1. Device in antenna units (1) for transmission respectively reception, of electromagnetic signals of different polarizations, consisting of at least two antenna elements (3-6), and feeder networks (13,17) for feeding the antenna elements. The feeder networks comprise a primary feeder network (13) which is arranged for direct feeding of at least one of said antenna elements (3,6) with signals of a first polarization, and at least a second of the antenna elements (4,5) with signals of a second polarization. There is also a secondary feeder network (17) arranged to mutually connect those antenna elements which through the primary feeder network are directly fed with signals of different polarization, whereby all of the antenna elements are fed with signals of all the different polarizations. <IMAGE>
