For our Canadian customers, the Wilson 8* series will soon run out of stock. Before being replaced by the Wilson 46* series, these products were unregulated by the FCC and IC, therefore, are more powerful than today's regulated boosters.

These legacy boosters are legal and grandfathered into program, and are in very limited supply.

Wilson 815226 complete Sleek kit is designed for cars, trucks, vans, SUVs, RVs, and boats and comes equipped with a 4" magnet-mount antenna and basic cradle accessories. With dual band support (850/1900 MHz), this Sleek system is a great performer at a great price.  This +26dB gain cradle booster combines the amplifier with the short-range interior antenna into a compact housing for a truly portable solution.  This single-user booster requires the phone to be placed directly inside the cradle (black antenna surface touching the back of phone) for hands-free only boosting.  With adjustable arm placement and semi-soft antenna cover, the Sleek cradle will securely hold any size cellphone when mounted in vertical position.  It easily installs without tools or drilling and has a multitude of mounting options available.

This is a complete kit including all required components for out-of-the-box boosting performance.  This amplifier kit is most suitable for users with general vehicle reception problems.  Also consider our Amplifier-only 815225 for custom exterior antenna selection and the Sleek Car/Home/Office Bundle 815226-H for vehicle-to-building mobility.  For all car, truck, and marine kits visit our Vehicle Kits page.

Sleek installation is very user-friendly and shouldnÌ´Ì_ÌÎ̴̝åÈt take more than 30 minutes. Sleek amplifier systems have two separate components which need to be installed and connected: the amplifier cradle and the exterior antenna. The amplifier cradle includes both the amplifier and the interior Ì´Ì_ÌÎ̝ÌÎådirect-connectÌ´Ì_ÌÎÌÌ´å antenna in a convenient, phone-holding design.

First, install the adhesive mount in the desired vertical position of your dashboard (not on your air bag cover) and adjust the cradle arms to fit your phone. Allow 24 hours for the mountÌ´Ì_ÌÎ̴̝åÈs 3M adhesive to set before attaching the amplifier cradle to the mount. The included 5V car cigarette lighter power supply with a 3-foot USB/USB-mini cable will be used to power the amplifier. Additional 5V AC wall power supplies and 5V DC hardwire vehicle kits are available. Use the bottom mini-USB port on the cradle as the power port (so both power cable and antenna cable exit the cradle at the same angle from the bottom).

Second, install the magnet-mount exterior antenna (or optional trucker/marine antenna) in the desirable position in the center of your car roof or trunk (at least 12 inches away from other antennas and 6 inches away from windows or sunroof). The strong, rare-earth magnet will securely hold the antenna in place. The antenna cable is thin enough to feed under the door rubber seal and through the door frame.

Finally, connect the exterior antenna to the amplifier and power on the amplifier cradle. Once connected and powered, your system will boost any compatible phone/network. A green light on the side of the amplifier indicates optimal operation. A red light indicates that an automatic shutdown has taken place. This is either due to the exterior antenna and amplifier cradle being too close, or being too close to a cellular tower. The Sleek cradle systems require direct physical contact with the back of your cell phone, so you must use hands-free calling or the speakerphone on your device to benefit from the signal amplification.

The optional home/office accessory kit (included in some kits) allows for easy desktop installation and vehicle-to-building mobility. The amplifier-only option does not include an exterior antenna.

  1. Wilson 815226 amplifier kit ratings and reviews

    Posted by John O. in West TX boonies on 13th Mar 2014

    Am pleased so far with this product. I am on an oil rig site in west TX in the middle of no where. I am the only one with cell service out here. Without it I have none. My co-workers are all interested in it. You will probably have some orders because of my experience with it. Also wanted to commend the prompt shipping of this amp. I ordered this on Fri. afternoon and received it in Monday's mail. Very pleased.

  2. Great when off the grid ratings and reviews

    Posted by Stagecoach - now somewhere in the boonies on 21st Jul 2013

    We travel in our RV about half the year and are often camped far from a cell tower. Years ago I installed a Wilson Trucker Antenna on the RV and connected to a 2004 era LG Flip phone with an external antenna jack. That phone was also tethered to our laptop as a modem for internet. Now I get the same great signal strength with the Trucker + the Sleek with my Verizon iPhone. And I use the iPhone Personal Hotspot to connect to the internet. Now I can finally upgrade that old phone to a second iPhone.

  3. Works exactly as advertised ** Very satisfied ratings and reviews

    Posted by Dan/ Gardiner Mt on 31st May 2013

    Product is meeting the need we purchased it for very nicely. Magnet on included antenna does not seem to adhere well, but the product functions very well.

    The 815226 Booster is the best buy I have made this year.It does everything it says and more.Great price and great product.

  6. Got Bars ratings and reviews

    Posted by Unknown on 12th Jul 2012

    Where we live we can not receive any cell service, or the calls get dropped. With the Wilson Duel Band Cradle, no matter where we go, we have plenty of bars.

  7. Better than expected!!! ratings and reviews

    Posted by Unknown on 11th Jul 2012

    Got the unit delivered to my work address and thought I would give this unit a try.

    While sitting at my desk, with 2 bars showing on my iPhone 4S, I hooked this little baby up. I threw my phone in the cradle, put the antenna up on a shelf and within 1 minute I had 4 bars! I was pretty happy with that... but WAIT! My iPad 3 has 3G too, so I removed the cradle arms and held the cradle up to the iPad's antenna area and that's when the real surprise happened... I went from 1 bar to 4!

    Great product! Can't wait to use this at the cottage!!!

    P.S. I'm in Ontario, with Bell.

  8. WORKS lIKE THE OLD 3 WATT PHONES ratings and reviews

    Posted by Ken Scruggs on 21st Jun 2012

    I used it today with the 12" antenna & I have coverage now in remote places that I have not had since we had 3 watt annalog phones in the past. I am a forester & I am advertising this product to my colleagues. The only thing that is not working is the micro-mini USB Charging Adapter. It will not charge my phone. I don't know if there is a problem with the cable on the Sleek unit.
