(54)	Mounting of an antenna on a vehicle roof with maintained high voltage protection

(57) A system for vehicles is provided, comprising a first unit arranged on the outside of the vehicle and a second unit arranged on the inside of the vehicle, and communication means to provide a communication contact between said first and second units. The communication means further provides a galvanic separation between the first and second units. Thanks to this separation, a reliable high-voltage protection is achieved without distorting the communication signals. The invention is particularly useful for internet solutions for trains.
