1. Увод и крајview
The GOBOOST Cell Phone Signal Booster is designed to enhance cellular signal coverage within homes and offices, supporting GSM, 3G, 4G LTE, and 5G networks across Band 2 (1900MHz), Band 4 (1700/2100MHz), and Band 5 (850MHz). This system is compatible with major U.S. carriers such as AT&T, Verizon, T-Mobile, and US Cellular. It effectively boosts weak indoor signals from 1-2 bars to 3-5 bars, eliminating signal dead zones and providing stable reception for fewer dropped calls, improved voice quality, and faster data upload/download speeds.

3. Подешавање и инсталација
Follow these steps for optimal performance. Proper installation is crucial for the booster's effectiveness.
3.1. Pre-Installation Check: Test Your Signal Band
Before installation, confirm your cell phone's working band to ensure compatibility with the booster (Band 2/4/5). This step helps avoid issues with incorrect band usage.
- За иОС: Dial *3001#12345#*, press call button, click 'Serving Cell Info', then check 'Freq Band Indicator'.
- За Андроид: Download 'Network Cell Info Lite' app, disconnect Wi-Fi, turn on data network, then check 'GAUGE' to see the signal band.

3.2. Outdoor Antenna Installation
The outdoor Yagi antenna captures signals from the cell tower. It must be placed in an area with a strong, unobstructed signal (stronger than -80dB or at least 3 bars). Point the antenna directly towards the nearest cell tower for best results.

3.3. Indoor Antenna Installation
The indoor panel antenna broadcasts the amplified signal throughout your desired coverage area. Mount it on a wall or ceiling within the area where you need improved signal. Ensure there is sufficient separation between the outdoor and indoor antennas (at least 33 feet horizontally and 20 feet vertically) to prevent oscillation.

Figure 3.3: This diagram illustrates the signal flow: the outdoor antenna receives signal, sends it to the booster, which amplifies it, and the indoor antenna broadcasts the boosted signal. Note the recommended distance between antennas.
3.4. Signal Booster Unit Placement and Connection
Place the signal booster unit in a central location, away from direct sunlight and moisture. Connect the coaxial cable from the outdoor antenna to the "BTS" port (Base Transceiver Station) on the booster. Connect the indoor antenna cable to the "MOBILE" port on the booster. Finally, plug in the power adapter.

4. Упутство за употребу
Once all components are connected and the power supply is plugged in, the booster will automatically begin to amplify the signal. The LCD display will show the signal strength for each band (Band 2, Band 4, Band 5), allowing you to monitor its performance. Green indicator lights confirm proper operation. The booster works with all mobile devices and users simultaneously, providing improved voice and data services.
