Abstract
The utility model relates to a simple full-frequency channel TV aerial which belongs to the field of a wireless aerial. Because of the adoption of an 8-shaped double-ring oscillator and a triangular oscillator, the utility model has the advantages of high receiving sensitivity, large covering area of a receiving angle and obvious gain enhancement, and in addition, because of the improvement for a resonance trap circuit of a frequency mixer, the utility model effectively prevents the mutual interference of high, middle and low frequency channels, further enhances gain and sensitivity and has enhancement of anti-interference performance. The utility model has the advantages of reasonable structure, simple production, raw material saving and good anti-wind and anti-aging performance.
Description
The utility model relates to a kind of simple and easy all-channel outdoor television receiving antenna, belongs to the wireless aerial field.
Current, antenna system popular on the China market is various, and the antenna structure complexity that has, debugging bother, involve great expense; The antenna directivity that has is strong, gain is low; Popular in recent years " 001 " antenna, amplifier antennas such as Nested-ring antenna all are significantly improved at frequency band, gain aspects, but the self-excitation of the type antenna close-table, cost height, weakness such as fragile very are difficult to resolve and determine.Especially in recent years China various places, city, county TV station are on the increase (many townshiies, town have newly established TV and plugged in turntable), and power is increasing, thereby, each department TV signal, reception ground field intensity, all change taking place, the weakness of above-mentioned antenna is also more and more obvious.
The utility model is a kind of in the area use of strong signal, the receive frequency good evenness, and highly sensitive, the receiving angle coverage is big, simply constructed a kind of family expenses all-channel television antenna.
The utility model is by figure of eight dicyclo oscillator (1) triangle oscillator (2) half-wave dipole (3) oscillator support (4) (5) (6) antenna holder (7) frequency mixer (8) lead-out wire (9), and line (10) is formed.Figure of eight dicyclo oscillator selects for use diameter 8-12mm tube and pipe of aluminium alloy to be welded into the figure of eight oscillator of opening 4cm, is fixed on the oscillator support (4); Make two of the triangle oscillators of the two long 35cm of waist, bottom side length 20cm with same material 90cm, be fixed on the oscillator support (5); Half-wave dipole is selected above-mentioned material 90cm * 2 straight lines for use, is installed on the oscillator support (6), adopts 1: 1 symmetrical and asymmetric variation adaptation of 75 Ω; Frequency mixer (8) is the buffer circuit between each oscillator, is actually the resonant trap circuit that L, C form, and purpose is to prevent the mutual interference of high, medium and low channel signals phase, is fixed on the antenna holder of half-wave dipole below; Antenna holder (7) is selected the high-quality plastics pipe for use by designing requirement; Oscillator support (4) (5) (6) is selected the high-quality plastics injection mo(u)lding for use, is fixed on the antenna holder to install and fix each oscillator by designing requirement; Lead-out wire (9) is selected the some rice of 75 Ω high-quality coaxial cables for use, is drawn by mixer output signal is imported television set.
The figure of eight oscillator ratio of gains half-wave dipole that the utility model antenna is adopted improves 2db, and 13-56 channel effects are obviously improved.The ratio of gains half-wave dipole of triangle oscillator improves 1.5db, and wide, novel in design, handsome in appearance, simple in structure, cheap, the windproof anti ageing property of entire antenna receiving pattern is good.
Figure of description:
Fig. 1: be the antenna schematic diagram: figure of eight oscillator (1), triangle oscillator (2), half-wave dipole (3), oscillator support (4) (5) (6), antenna holder (7), frequency mixer (8), lead-out wire (9), line (10).
Fig. 2: be mixer line figure.
Claims (2)
1. simple and easy all-channel television antenna, by figure of eight dicyclo oscillator (1), triangle oscillator (2), half-wave dipole (3), oscillator support (4), (5), (6), frequency mixer compositions such as (8), it is characterized in that figure of eight dicyclo oscillator on top, the triangle oscillator is in the centre, and the bottom is a half-wave dipole, foot is equipped with frequency mixer, is separately fixed on the antenna holder.
2. antenna according to claim 1 is characterized in that frequency mixer is L, the resonant trap circuit that C forms.
