Griffin ClearBoost Antenna-boosting Case for iPhone

This clever case conceals a built-in booster antenna that captures more of the available wireless signal and sends it to the internal antenna of your iPhone. The result is a better signal, especially in border areas—which translates to fewer dropped calls, wider coverage areas, and faster downloads when browsing through your cellular connection.

Nothing to plug in -- just snap iPhone into ClearBoost’s durable polycarbonate case. Your iPhone gets protection from real-world hazards, and its antenna gets a boost.

• Boosts the built-in antenna of your iPhone
• Fewer dropped calls, cleaner signal
• Wider service areas
• Physical protection against bumps and scratches
