3. Setup Guide
Follow these steps for a successful installation. The entire process can typically be completed by one person within 30 minutes.
3.1 Pre-Installation Check: Outdoor Signal Strength
Before installation, ensure there is at least 1-2 bars (>-120dBm) of usable cellular signal outside your home or cottage. The booster amplifies an existing signal; it cannot create one where none exists. Use your phone's field test mode to check signal strength (refer to Section 5.3 for instructions).
3.2 Outdoor Antenna Installation
The directional outdoor antenna is crucial for capturing the strongest possible signal from the nearest cell tower. It should be mounted as high as possible on your roof or a pole, clear of obstructions, and pointed towards the cell tower.
- Identify Cell Tower Location: Use online resources or signal strength apps to determine the direction of your nearest cell tower.
- Mount the Antenna: Securely attach the outdoor antenna using the provided mounting accessories. Ensure it is stable and can withstand weather conditions.
- Aim the Antenna: Point the antenna directly towards the identified cell tower. Adjust its direction slightly while monitoring indoor signal strength for optimal results. The maximum communication distance to a cell tower is 3-5 miles.
- Run the Cable: Connect one end of the 60 ft RG6 coaxial cable to the outdoor antenna. Route the cable into your building, ensuring it is protected from damage and moisture. Avoid sharp bends in the cable.

3.3 Booster Unit Placement
Place the booster unit in a central location within the area where you need improved signal. Ensure it is in a dry, well-ventilated area, away from direct sunlight and heat sources. The booster unit should be connected to the indoor antenna.
3.4 Indoor Antenna Installation
The SignalBrick booster features an integrated indoor whip antenna, simplifying the setup by eliminating the need for additional indoor antenna wiring. This antenna broadcasts the amplified signal throughout your desired coverage area.
- Connect Indoor Antenna: The indoor whip antenna directly connects to the booster unit.
- Maintain Separation: To prevent oscillation (feedback), ensure a minimum vertical separation of 20 feet (6 meters) between the outdoor antenna and the indoor antenna. Horizontal separation may also be necessary depending on signal strength and building materials.

3.5 Connecting Components
- Connect the 60 ft coaxial cable from the outdoor antenna to the 'OUTDOOR' port on the booster unit.
- Ensure the indoor whip antenna is securely connected to the 'INDOOR' port on the booster unit.
- Connect the power supply to the booster unit and then plug it into a standard electrical outlet.
3.6 Powering On
Once all connections are secure, plug in the power supply. The booster will automatically adjust its gain for optimal performance. Observe the indicator lights on the booster unit to confirm proper operation.
4. Operating Instructions
The SignalBrick Cell Phone Booster is designed for continuous, automatic operation. Once installed and powered on, it will automatically detect and amplify available cellular signals. No further user intervention is typically required.
- Automatic Gain Control (AGC): The booster continuously monitors incoming signal levels and adjusts its amplification to prevent overload and maintain stable performance.
- Oscillation Elimination: Built-in features help prevent feedback loops between the indoor and outdoor antennas, ensuring efficient signal boosting.
- Power Saving: A better signal reduces the power usage of your mobile devices, potentially extending battery life.
You should notice an immediate improvement in signal strength on your mobile devices within the booster's coverage area. This includes fewer dropped calls, clearer voice quality, and faster data speeds.
5. Troubleshooting
If you experience issues with your SignalBrick Cell Phone Booster, refer to the following troubleshooting steps:
5.1 No Signal Improvement or Weak Signal
- Check Outdoor Signal: Ensure there is at least 1-2 bars of native signal outside your building. The booster cannot amplify a non-existent signal.
- Antenna Direction: Re-adjust the outdoor directional antenna. Even slight changes in direction can significantly impact signal reception. Use your phone's field test mode to find the optimal direction.
- Cable Connections: Verify all coaxial cable connections are tight and secure. Loose connections can lead to signal loss.
- Antenna Separation: Ensure adequate vertical separation (at least 20 feet) between the outdoor and indoor antennas to prevent oscillation. Increase separation if necessary.
- Power Supply: Confirm the booster unit is powered on and the power adapter is securely plugged into a working outlet.
5.2 Intermittent Signal or Dropped Calls
- Check Power: Ensure the booster unit has a stable power supply.
- Cable Integrity: Inspect the coaxial cable for any damage or kinks.
- Overload/Oscillation: While the booster has automatic features, extreme conditions might cause issues. Try temporarily disconnecting power, then reconnecting. If issues persist, increase antenna separation.
5.3 How to Check Frequency Band
Understanding the frequency band your phone is using can help diagnose compatibility or signal issues.
- For iPhone: Dial *3001#12345#* then press the call button. Choose 'All Metrics', click 'Serving Cell Info', and check 'Band Info'.
- For Android Phone: Download a network cell info app (e.g., "Network Cell Info Lite"). Open the app, choose 'GAUGE', and check 'BAND'.

6. Maintenance
The SignalBrick Cell Phone Booster requires minimal maintenance to ensure long-term performance.
- Cleaning: Periodically wipe the booster unit and indoor antenna with a soft, dry cloth to remove dust. Do not use liquid cleaners.
- Cable Inspection: Annually inspect the outdoor coaxial cable for any signs of wear, damage, or loose connections, especially after severe weather.
- Antenna Check: Ensure the outdoor antenna remains securely mounted and correctly aimed.
