Antenna Connection
In-car digital TV reception varies from vehicle to vehicle and the installer may
need to try several mounting positions to determine the best one which provides
strong and stable signal reception in your vehicle.
Antenna Location
To extend the reception area, we recommend that one antenna is mounted at
the front and one at the rear of the vehicle. Please refer to the diagram below for
some recommended locations.
