Why we should buy mobile signal repeater/ signal booster/ GSM amplifier :

 

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

 

 

A regular cell phone amplifier consists of:

• 1 - Outdoor antenna like YAGI antenna (including 10 meters standard cable) (you also can buy from us)
• 2 - Indoor omni antenna (you also can buy from us)
• 3 - 5 meters standard cable
• 4 - Power supply (DC 10v)
• 5 - User's manual
• 6 - Cell phone amplifier

 

 

 

How does mobile phone signal repeater  WORK ?

 

 

 

•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.

 

 

 

 

How to install repeater ?

 

1, Firstly, select an appropriate position to mount. The signal repeater is better to be mounted close to walls. At the position selected, punch a hole in the wall as shown in the diagram and aim the bolt at the hole. Then fasten and fix with expansion bolts.

 

 

2, Connect the Outdoor ANT Port with out door reverse antenna through radio frequency cable. In general, the reverse antenna is mounted at a higher position. Yagi antenna and panel antenna may be used. The main lobe of the antenna radiation is oriented towards the base station and the reverse antenna and base station antenna should be visible as possible.

 

 

3,Connect Indoor ANT Port with the ports of indoor covering system or indoor relay antenna. In general, the indoor covering system is composed of several splitters, couplers, expansion amplifiers and antennas and applied as per specific engineering design for the purpose of satisfying the signal covering demands in large area or complicated terrain indoor space. In the case of small area indoor space, the requirements for covering can be satisfied by using single relay antenna with the option of hanging antenna or ceiling antenna.

 

 

4, Finally, connect the power interface shown as in the diagram to 5V3A power adapter and power on the adapter with 220v AC. The signal amplifier installation is thus completed.
