area
