Abstract
An adjustable inner antenna for tv receivers, characterized essentially by comprising the arrangement of two annular elements provided with a concentric arrangement and coupled by a diametrical difference between coaxial support points that allow the rotation of one of the rings, which represent both the dipole of the antenna itself, achieving by the displacement of the mobile element, a selectivity of fields of detection of extra-short waves: these rings present the appropriate profile and are mounted on an insulating support, whose base can behave in its interior the best arrangement of coils and transformers for their frequency and impedance and due effectiveness of the antenna.
