ABSTRACT:
A television broadcast invention comprising an elongated vertical support, a plurality of transmission lines extending upwardly along the vertical support, a plurality of primary radiators spaced along the length of the vertical support and connected to the transmission lines for radiating vertically polarized signals, and a plurality of parasitic radiating elements disposed radially outwardly from the primary radiators for re-radiating the vertically polarized signals as elliptically polarized signals. The primary radiators are preferably open-sleeve dipoles mounted on and surrounding a central hollow mast and fed by transmission lines extending along the hollow interior of the mast.
