Do a site survey before buying this amplifier! If you're purchasing this to use in just one location, we strongly recommend doing a site survey first to determine whether the amplifier will help your signal and performance and to give you an idea of what kind of results you can expect from it. Start here: Will an Antenna/Amplifier Help Me?

If your signal is extremely poor (-108db or worse), an amplifier may not help you. There must be some usable signal available for the amplifier to boost for it to be effective.

Now there’s a mobile signal booster that works with virtually EVERY network – the Sleek 4G from Wilson Electronics. This powerful signal booster helps you stay connected by providing a strong reliable signal in weak-signal areas, reducing lost connections and speeding data rates. It boosts both voice and data communication – making it perfect for phones and wireless hotspots.

The Sleek 4G works with all devices on most conventional 2G, 3G, and 4G networks in the US and many more around the world. Wilson signal boosters feature cell site protection technologies refined over more than a decade of research and development. Optional indoor accessory kit (sold separately) allows use at home or in the office. FCC type accepted.

How it works: The antenna (sold separately) picks up the cellular signal and sends it through the cable to the cradle amplifier. The signal is then boosted and pushed out to the phone or device sitting in the cradle.
