I.4 Antenna Installation
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.
Important Notes on Antenna Installation: for a better reception, please
place the rod antenna horizontally, and keep the rod antenna away from
metals.
Antenna Position
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.
Front Location Rear Location
(1) Behind the Front Bumper, provided that it is not metal
(2) Top of Front Windscreen, at least 5cm away from metal body (in car)
(3) Top of Rear Windscreen, at least 5cm away from metal body (in car)
(4) Bottom of Rear Windscreen, at least 5cm away from metal body (in car)
(5) Behind the Rear Bumper, provided that it is not metal
*Noted: The DTV signal of position (2) ~ (4) is generally better than position
(1) and (5). However, because the windshields of many cars are usually
equipped with film coating (containing metal), the actual signal reception will
be seriously degraded, depending on the extent of metal embedded within.

Antenna Cable Rounting
Once a suitable position is found, carefully route the antenna cables to the
receiver unit and then connect to the Antenna Inputs on the DTV receiver.
