The booster amplifies existing signals; it cannot create a signal where none exists.1. Check Your Frequency Band: Carriers use multiple bands. Even if you see LTE on your phone, you must be receiving Band 12 or Band 17 (700MHz) from your nearest tower. How to check: Go to Settings > About Phone > Status > SIM Card Status (or Network) and look for LTE Band. If it shows 12 or 17, this booster is for you.2. Outdoor Signal Requirement: You MUST have at least 1-2 bars of stable signal outside your home (where the outdoor antenna will be mounted). If the outdoor antenna receives absolutely no signal, the booster cannot amplify anything.3. Antenna Separation is Mandatory: To prevent oscillation (interference), there must be a minimum vertical/horizontal distance of 32 feet (approx. 10 meters) between the outdoor Yagi antenna and the indoor whip antenna. Proper separation is critical for the device to function legally and effectively.Package Includes: - 1x High-Gain Cell Phone Signal Booster (Main Unit) - 1x Outdoor Directional Yagi Antenna (for capturing distant tower signals) - 1x Indoor Omni-Directional Whip Antenna (for broadcasting signal indoors) - 1x 50ft Low-Loss Coaxial Cable - 1x AC Power Adapter and Mounting Hardware - 1x Detailed User Manual with Step-by-Step Installation GuideUpgrade your connectivity today and stay connected wherever you are!
