A TV antenna relates to radio engineering and may be used as a universal TV antenna. The antenna contains an active dipole and passive dipoles with elements for extension of their electrical length. Single-turn extension coils are made in different lengths and one of said coils having capacitive load in the form of a metallic plate linked to middle of a turn. The antenna also comprises three sets of wide-band reflectors and directors adjusted correspondingly to low-frequency, middle-frequency and high-frequency range of TV –channels. The technical result is enhancement of coefficient of efficiency, a gain and antenna directional effect. |
