📖 Product Manual

Indoor Signal Repeater (Signal Booster) series is an ideal solution for wireless systems in small/medium businesses and home users looking to enhance indoor wireless connectivity. It is connected via coaxial cable to a Donor Antenna and Service Antenna. The Donor Antenna is placed outside where it has easy access to BTS signals, and the Service Antenna is placed in the building to extend coverage to blind areas. Automatic Gain Control (AGC) prevents saturation, maintaining high voice quality and avoiding network interference. Its super compact design and easy installation make it ideal for individual customers.

⭐ Key Features

1. Cost Effective
Reduces dropped calls in weak signal zones significantly.

2. Compact & Efficient
Low power consumption and easy to install with great coverage.

3. Wide Coverage
Covers approximately 3000~6000m² without obstructions.

4. High Linear Design
ALC function ensures low interference to base stations.

5. Universal Support
Works with any cellular device (voice, data, and video).

6. Digital Control
Equipped with a digital display panel for intelligent mode setting.

📦 Standard Package

🔹1x AC90-264V, DC 9V/5A power supply adapter

🔹1x AC power cord (EU/US/UK/SA/China standard)
