The magnetic antenna included in the kit takes the signal from the nearest cell tower and transmits the signal to the booster unit, which amplifies the signal and transfers it to the patch antenna for spreading the signal inside the vehicle.
Based on need, the car booster can improve both calls and data, only calls, only data.
Installing a car booster is a super simple process since it is a plug-and-play device. The car booster comes with 2 antennas and a booster unit itself. The magnetic antenna is placed outside of the car, and the patch antenna, which is made of sticky material is placed inside together with the booster unit anywhere in the car. Quick installation materials and 24/7 tech support are always available to support in case of any technical and non-technical questions.
