1. Install the antenna as far away from the ECU and sensors of the vehicle electronic systems as possible.
2. Install an antenna feeder at least 20 cm (7.87 in.) away from the ECU and sensors of the vehicle electronic systems. For details of the ECU and sensors locations, refer to the article on applicable components.
3. Keep the antenna and feeder separate from other wirings as much as possible. This will prevent signals from the communication equipment from affecting vehicle equipment and vice-versa.
4. Check that the antenna and feeder are correctly adjusted.
5. Do not install any high-powered mobile communication system.
