1:The outside antenna catches the
low signal from the mobile base station and delivers it to the cell
phone amplifier through the connection
cable.
2: After
the signal is accepted by the phone amplifier, the device amplifies
it.
3: Then
this amplified signal goes through the connection cable to the
inside antenna.
4: Finally , the amplified strong signal transmits to the
cell phone via inside
antenna
Installation
Instruction:
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 outdoor 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 **0v AC. The signal amplifier installation is thus completed.
