Important Separation Guidelines: For optimal performance and to prevent signal interference, maintain the following distances between the outdoor and indoor antennas:

  • Veqetandina Horizontal: Greater than 3 feet (0.9 meters).
  • Veqetandina Vertîkal: Greater than 2 feet (0.6 meters).

4. Operasyon

Once installed and powered on, the Atcall C5 booster will automatically begin to amplify the available cellular signal. The system requires at least one bar of existing outdoor signal to function effectively. It is designed to work with smartphones, tablets, and other cellular devices from all supported U.S. carriers.

The booster operates by receiving weak signals from nearby cell towers via the outdoor antenna, amplifying them, and then rebroadcasting the stronger signal inside your vehicle through the indoor antenna. This process improves voice call clarity, reduces dropped calls, and increases data transfer speeds.
