Abstract
The utility model relates to an all-channel receiving antenna, wherein an amplifier, a V1 vibrator, a V2 frequency vibrator and a U frequency vibrator are respectively fixed on a supporting rod by a fixed frame. The all-channel receiving antenna adopts a trapezoid vibrator as a 'U' frequency vibrator, thereby increasing receiving frequency band and gain. The all-channel receiving antenna has wide receiving range, clear image, simple structure and reasonable design.
Description
Technical field
The utility model relates to a kind of television set reception antenna, particularly a kind of all-channel reception antenna.
Background technology
Existing advanced television set reception antenna kind mostly is 001 type, overlaps models such as ring-like, such reception antenna, generally all can not comprehensive received signal in intensive " L " of signal section, range of receiving is narrower, and is when especially receiving the far from the table signal, not fogging clear, do not claim best all-channel reception antenna, people thirst for having range of receiving wide for this reason, bandwidth, and all-channel television antenna simple in structure occurs.
Summary of the invention
The purpose of this utility model is to provide that a kind of range of receiving is wide, bandwidth, simple in structure all-channel reception antenna.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of all-channel reception antenna, it is by fixed mount fixedly amplifier, V respectively
1Oscillator, V
2Frequently oscillator and U frequency oscillator is on support bar.
The beneficial effects of the utility model are:
1, adopts trapezoidal oscillator as " U " frequency oscillator, improved frequency acceptance band and gain.
2, range of receiving is wide, clear picture.
3, simple in structure, reasonable in design.
