Abstract (en)
[origin: DE4408744A1] The invention concerns a group antenna for radio links with terrestrial radio locations comprising two or more individual transmitters which are mounted on the outer skin of a motor vehicle and of which at least one is a primary transmitter. A supply system connects the primary transmitter(s) to an antenna connection point. In order to obtain the desired directional diagram, impedances are inserted either into the transmitters at selected points thereof and/or inserted at the connection points between the primary transmitter(s) and the supply system and/or at selected points of the supply system.
