GSM Cell Phone Signal Repeater Booster Amplifier
Products Features
1. ALC ensure output level stable and adjustable continuously.
2. Low power consumption and avoid to interference to BTS.
3. LED indicate and judge to signal level of uplink and downlink.
4. AGC and MAC function.
5. Customized band selective.
6. With the amplified linear power, the intermodulation and and spuriousness are suppressed effectively.
7. Compact design, to easy or and convenient installation.

Steps that describe the work of Repeater:
1) The outside antenna receives the signal from the nearest mobile base station.
2) The outside antenna sends the received signal to the installed Repeater through the coax cable.
3) The Repeater accepts the low signal and amplified it.
4) The amplified signal goes to the inside antenna through the connection coax cable.
5) The inside antenna send the amplified good signal to your mobile phone
