The dual band signalamplifier amplifies the signal of 900MHz and 1900MHz frequency band.The whole system is composed of "receiving antenna + repeater+ retransmission antenna"; it is used to extend base station signals from outdoor to indoor, asto solve the problem of indoor signal being weak and no signal.Compared with the similar products, it has the advantages of better compatibility, higher gain, higher output power, better signal quality, wider coverage area, and higher level of intelligence.Its integrated with "intelligent"operation,whichmeans that it get into working statementas long as electricity is switched on.2. The Functional Features Of The Product
1.It is characterized by high gain, large power and wide coverage.
2.High Q value medium multiplexer + high suppressing acoustic surface filter combination achieves high isolationof the system.
3.Aluminum extrusion profiles have the characteristics of natural heat dissipation, long term operation and high reliability.
4.Automatic detection of antenna isolation, automaticadjustment of host gain, simple application;
5.Well monitored.Using LED instructions, the working state is clear at a glance.
3. InterfaceDescription1.BS port: RF cable connects to outdoor receiving antenna.
2.MS port: RF cable connects indoor "retransmission antenna".
3.DC24V:Power adapter DC plug (Can be customized).4. The Technical Specifications Of The Host

Installation map1.Installation of outdoor receiving antenna: receiving antennainstallation location should receive fine qualityofmobile phone signal.(≥-65dBm); using the eight wood antenna, logarithmic periodic antenna or outdoor planel antenna, the antenna faces the base station, fasten the wind proof, the joint waterproof treatment, the feeder enters the air conditioning hole or window, and the drip line prevents the rain from flowing into the room.2.Install the signal amplifier: main engine installation location should choose dry, ventilated, waterproof place, do not near heat source.3.indoor antenna installation: Use ceiling antenna or small plate antenna.The ceiling antenna is installed in the ceiling and overlay in all directions, or small plate antenna wall mounted, directional coverage, suitable for large deep garage, Factory.4.Installation note:Receiving and transmitting antenna isolation:
The isolation of outdoor antenna and indoor antenna is the premise to ensure the workingoperation of the main engine. The isolation distance between the two antennas should be≥10 meters.Staggered vertical height installation,The wall of the building can be used to improve the isolation.During Installation, such as mobile antenna, feeder connection, mobile phone card and other operations, do not have to turn off the main power supply.6. Abnormal Alarm Processing
1.Self excitation alarm: turn off the power supply of the singal amplifier, adjust the installation position of the antenna, and improve the isolation degree of the antenna receiving and sending.2. When the output status indicator is not lit, the receiving signal is weak. Please check the feeder connecting the outdoor antenna and adjust the directionof the receiving antenna.3.When the power indicator is not lit:If 1 lightis on, and another 1 isn't lit, then it is the host failure;If the 2 indicator lights both aren'tlit, it is the power adapter failure or power failure.
