Abstract
Improvements in the construction of television antennas, characterized in that each antenna comprises at least two parallel tubes located in horizontal planes, separated a relatively small distance with respect to the length of said tubes, these being shaped so that they have a central part incurved and two relatively short marginal portions with respect to the length of the central part, these parasitic branch pipes serving, and at least two pairs of conducted branches located in a horizontal plane intermediate to the horizontal planes, in which said parallel pipes are located, these led lines converging towards a point located on a line parallel to the horizontal symmetry axes of said parallel tubes; in that the branches of a first pair of driven branches have one of their end portions electrically connected at two points integral with said parallel tubes and arranged symmetrically with respect to said line parallel to said horizontal symmetry axes of the parallel tubes, connecting the second end portion of each branch of said first pair electrically to one of the end portions of a branch of each of the other pairs of conducted branches, the second end portions of the branches of the other pairs of conducted branches being free, branches belonging to each of these other pairs of branches driven in alignment according to directions that form a relatively small angle with the direction of said horizontal axis of symmetry of the parallel tubes, and why the end portions of the conducted branches, located in the vicinity of said point of convergence, they are connected to the the antenna.
