Pair of Wilson Cell Phone Boosters Solve Poor iPhone Reception on AT&T

by Andrew Garcia

The Sleek booster is meant for use in a car. This amplifier attaches to the dashboard, while the antenna is supposed to be attached to the top of the car.

The 4-inch Sleek antenna has a magnet in the base for a solid connection to metal.??íSince I tested the unit indoors instead of in a car, I mounted it upright atop a desktop switch on my window sill.

The cell phone under test must be mounted in the amplifier cradle, providing a direct connection needed to get a signal boost.

The left-most screen capture shows the signal strength before boosting. The lower right image shows signal strength afterward. No matter how Apple calculates bars, this is better—the Sleek boost meant 10 of 10 calls connected.

The cradle antenna can be installed indoors or outdoors, but should be positioned in an area with good signal strength from the cell tower. Here, I’ve stuck it to the window in our lab closet, using the included suction cups.

The DT Desktop amplifier acts as the middle man, boosting signal received via coaxial cable from the cradle antenna before passing it to the desktop antenna, which broadcasts signal to cell phones in the area.

The Desktop antenna connects to DT Desktop’s amplifier unit, and must be positioned to face away from the cradle antenna to avoid oscillation.

Standing within about 10 feet of the desktop antenna, I saw a 29 dB signal boost immediately after plugging in the DT Desktop amplifier. Suddenly, the iPhone can make a call.
