Problems solved by technology

[0002] At present, ordinary TV receiving antennas on the market, such as "Yagi antenna", are usually equipped with a reflector and an active vibrator on one end of the main crossbar, and several guide wires are installed at intervals in the horizontal direction on the other end of the main crossbar. The antenna with this structure, although the director brings a certain gain to the antenna and achieves a better bandwidth effect, but for TV users in marginal mountainous areas and rural towns, and in poor weather conditions and environments, The antenna is still weak when receiving TV signals

Embodiment Construction

[0010] The present invention will be further described below in conjunction with specific examples.

[0011] refer to figure 1 A reflector 1 is installed on one end of the main crossbar 4 of the TV receiving antenna, and the active vibrator 2 is installed on one end of the main crossbar 4 through the vibrator box 3 by means of two pairs of half-wave logarithmic antennas connected in parallel. On the horizontal direction of the other end of the cross bar 4, several main guides 7 are installed at intervals, and on the vertical direction of the other end of the main cross bar 4, several fixed brackets 5 are installed at intervals. On the rod 4 (the fixed support 5 can be folded on the main cross bar 4 by unscrewing the rotating shaft 9 during packaging, which is convenient for packaging, and the rotating shaft 9 can be tightened after opening the fixed support 4 during installation), on each fixed support 5 Several sub-directors 6 parallel to the main guide 7 are installed, wher...

Abstract

The invention relates to a television receiving antenna. Reflectors and active vibrators are installed at one end of a main cross rod of the antenna. Multiple main guiders are installed, in the horizontal direction, at the other end of the main cross rod at intervals. Multiple fixing supports are installed, in the vertical direction, at the other end of the main cross rod at intervals. Each fixing support is provided with multiple auxiliary guiders parallel to the main guiders. The position levels of the auxiliary guiders, on the same layer, on different fixing supports are consistent. By means of the television receiving antenna, the multiple layers of guiders in multiple units are additionally arranged in the horizontal direction of the main cross rod of the antenna, television signals are received in a stereoscopic mode, the actual test effect shows that under the general condition, gains can be increased by 0.2-0.5 db by each guider unit, and the bandwidth watching effect within the UHF frequency band range is effectively achieved.

Description

technical field [0001] The invention relates to a TV receiving antenna. Background technique [0002] At present, ordinary TV receiving antennas on the market, such as "Yagi antenna", are usually equipped with a reflector and an active vibrator on one end of the main crossbar, and several guide wires are installed at intervals in the horizontal direction on the other end of the main crossbar. The antenna with this structure, although the director brings a certain gain to the antenna and achieves a better bandwidth effect, but for TV users in marginal mountainous areas and rural towns, and in poor weather conditions and environments, The antenna is still weak when receiving TV signals. Contents of the invention [0003] The purpose of the present invention is to provide a TV receiving antenna which can enhance the gain of the antenna and has a good bandwidth viewing effect. [0004] The technical solution adopted by the present invention is: a TV receiving antenna, a refl...
