Abstract

The utility model relates to a backfire type receiving antenna for televisions, which comprises a metal rod used for support and fixation. A U-shaped hoop is clamped on the lower end of the metal rod, and U frequency vibrators are respectively fixed on the metal rod through a fixed mount and are sheathed in the middle part of the metal rod of which the top part is provided with a reflector. When the utility model receives a U channel, V frequency vibrators perform a function of the reflector; when the utility model receives a V channel, the U frequency vibrators and the reflector perform the function of a director; therefore, the utility model enhance the gain.

Description

The back reflection type reception antenna
The utility model relates to a kind of back reflection type reception antenna, and particularly used as television all-channel back reflection type reception antenna belongs to the television receiving antenna field.
Existing television receiving antenna generally all has director, and its director is towards TV station's direction, and range of receiving is narrower, and when especially receiving the far from the table signal, image is unintelligible.Advanced 001 and Nested-ring antenna are combined by three active dipoles, can not work in coordination when this antenna is worked, and can only singlely use, and more can not use as the all-channel reception antenna.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and provides a kind of range of receiving extensively, not to be with director, U, the V oscillator use that cooperatively interacts frequently, and reflector is towards the back reflection type reception antenna of TV station's direction.
The purpose of this utility model is achieved in that it comprises the Metallic rod of using as support fixation, and its structural feature is: u tie is connected to metal antenna bar lower end; Fixed mount is twisted the top that is connected on u tie, and V oscillator frequently is fixed on the fixed mount; The middle part of Metallic rod is with U oscillator frequently, and the top is equipped with reflector.U oscillator frequently is a circular metal ring.Reflector is circular aluminium sheet.
Compared to existing technology, the utlity model has following advantage:
1, range of receiving is wide, can clearly receive 400 kilometers programs with interior TV station.
2, because director is not set, so axially short, reception is equivalent to Unit 15-20.
3, U, V frequency oscillator reasonably makes up, and has improved gain.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The drawing explanation of accompanying drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model vertical view.
Fig. 3 is a V oscillator structural representation frequently.
Among the figure, Metallic rod (1), U-shaped clip (2), fixed mount (3,6,3), V be oscillator (4), U frequency oscillator (5), reflection (7), distributing point (9) frequently.
Metallic rod of the present utility model (1) adopts iron, and U-shaped clip (2) is connected to the bottom of Metallic rod (1).Fixed mount (3) adopts plastic products, is positioned at the top of U-shaped clip (2), twists with Metallic rod (1) to connect.Connect respectively on the fixed mount (3) and see V oscillator (4) frequently, the aluminum pipe of V oscillator (4) employing frequently φ 8-10mm, the long 480mm of aluminum pipe.V oscillator (4) frequently is position, 15 ° of angles with Metallic rod (1) respectively.Fixed mount (3) is apart from about U-shaped clip (2) 200mm.Fig. 3 is the U structural representation of oscillator (5) frequently, the aluminum annulus of U oscillator (5) employing frequently φ 8-10mm, and its distributing point (8) is fixed on the fixed mount (6), and draws wiring from distributing point (8), links to each other with television set.Fixed mount (6) also adopts plastic products.Fixed mount (6) is apart from about fixed mount (3) 280mm.Reflector (7) is arranged on the top of Metallic rod (1), apart from U frequency oscillator fixed mount (6) 260mm.Reflector (7) adopts the aluminium sheet compression moulding of thick 0.5mm, and diameter is 200mm, is a circular slab, and the centre is fixed on the top of Metallic rod (1) by fixed mount (8), and the diameter of reflector (7) is greater than the diameter of U frequency oscillator (5).
Operation principle of the present utility model is: the utility model is according to the backfire antenna principle design, and when receiving the U channel, V oscillator (5) frequently plays big reflector effect, when receiving the V channel, V oscillator (5), reflector (7) frequently plays the director effect, under their interaction, greatly improves gain.

Claims (3)

1, a kind of back reflection type reception antenna, it comprises the Metallic rod of using as support fixation, it is characterized in that:
A, u tie are connected to the Metallic rod lower end;
B, a fixed mount are twisted the top that is connected on u tie, and V oscillator frequently is fixed on the fixed mount;
The middle part of c, Metallic rod is with U oscillator frequently, and the top is equipped with reflector.
2, back reflection type reception antenna according to claim 1 is characterized in that U frequency oscillator is a circular metal ring.
3, back reflection type reception antenna according to claim 1 is characterized in that reflector is circular aluminium sheet.
