Product Detail

Why we should buy mobile 850/1800 dual band signal repeater

 

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 one can find themselves “out of coverage”. 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 etc

 



 

How is  mobile phone 850/1800 dual band signal repeater WORKING ?

 

 ?The outside antenna catches the low signal from the mobile base station and delivers it to the cell phone 

amplifier through the connection cable (coax).

?After the signal is accepted by the phone amplifier, the 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 the cell phone.
