Can this booster be used in a mobile environment? Such as a car?

This product is not recommended for mobile environments as it utilizes a donor antenna and server antenna to receive and transmit signal. The donor antenna should be placed at the point of strongest signal, preferably outdoors and positioned high. The donor antenna is then aimed in the correct direction with assistance of a downloadable app. The server antenna should be separated from the donor antenna as much as possible.
