Wie Sie Ihre externe Antenne richtig positionieren und ausrichten

To ensure your booster provides optimal signal amplification, the external antenna must be positioned correctly. Here's a step-by-step guide to help you aim the antenna toward the nearest mobile base station.

Start with a Signal Check

Before you begin the antenna positioning, check the signal strength in your location:

• Signal Bars: Use the signal bars on your phone as a basic indicator.
• Precise Measurement: Since the scale of signal bars can vary between phone models, we recommend using a specialized app for a more accurate reading of the signal strength in dBm. For detailed instructions on how to measure signal in dBm with your phone, refer to our article here.

Find the place with the best external signal strength.

Locate the Nearest Base Station

To ensure the external antenna is pointing in the right direction, it should be aimed at the nearest mobile base station from your service provider. You can use mobile antenna mapping services like CellMapper to identify the nearest base station and its direction.

Set Up the Booster System

Follow the instructions in the user guide or refer to the article here to install your booster and antennas properly.

Important: Ensure sufficient separation between the outdoor and indoor antennas to avoid interference. Do not power on the booster until the antennas are positioned at an adequate distance from each other.

The external antenna should be oriented toward the nearest base station of your mobile provider, but it should point in the opposite direction from the indoor antenna to minimize interference. This ensures both antennas function effectively without impacting each other’s signal quality.

Measure the Signal Level Inside Before Turning On the Booster

Before you power on the booster, measure the signal level inside the building. Using the app, check the signal strength in dBm for more precision. This will serve as a baseline comparison after adjusting the external antenna.

Examples:

Position and Rotate the External Antenna

• Install the external antenna at the designated location, such as the roof or another optimal spot.
• One person should adjust the antenna direction, while another stays inside, monitoring the signal level both on the booster’s screen and in the app. Wait at least 1 minute after each adjustment to allow the signal to stabilize before retesting.
• Rotate the antenna 1/8th of a full circle (45 degrees) and repeat the signal test inside. Continue rotating and testing in all 8 directions (360 degrees).
• After testing all directions, compare the dBm readings. The direction providing the strongest signal (closest to 0 dBm) should be selected.
• Securely fix the antenna in that direction and ensure it remains in place.

This process ensures that you find the optimal antenna position for maximum signal strength.

Additional Tips:

• Mounting the Antenna
  We recommend mounting the external antenna on the side of the building, aiming away from the building. This will reduce potential obstacles and interference.

• Perform Testing in Pairs
  For efficiency, we recommend working with a partner — one person can adjust the antenna while the other monitors the signal.

By following these steps, you’ll ensure the external antenna is positioned correctly to maximize your booster’s performance.
