FIELD: antenna engineering; television, corporate, departmental, and radiophone public communication systems. ^ SUBSTANCE: proposed antenna assembly has two simultaneously operating electric dipoles inclined through angle of up to 15 - 20 deg. to rear wall of reflector. The latter is made in the form of cylindrical surface with lengthwise cut generating part. Electric dipoles are disposed in vertical symmetry plane (E plane) in immediate proximity of reflector rear wall symmetrically relative to horizontal symmetry plane (H plane). ^ EFFECT: reduced size of antenna toward radiation; extended operating band when using more broadband excitation sources. ^ 1 cl, 2 dwg
