Abstract

The utility model relates to a novel all-channel TV receiving antenna composed of a supporter, a filter amplifier, a half-wave vibrator, an outer circular-ring oscillator, a vibrator for the high-frequency band and a signal power divider. Due to that formed by that two small circular rings are connected in parallel with each other, the receiving vibrator for the high-frequency band is arranged at the central position 5 cm to 9 cm away from a plane on which the outer circular-ring is arranged, the high-frequency receiving gain and the receiving capability of the novel all-channel TV receiving antenna are enhanced, and the performance of the whole antenna is improved.

Description

Novel full frequency road television receiving antenna

The utility model provides a kind of novel high section full channel tv receiving antenna, belongs to radiovision reception antenna field.

The utility model is the modified model to the patent No. 92230652.4 " Nested-ring antenna ", " Nested-ring antenna " is though overcome domestic TV reception antenna high directivity, few, the baroque problem of reception television channel in the past, but there are deficiency in high band, distance reception, and it is not enough to gain etc.

The purpose of this utility model is on the basis of former patent " Nested-ring antenna " high section oscillator to be improved, and improves the gain of high section oscillator, thereby improves the remote receiving ability of antenna.

The purpose of this utility model is achieved in that the novel full frequency road television receiving antenna of being made up of support, amplifier, half-wave dipole, outer toroid oscillator, high band oscillator etc., key is on the center on circle-ring vibrator plane outside the high band oscillator by two small circle ring parallel connections to be installed, outer toroid oscillator and high band oscillator all are installed in respectively on the support on top of half-wave dipole, on the support of half-wave dipole bottom filter amplifier is housed, the indoor signal power source distributor that is equipped with connects with cable between them.

Owing to adopted above-mentioned technical scheme, improved the receiving gain 1db of novel full frequency road television receiving antenna high band, strengthened remote receiving ability, improved the performance of entire antenna, very with practical value.

Below in conjunction with drawings and Examples the utility model is illustrated.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the utility model filter amplifier circuit theory diagrams.

Fig. 3 is the utility model signal power source allotter circuit schematic diagram.

Fig. 1 support, 2 filter amplifiers, 3 half-wave dipoles, 4 outer toroid oscillators, 5 high band oscillators, 6.7.8 geometrical clamp, 9 adaptations, 10 cables, 11 signal power source distributors, 12 feeder lines.

Figure 14 support (1) selects for use plastics or metal circular tube to make by the designing requirement size, be mainly used to fixedly oscillator etc., outer toroid oscillator (4) selects for use electrical conductivity is good, quality is light little pipe to make the opening annulus of 48 centimetres to 52 centimetres of diameters, rack-mount with geometrical clamp (7), mainly receive the TV signal of 6 to 12 channels; Half-wave dipole (3) is made basic half-wave dipole or folded dipole with the material of outer toroid, is installed on the support of outer toroid oscillator bottom with geometrical clamp (6), is used for receiving the TV signal of 1 to 5 channel; High band oscillator (5) is made the oscillator of two small circle ring parallel connections with the material of outer toroid, the diameter of each small circle ring is 16 centimetres to 20 centimetres, be installed on the center of outer toroid surface of oscillator with geometrical clamp (8), require 5 centimetres to 9 centimetres of the plan ranges of the plane of small circle ring oscillator in parallel and outer toroid oscillator, be mainly used to receive the TV signal of 13 to 54 channels; Filter amplifier (2) is selected former " Nested-ring antenna " filter amplifier for use, adopt 1: 1 adaptation between filter amplifier input and three sections oscillators, signal power source distributor (11) is selected " Nested-ring antenna " signal power source distributor for use, uses feeder line (small diameter coaxial cable) (12) to be connected respectively between filter amplifier and signal power source distributor and the television set.
