How It Works
The system operates through a three-step process:
- Outdoor antenna receives signal from cellular tower
- Coaxial cable transmits signal to repeater unit
- Signal booster amplifies the received signal
- Enhanced signal improves indoor cellular reception
Key Features
- Multi-band coverage: 850MHz, 1800MHz, 2100MHz
- High 80dB gain for maximum signal amplification
- 27dBm output power for extended coverage
- Automatic gain control with 31dB step attenuation
- Compact design: 165 × 130 × 40 mm
