Abstract (en)
An antenna having high gain and narrow beamwidth over broadband VHF and UHF portions of the electromagnetic spectrum comprises a biconical radiator/receiver (2) mounted substantially at the focal point of a parabolic reflector (3). Typically, the biconical radiator/receiver and the parabolic reflector are mounted on a supporting rod (1). Director rods (4,5) may also be provided on the supporting rod, the director rods being mounted on the side of the biconical radiator/receiver opposite to the reflector. The invention provides a low-cost high-gain antenna particularly suitable for television reception.
