FIELD: antenna equipment.
SUBSTANCE: invention relates to antenna devices, specifically to ultra-wideband antennas with vertical polarization and circular pattern in horizontal plane, and can be used in transmitting devices of information transmission systems, in particular used as transmitting and receiving antennae for radio communication with waved or basic radio stations. Collinear antenna has a base and a radiating part connected to it, including at least two symmetrical vertical dipoles connected by supply lines. Antenna is equipped with radiotransparent casing made of fiberglass, in which radiating part is placed. Each of the dipoles consists of two metal stepped sleeves facing each other by smaller-diameter sides interconnected by polytetrafluoroethylene-made bushings.
EFFECT: invention reduces mass and dimensions of antenna while maintaining strength and stability of its structure, as well as ease of manufacture.
