5 Band Cell Phone Signal Boosters 2G 3G 4G Line Amplifier Reduces Dropped Calls


Line Amplifier Description:

Boosts all 4G LTE and 2G, 3G signals for all networks
Improves voice calls and increases data speed for all cellular devices
Self regulating, easy to install, no maintenance required
Can be used with optional splitters and antennas to provide a very large coverage footprint
Recommended for locations within 10 mi. (15 km) from the nearest cellular tower


Indoor Five Band Signal Repeater (Cell Phone Signal Booster) series is an ideal solution for three wireless systems in small/medium businesses and home users looking to enhance indoor wireless connectivity. 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.

Line Amplifiers are specially designed to assist the Base Station (BTS) or Repeaters to compensate the system loss from in-building distributing cable, power splitter and directional coupler and extend in-building signal coverage, and improve flexible of in-building signal coverage system design
To meet the field strength requirements of in-building signal coverage system.

The repeater improves mobile signals with no negative impact on human health.

Line Amplifier Features:
1. Cost effective solution for weak signal zones, reduce drop/off calls.
2. Compact size, low power consumption, easy installation, great cover.
3. Support any cellular devices (voice & data & video)
4. High linear design, ALC function design, low interference to BTS.
