Abstract

The utility model relates to an antenna device. A plurality of tube slots are arranged on an antenna amplifier box. Receiving oscillators of each channel are arranged on both ends of each tube slot, and purpose-made special clamps can not be used. Thus, the utility model saves labor and material, and reduces cost. A square lever is arranged on an antenna bracket, and a disc reflector is respectively arranged on both ends of the square level. Thus, contact is good and stable. A reflector composed of a disc and a plurality of bent pipes can be arranged on the antenna bracket. Thus, disc area is reduced, wind proof ability is increased, and sensitivity and anti-ghost image ability are improved. The utility model is suitable as an outdoor antenna of a TV.

Description

Antenna

The utility model relates to a kind of antenna assembly.

Existing exterior aerial, its each pick-up dipole is all rack-mount separately, clamps with special clip.Therefore each oscillator respectively has a wire to be welded in the clip, draws then with amplifier to link to each other, and needs special a plurality of special clips, and needs with electric wire manyly and grow, and the expense of taking a lot of work is expected.

Used reflector mainly is that a big disk is housed on support on the existing exterior aerial, perhaps make reflector with some aluminum pipes, the antenna that has only a disk reflector, in order to increase the ability of reflected signal, it is big that the diameter of its disk is wanted, so just make the capability of anti-wind of disk reflector poor, make the jitter of reflection.The reflector that has only some aluminum pipes, the area of its reflected signal is little, the ability of reflected signal.

The purpose of this utility model is: a kind of antenna is provided, makes it can increase wind loading rating, can increase sensitivity again, improve the anti-ghost image ability, and can not need special special clip, than existing antenna labor and material saving, reduce cost.

The purpose of this utility model is achieved in that on a kind of antenna assembly, on the amplification case of this antenna, has some roads tube seat, the pick-up dipole of each channel is installed from two of each road tube seat, and screw is fastening.The side's of being equipped with thick stick on antenna holder respectively is equipped with a disk reflector in two terminations of square thick stick.

On the support of the utility model antenna, also can be equipped with by a disk and the some reflectors that bend pipe combines.

Owing on antenna amplifier antennafire box of the present utility model, have tube seat, therefore the pick-up dipole of each channel just can directly be fixed in the tube seat from two, the a plurality of special clips that so just do not need fastening oscillator in the prior art, do not need the solder joint scolder in the clip yet, each oscillator directly links to each other with amplifier, only need a wire to draw from the amplifier box, labor and material saving so not only, reduce cost, and because the wire length minimizing, resistance is reduced, and received signal increases, and has more increased visual definition.

Because in the utility model antenna assembly, the reflector received signal that disk and bend pipe combine has been installed simultaneously, like this with have only disk or have only the existing antenna of bend pipe to compare, the disk area of used reflector just can reduce in the utility model device, the disk front also has bend pipe to support, and the wind loading rating of disk is strengthened, and disk and bend pipe reflector be reflected signal simultaneously, though thereby disk area reduced, the area of reflected signal does not reduce.The reflector of disk and bend pipe combination increases the sensitivity of reflection, has improved the ability of anti-ghost image, and has made the profile of antenna more attractive in appearance.

Connect two disk reflectors with square thick stick support in the utility model device, it is good, stable that comparable pipe connects more contact.

Below in conjunction with drawings and Examples the utility model is further specified

Fig. 1 is the structure embodiment stereogram of this real new antenna

Fig. 2 is the enforcement illustration of the novel middle amplifier box of this reality

Among the figure, 1,3,7. support 2,5. pick-up dipole 4. side's thick sticks 6. amplifiers 8,9. bend pipe reflector 10,12. disk reflectors 11. directors 13. tube seats

Figure 1 shows that an embodiment of the utility model antenna assembly.This antenna assembly is in support 1 upper edge holder orientation one antenna amplifier antennafire 6 vertically to be installed, and the back side of amplifier box has some roads recessed tube seat 13 in box in the present embodiment, as shown in Figure 2.The aluminum pipe pick-up dipole 2 of 1-5 channel and the aluminum pipe pick-up dipole 5 of 6-12 channel respectively are housed from two of tube seat.As cutting off in the middle of each tube seat, then the oscillator of installing from two does not contact mutually.If do not separate in the middle of the tube seat, the oscillator that two is installed does not contact mutually, and with screw that oscillator is fastening by screw.

Be vertically installed with support 3 and support 7 on support 1, square thick stick 4 is installed in an end of support 3, and a disk reflector 12 respectively is equipped with in two terminations of square thick stick 4.End at support 7 is equipped with disk reflector 10 and two bend pipe reflectors 8,9, at the other end of support 7 some directors 11 is housed, to improve the sensitivity of signal.

The utility model is applicable to the exterior aerial of television set.
