The Sleek is an affordable universal cell phone signal booster for use in vehicles. It significantly improves the performance of most cell phones including today’s popular smart phones— iPhone, BlackBerry, Android phones and others. It greatly reduces disconnects and dropouts while speeding data transfer rates on 2G and 3G networks. There is also a kit available that allows the same increased signal in the home or office. The Sleek amplifies a phone’s signal to and from the cell tower. This ensures fewer dropped calls and dead zones. It provides 1.8 watts of output power, where the typical cell phone only produces about one-fifth of one watt. Combined with the included outside antenna, the Sleek can boost a phone’s signal by as much as 20 times. The Sleek’s patented technology prevents this amplified signal from interfering with any cellular or other RF communication networks. The Sleek combines a compact form factor and affordable price point with output power and receiver sensitivity previously found only on much bulkier, much more expensive cell signal boosters. In addition , the Sleek is compatible with phones and networks of all North American wireless carriers (except Nextel/iDen), including GSM, CDMA, 2G, 2.5G, and 3G.
