Abstract

A TV antenna for interiors comprises a housing of flat­ tened cylindrical shape (1), in a dielectric material, which is rotatably mounted on a base (2), also preferably of cy­ lindrical flattened shape. Said housing contains a first dipole (13), of bent configuration, for the UHF band; a second dipole (14, 15) for the VHF band, also functioning as reflector element for UHF band; two or more director elements (16, 17) and preferably an amplifier circuit (21) connected with the di­ poles.
