Antenna Connection
DVB-T reception will vary from vehicle to vehicle and you may have to try several
mounting positions to determine which position provides the strongest signal in your
vehicle.
We recommend for one antenna to be mounted at the front and one at the rear of the
vehicle.
Please refer to the Diagram below for some of our recommendations:
Rear Location Front Location
(1) Behind the Rear Bumper. (providing it’s not Metal)
(2) Bottom of Rear Windscreen
(3) Top of Rear Windscreen
(4) Top of Front Windscreen
(5) Bottom of Front Windscreen
(6) Behind the Front Bumper. (providing that it’s not Metal)
Once a suitable position is found, carefully route the antenna cables to the receiver unit
and then connect to the Antenna Inputs. (Optional +12V Blue Wire not required for
active Antennas)
