Difference in power. 12 volt dc verse 110 ac. Also the broadcast signal is much more narrow with the vehicle version. Must be within about 12 inches of booster although directions state 30 inches. The home version has a larger broadcast range but receiving and broadcast antenna must be much further apart than vehicle model. If they get to close it causes a feedback loop.
Sorry, there was a problem. Please try again later.The vehicle line and the home line have a number of differences. To start the external antenna for the vehicle is omni directional to help pick up a signal while driving, the home external antennas are directional meaning you will need to aim it at the closest tower. A directional antenna will provide a stronger signal pickup due to this. Second, the boosters are designed to meet all the FCC regulations which are different for a vehicle and a home. For in vehicle use, a max gain of 50 dB is allowed. For in home use, a max gain of 72 db is allowed. Then we come to the internal antenna's, mobile antenna's are designed to cover a car/SUV where a home antenna's can vary from a single room to an entire house.
