Detailed Description:

Overview:
The S2GD-JF Dual Band Smart Mobile Signal Booster is a high-performance cellular amplification system designed to eliminate dropped calls, enhance voice clarity, and boost data speeds in areas with poor signal reception. Utilizing advanced smart technology, it automatically identifies and amplifies the two strongest available cellular bands, providing a seamless and stable connection for all your mobile devices.

Key Features & Specifications:

• Smart Dual-Band Operation: The booster intelligently scans for and locks onto the two most robust cellular signals in your area, optimizing both voice and data connectivity automatically.
• Comprehensive Frequency Support:
  • Band 1: 900/1800MHz
  • Band 2: 900/2100MHz
  • Band 3: 1800/2100MHz
  • Band 4: 2100/2600MHz
  • Band 5: 850/1900MHz
  • This wide range ensures compatibility with most 2G, 3G, and 4G LTE networks globally.
• High Gain Amplification: With a powerful gain range of 65-75dBi, it effectively pulls in weak outside signals and rebroadcasts a strong, stable signal indoors.
• Power Supply: Operates using an included 22V±3 DC power adapter for consistent and reliable performance.
• Compact Build: Designed with a sleek, low-profile form factor (24cm x 18.5cm x 2.5cm, 0.8kg) for discreet and flexible installation in any setting.

How It Works:

1. Outdoor Antenna: Captures weak existing cellular signals from the nearest tower.
2. Amplifier Unit (S2GD-JF): Boosts the captured signal strength with high gain.
3. Indoor Antenna: Rebroadcasts the amplified signal within your desired area, creating a strong coverage zone for your phones and mobile hotspots.
