Abstract
The utility model relates to a very high frequency (UHF) TV receiving antenna composed of directors and folding vibrators which are installed on an antenna support. The utility model is characterized in that the three folding vibrators and the three directors form three two-unit receiving arms at an included angle of 120 DEG. The best preferred shape of the folding vibrator and the director is an arc shape, and the top of the arc is arranged against a center bearing bracket of the antenna. With small blind zone and strong anti-interference ability, the receiving antenna has the receiving effect superior than the existing antenna.
Description
The utility model relates to television receiving antenna, particularly is the super high band television receiving antenna.
Existing television receiving antenna pattern is various, and performance is different, but ability to accept is unsatisfactory, and the blind area is big when particularly receiving super high band (UHF) signal, and poor anti jamming capability directly influences the view reception effect of television set.
The purpose of this utility model is exactly that the super high band that a kind of blind area is little, antijamming capability is strong (UHF) television receiving antenna will be provided.
For finishing super high band (UHF) television receiving antenna that goal of the invention designs, form by the folded dipole and the director that are installed on the antenna holder, folded dipole and director respectively are three, Unit two of forming three horizontal sextant angles and being 120 ° receive arm, and three folded dipoles be the feed oscillator of parallel connection.
The utility model super high band (UHF) television receiving antenna blind area is little, antijamming capability strong, view reception effect is better than existing reception antenna.
As most preferred embodiment of the present utility model, the folded dipole and the director of reception antenna are circular arc, and arc pushes up back to the center of antenna support.Like this, can shorten three distances between the folded dipole fixing point, make antenna more firm, reception is better.
Embodiment describes the utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model most preferred embodiment schematic diagram.
As shown in Figure 1, the utility model super high band (UHF) television receiving antenna is made up of three two unit reception arms 4 that are installed on the antenna holder 1, the horizontal sextant angle that three two unit receive between the arm 4 is 120 °, director 3 and folded dipole 2 that Unit two receive on the arm 4 are circular arc, and arc pushes up back to center of antenna support 1.
Claims (2)
1, super high band television receiving antenna, form by the folded dipole and the director that are installed on the antenna holder, it is characterized in that said folded dipole and director respectively are three, Unit two of forming three horizontal sextant angles and being 120 ° receive arm, and three folded dipoles be the feed oscillator of parallel connection.
2, super high band television receiving antenna according to claim 1 is characterized in that said folded dipole is circular arc, and arc pushes up back to the center of antenna support.
