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.

Signal coverage area :
1.Support Maximum coverage area is 2000 square meters.( Depend on the area condition)
2.One indoor antenna only use for about 200 square meters. (in open space).
If want to make all use of 2000 square meters which the host supports,
need to add more indoor antennas (about8-10) and power divider / splitter.Package included:
1 x GSM & DCS Dual Band Signal Booster.
1 x Power adapter
1 x Manual
1 x Log Periodic Antenna With 10 Meters Cable
1 x Planar Antenna With 3 Meters CableHow Booster/Repeater Works?
Repeaters 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.
The repeater makes the signal stronger in places with poor signal coverage such as:
1) Underground areas: basements, parking lots, tunnels;
2) Other places where cellular signal is shielded by metal or concrete walls:
offices, supermarkets, cinemas, hotels;
3) Places distant from the BTS like private houses.
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 through the coax cable to
the installed Repeater.
3) The Repeater 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.
Installation Approaches:
1) Fix up outdoor antenna reception on housetop
or outside the window and point it to the signal tower.
2) Connect outdoor antenna to “BTS” port in repeater machine through cable.
3) Connect indoor antenna(s) to “MOBILE’ port in repeater machine through cable also.
4) Plug power adaptor into AC power socket and finish installation.
Technique Supporting:
1) If still no signal receipt after activated repeater,
please check if outdoor antenna point to signal tower
or elsewhere have strong signal and check if strength achieve -70DBM.
2) If can not call out, please adjust the direction of outdoor antenna.
3) If strength is not steady, please check if outdoor & indoor antennas are too close.
Please ensure the outdoor and indoor antennas have distance of 20 meters at least,
with a wall between and not in a same horizontal line.
Note :
1.To use this product to enlarge your signal,
the outdoor signal where put outdoor antenna shall be as good as possible ,
the signal in your mobile phone shall be full and must be very stable for talking .
The product will not work good if your outdoor signal is not good or bad .
2.We will not bear any responsibility of your outdoor signal is not good .
And if your outdoor signal is not full,
for example, the full signal shown in your phone is 5 bars,
and you can only have it 4 bars ,then please think it over again before buy.
3.The kits here can max. support 200 square meters if does not have walls .
If you have different rooms ,it may work only for 1 room.
