Abstract
The utility model relates to a high-gain receiving antenna of a satellite television which is composed of a microwave parabolic reflecting plate, a universal fixed supporter, a fixed clamping plate, and a feeding source fixed supporter, wherein, the universal fixed supporter is arranged on the fixed clamping plate tightly and fixedly provided with the microwave parabolic reflecting plate which is provided with the feeding source fixed supporter. To receive signals, the feeding source fixed supporter is fixed in the focal position of the microwave parabolic reflecting plate. The device is suitable for users in both rural and urban areas.
Description
The utility model relates to a kind of high-gain satellite television receiving antenna, belongs to the commercial satellite television receiving antenna system.
At present, satellite earth antenna for household use is outdoor unit, generally is erected at civilian roof.Both dangerous, inconvenient again, and reception antenna itself is very heavy, wind loading rating is low, and its orientation height, the angle of pitch are difficult for adjusting, and erection method is disorderly and unsystematic, and is neither attractive in appearance, influences city appearance environment again.
The purpose of this utility model is to be to overcome above-mentioned weak point of the prior art, provides a kind of satellite fix accurate, and gain is high, the azimuth, and the pitch position adjustment is flexible, high-gain satellite television receiving antenna elegant in appearance.
The purpose of this utility model is achieved in that it comprises reception microwave parabolic shape reflecting plate, universal fixed mount, strap, feed fixed support, its special character is that strap is arranged on the balcony of building or the appropriate location of dwelling house, on strap, be fixed with universal fixed support, be fixed with the parabolic shape reflecting plate on the universal fixed support, fixing feed fixed support on the parabolic shape reflecting plate.For the ease of reaching the purpose of high-gain, the feed fixed support is fixed on the focal position of parabolic reflecting plate.
Compared to existing technology, the utlity model has following advantage:
1, satellite fix is accurate, adjusts the position of azimuth, the angle of pitch simply, can especially adapt to 87 ° of E stars of China spectators rating to satelloid, 110.5 ° of E stars, 105.5 ° of E magnitudes;
2, can become good family expenses satellite television receiving system with any tuner (C, KV wave band), satellite television receiver and the combination of family expenses color television set;
3, good rigidly draws wind-force strong, and general force 10 wind is following can operate as normal.
The drawing explanation of accompanying drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is the syndeton schematic diagram of the utility model and tuner, satellite TV set, color television set.
Embodiment describes the utility model in detail below in conjunction with (accompanying drawing).
Strap (9) adopts steel plate, and the front end of strap (9) has two screws (5,8), and two set bolts (6,7) insert in respectively and are used in the screw (5,8) and balcony or attachment fixed installation.The front end of strap (9) has fixing hole (4), universal fixed support (3) is fixed on the strap (9) by fixing hole (4), the other end passes through fixedly parabolic shape reflecting plate (2) of screw (11), the initial point place of parabolic shape reflecting plate (2) has universal fixed support screw (10), be used for fixing feed fixed support (1), feed fixed support (1) just in time is fixed on the focal position of parabolic shape reflecting plate.
Adjustment process of the present utility model is: at first give and put the azimuth and the angle of pitch, its best angle can check in from data or calculate with rectangular coordinate surface equation formula.The universal fixed support of coarse adjustment (3) makes the antenna alignment satellite then.The fine tuning of starting shooting is afterwards given receiver and is put receiving channels, adjusts universal fixed support (3) repeatedly, promptly adjusts the antenna azimuth and the angle of pitch repeatedly, makes clear image, and the ripple of making an uproar is little.If still fall flat, then can further adjust feed fixed support (1), feed fixed support (1) is fixed on the focus of parabolic reflecting plate (2) exactly.
Claims (2)
1, a kind of high-gain satellite television receiving antenna, comprise reception microwave parabolic shape reflecting plate, universal fixed support, strap, feed fixed support, it is characterized in that: on strap, be fixed with universal fixed support, be fixed with on the universal fixed support on parabolic shape reflecting plate, the parabolic shape reflecting plate and be fixed with the feed fixed support.
2, high-gain satellite television receiving antenna according to claim 1 is characterized in that the feed fixed support is fixed on the focal position of parabolic reflecting plate.
