| Use a screened wire between the transmitter/receiver unit and the aerial. The screen must be connected to the unit and aerial end. At the same time ensure that there is a good and permanent earth connection between aerial base wire and vehicle body. |
| The transmission system must be tuned to prevent sheath waves on the aerial wire. This should be ensured by performing a power measurement to check and tune the radio communication system. |
| „Onglass“ aerials can only be fitted on vehicles without insulating glass. |
