Hoekom het 'n motor TV boks twee tuners twee antennas nodig?

Met twee tuners, twee antennas, you can install the antenna on the left and right sides of your car. when the car is running fast, once one antenna missed the tv signal, another antenna will be as a backup, to ensure that tv picture is stable and has no mosaic.

If your local tv signal is not strong, maybe you should consider 4 tuners 4 antennae digital tv module.
