Product Description

Single Cell Phone Signal Boosters WCDMA Multi Band Repeater Donor Antenna

3G2100 Band selective analog repeater is designed for installations in offices, warehouses, factories, shopping malls and business centers. It is easy to install, offers high call quality, high gain, a simple prompt software setup makes installation of this repeater an easy plug and play task. With the control panel in front of the repeater, the repeater status can be known during installation.


Fixed Band can suitable for different operator, not disturb other operator frequency.
Eliminate dropped calls and increase data speeds with a signal booster.

It is connected via coaxial cable to Donor Antenna and Service Antenna, Donor Antenna is placed outside the building where it has easy access to BTS signal, and the Service Antenna is placed in the building where it can extend radio coverage to the blind area. And Automatic Gain Control (AGC) to avoid the Booster from over saturation, therefore maintaining a high voice quality and avoid adding interference to network. With good looking & super compact design also make it attractive. Besides, it is easy installation feature is also for individual customers to install the booster by themselves, and it does not need much professional knowledge and instrument.
Downtown areas of the cities, congested with many high-rise buildings are usually the weak or blind areas.
Do not dismantle machine, maintain or displace accessories by yourself, because in this way, the equipment may be damaged or even get an electric shock.
