ABSTRACT:
The disclosed antenna is designed notably for the emission of television and radio broadcast signals in the decimetrical wavebands. It comprises:
a vertical, central supporting tube,
a plurality of identical radiating networks evenly distributed around the central tube, each consisting of a vertical bifilary line symmetrically supplying, supporting and coupling a plurality of horizontal dipoles evenly distributed along this bifilary line, and,
a system for the distribution of equiphase, equal power, identically and simultaneously supplying the radiating networks through a single coaxial supply line. The antenna has a reflector thus substantially reducing its weight and its windward surface as compared with standard antennas with panels generally used in this band. Advantageously, these antennas are superimposed and enclosed in a sealed radome which is substantially cylindrical and self-supporting and superimposable. This antenna gives an omnidirectional diagram with 0.9 dB between 460 and 860 MHz and can radiate 5 to 7 kW per antenna element.
