The Mobile X6 is the highest power 50db gain mobile booster on the market. It will keep you connected where other boosters fail. It boosts signal to all cell phones and cellular devices within the booster's range simultaneously. This is a wireless booster that does not require a physical connection to the cell phone or cellular data device.

The Smoothtalker Mobile X6 Extreme Power Booster is the most technologically advanced wireless cellular signal booster made. It features proprietary "stealth tech technology" that prevents shutdowns from poor antenna placement and changing environment. This booster has 50dB of gain and provides coverage throughout your car, truck RVs, Boats, work trailers.

How it works:

The Booster captures the signal outside the vehicle and boosts it to the phone. It takes the weak signal from the phone and boosts it back to the tower. Boosts both voice and data simultaneously.

Where can this booster be used:

The Mobile X6 50dB is used primarily in vehicles and also in buildings. (Note: Building use will require the purchase of kits with 120Volt AC/DC power supply.)

How Large an Area will it Cover:

Coverage area is effected by two things. Outside signal and booster gain. Generally the booster will cover the whole space in a car or pick up truck. In the case where it is used in a boat or RV the range will be limited by the outside signal level.

Assessing your outside cellular signal level

How Far from the Tower

Mobile X650 is the most powerful wireless booster on the market and can keep you connected up to 35 miles from the nearest tower.

Use Signal Bar Indicator

Use the signal bar indicator on your cellular device to approximate signal strength as per the chart above. Note: Even if your device shows no bars or "no service" it is possible that there is enough cellular signal for a booster to achieve communication with the network.


  • Mount outside antenna in the center of the vehicle roof except in cases where a sunroof is present. In this case mount the antenna towards the back of the vehicle in the center of the metal portion of the roof.
  • Mount the inside antenna in the back of the cellular device or place in to the cradle.
  • Flashing green LED lights indicate gain reduction. If the green lights on the booster are flashing, please refer to the user manual for instructions.

STEALTHTECH TECHNOLOGY (proprietary Smoothtalker technology):

Mobile X6 50dB amplifiers and boosters use STEALTH TECH® to automatically control gain to eliminate feedback loop (oscillation) and strong signal overload from nearby towers. This will keep your booster working without unexpected shutdowns and at maximum efficiency.
