An In-Vehicle Cell Phone Signal Booster is designed to significantly amplify the signal for a mobile device, especially in remote areas. In some cases, the device needs to be placed in the supplied cradle in order to receive the enhanced signal. Some boosters also work with tablets, hotspots, and other devices. All signal booster makes/models are reportedly compatible with the major cellular operators' networks. A booster kit generally includes: integrated amplifier, magnetic roof antenna with 10 feet of cable, DC power supply, cradle with adjustable arms (to accommodate any size phone), and dashboard and/or vent clip cradle mount. This product can reportedly be moved from one vehicle to another.
