Abstract: A low cost broadband antenna system particularly suitable for television reception is described wherein the feed line includes a pair of conductors mounted in insulated manner one above the other above a support boom with the conductors having a fixed separation from each other and from the boom, a fixed conductor diameter and boom dimension maintaining a constant impedance along the line. Dipoles extend transverse the longitudinal axis of the boom and are symmetrically disposed about the axis with the dipole half elements on the same side of the axis successively connected alternately to the first and second conductors of the pair.
