Abstract
A high-power, end-fed, circular, non-coaxial waveguide UHF-TV broadcast antenna comprising a single-moded, circular, non-coaxial waveguide having an inside diameter dimensioned to support only the circular non-coaxial TE.sub.11 mode of energy propagation through the waveguide at the design frequency of the operating frequency band, the waveguide having multiple radiating elements removing energy from the waveguide at intervals along the length of the waveguide, and conductive means extending transversely across the interior of the waveguide at least in the regions between longitudinally adjacent pairs of the radiating elements, the conductive means being perpendicular to the electric field vector of the TE.sub.11 -mode energy having a desired polarization, for suppressing TE.sub.11 -mode energy that is cross-polarized relative to the desired polarization, the waveguide and the conductive means defining a feed port at one end of the waveguide for receiving UHF-TV signals having the desired polarization.
