FIELD: radio engineering; reception of telecasting signals. SUBSTANCE: antenna has base 1, two permanent magnets 2, 3 semi-spherical in shape, facing each other with like poles, hollow rod 4 with different-size magnetic circuits 5, annular ring magnets 6, 7 mounted on rod 4, ferrite rods 8 made in the form of cone of revolution and mounted with their bases on external surface of magnets 2, 3, casing 9, and contact 10 for connecting coaxial cable. Resultant of antenna magnetic fields may vary both due to displacement of magnetic circuits 5 inside rod 4 and due to displacement of ring magnet 6. In the process, characteristics of magnetic fields formed at ends of magnetic circuits 5 vary and antenna matching with TV set is ensured within wide frequency range. EFFECT: improved matching of antenna. 3 cl, 1 dwg
