ABSTRACT:
An improved antenna assembly, wherein: the opposing end regions of the dipole halves are each electrically connected to a respective connection line; the connection lines lead to two amplifiers; the outputs of both amplifiers are connected to the two inputs of a transform, whose output is at least indirectly electrically connected to a connector, a coaxial connector; one or more filters are provided; the filters are positioned between the connection lines and the connector terminal; the filter or filters is/are designed to suppress mobile radio frequency ranges and/or to protect broadcasting signals.
