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. Awesome product! ratings and reviews

    Posted by Travis on 5th Oct 2013

    I purchased this amplifier to use in the oil field. I do most of my traveling for work around the southern New Mexico region in the Delaware Basin. I am pleased to say this unit can boost my cell phone signal from no service to 4G LTE. It does seem to work better if I pull off of the road while using it. Some times the hilly roads can interrupt the signal coverage. I use this amp with the high gain antenna 301119.

  2. Good Results ratings and reviews

    Works great in most remote Wyoming. I wish it had a little differnt car mount. I don't care for the perminent glue mount. Would like the option of the type mount when you order. Good 3G I not have 4g in this area yet.
