In order to achieve the above object, the small-sized medium wave radiating antenna of the utility model dual rotary face comprises and is installed in ground basis or is installed in firm banking on the building, is fixed on support column on basis or the base, is installed in flange and following radiation on the support column successively, is installed in down medium post on the radiation, is installed in last radiation on the medium post, is sleeved on loading coil and protective cover thereof on the medium post, is installed in ground antenna matching house, is installed in the impedance matching box and the two radiator that are connected with loading coil in the antenna matching house.Two radiator comprises the last radiator that is installed on the radiation upper flanges and is installed in down the following radiator on the end flanges under the radiation.That is to say that last radiator and following radiator have constituted the two radiator structure.
Radiator comprises that the many uniform metal radiant tubes and the binding that are fixed on the flange are fixed on the metallic support pipe between the metal radiant tube and enclose backguy.Metallic support pipe and enclose mechanical strength and the rigidity that backguy can be strengthened antenna radiator.
Radiator is a surfaces of revolution shape, and the shape of each the root metal radiant tube all rotation bus with this surfaces of revolution is identical.The rotation bus of the surfaces of revolution can be a kind of of straight line, circular arc line, semicircle, parabola or hyperbola.When the rotation bus was straight line, circular arc line, semicircle, parabola, hyperbola, ellipse respectively, the corresponding surfaces of revolution then was respectively taper seat, the playing surface of the table, hemisphere face, parabola, hyperboloid and ellipsoid.
Support column is made of metal tube or truss structure.
Symmetry is being fixed the wind resistance drag-line between last radiation and the ground, and the wind resistance drag-line is made of multistage steel wire rope and the insulator that is connected between the steel wire rope.Symmetry is being fixed wind resistance steel wire rope drag-line between following radiation and the ground.Wind resistance drag-line and wind resistance steel wire rope drag-line have been strengthened mechanical strength of the present utility model, have effectively avoided antenna to collapse, influence problems such as broadcast.
The medium post is made of the fiberglass or the high-frequency ceramic material of insulation and good mechanical property.Upper and lower radiation can be added lead and be constituted by metal tube, metal truss structure or carbon fibre pipe or dielectric post, pipe.
The lower edge of following radiator also can directly be dropped on the ground.Last radiator also can be spherical.Also can lay wire netting on the surface of upper and lower radiator.
The utility model size is little, in light weight, cost is low, installation is simple, and floor space is little, need not lay earth mat, can be erected in the service area even on the building.Its radiation efficiency height, stable performance is safeguarded simple.Can be widely used in the emission of medium wave wireless signal, be particularly suitable for the following middle low power transmitting station of 50KW.
