Embodiment
The utility model is described in further detail with reference to embodiment, but they are not to the utility model
The restriction of technical scheme, any conversion made based on the utility model training centre, all falls within the scope of protection of the utility model.
Refering to shown in Fig. 1-3, it is a kind of can two-way reception domestic aerial, including firm banking 1 and antenna body 2 are described
The top of firm banking 1 is provided with support bar 3, and the top of the support bar 3 is provided with bolt 4, the bolt 4 and support bar 3 one
It is body formed, cross bar 5 is provided with the antenna body 2, director 6 is fixedly installed successively on the cross bar 5 and uhf band shakes
Son 7, oscillator box 9 is provided with the cross bar 5, the oscillator box 9 is electrical connected with uhf band oscillator 7, and oscillator box 9 is to be used for
The device of impedance matching and signal gain amplification, longitudinally mounted through hole 10 is provided with the cross bar 5 and is transversely mounted through hole 11.
For the bolt 4 through through hole 11 is transversely mounted, the bolt 4, which passes to be transversely mounted on the part of through hole 11, is threaded with nut 8,
Antenna keeps state as shown in Figure 1.The bolt 4 passes through longitudinally mounted through hole 10, and the bolt 4 passes longitudinally mounted through hole 10
Nut 8 is threaded with part.Antenna keeps state as shown in Figure 2.Antenna can facilitate reception under Fig. 1 or Fig. 2 states
The digital television signal of horizontal polarization and vertical polarization.And due to eliminating reflector so that domestic aerial can be with two-way reception
Signal.
Operation principle：It is connected by bolt 4 with being transversely mounted through hole 11 or longitudinally mounted through hole 10 so that antenna body 2
Different angle is kept, facilitates the digital television signal for receiving horizontal polarization and vertical polarization.Due to eliminating reflector so that
Domestic aerial can be with two-way reception signal.
The beneficial effects of the utility model are：Due to eliminating reflector so that domestic aerial can be with two-way reception signal.
Due to being provided with firm banking, domestic aerial can be placed on smooth ground, keep stationary state.Due to being provided with transverse direction
Installation through-hole and longitudinally mounted through hole and bolt coordinate so that antenna body keeps different angle, facilitates reception horizontal polarization
With the digital television signal of vertical polarization.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any change or replacement expected without creative work, should all cover within the scope of protection of the utility model,
Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
