FIELD: radio engineering; transmitting antennas for synchronous radio broadcast in medium-frequency band.
SUBSTANCE: proposed directional medium-frequency antenna characterized in narrow directivity pattern has at least two rigid vertical components in the form of metal masts or towers grounded at their base. Vertical and longitudinal wire components are introduced to reduce metal input, vertical ones being suspended from rigid vertical radiating components by means of longitudinal wire components whereto respective vertical wire components are attached to form electric contact; longitudinal wire components connected to different vertical components are joined together by means of insulators; bottom end of vertical wire component disposed near one of extreme rigid vertical radiating components is connected to signal source and bottom ends of remaining vertical wire components are grounded.
EFFECT: reduced metal input of antenna.
