Product Description

4G LTE cell phone signal booster

Certification CE0700 and RoHS


This Series Signal Repeater is designed for solve indoor coverage problem where signal is weak or unavailable,it can boost signal strength and ensure reliable coverage for cell phones.You can get a better call experience and faster data download speed,while can save your phone battery life.

Coverage area up to 3000-4500 m² 




A typical repeater system consists of a donor/outdoor antenna that receives and transmits signal from nearby cell towers, coaxial cables, a signal repeater, and an indoor rebroadcast/service antenna.

It can used in Home,Office,School,Apartment, Hospital,Basement, Hotel,Underground car park,Department Store,Commercial Center,Stadium etc.

4G Lte Cell Phone Signal Booster


1.Elegant and Compact design,good isolation and heat dissipation for long time operation.

2.Built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals.

3.31dB MGC(Manual gain control) 1dB one step available for both uplink and downlink to adjust the gain value for proper coverage during installation or maintenance.

4.Limit output power for both uplink and downlink to avoid deep self-oscillations from interference BTS.

5.Wide input power range,low power consumption.

6.With good IMD3,it can have more antennas for covering without affect towers.

7.High linear design,the intermodulation and and spuriousness are suppressed effectively.
