Abstract
The utility model relates to an all direction and turning combination type TV antenna. An upper-layer TV antenna 1 and a middle-layer TV antenna 2 are respectively fixed on the support rod 4. A shaft sleeve 5 is sheathed on the support rod 4. A lower-layer TV antenna 3 is fixed on the shaft sleeve 5. A gear II7 on the shaft sleeve 5 is engaged with a gear I 6 on a motor 8 which is fixed on the support rod 4.
Description
The utility model relates to omnidirectional and turns to the combination tv antenna technical field.
The present outdoor reception antenna of television set that uses is generally fixed, and the major defect of existence is: it is poor to the little receiving ability of angle to select, and makes TV receiving signal unintelligible few with platform that watch for a short time owing to can not rotate the reception coverage rate.
The purpose of this utility model is design a kind of omnidirectional and turn to the combination tv antenna, and it is made up of fixed antenna and rotable antenna two parts, makes that TV receiving signal is clear to be improved greatly with receiving ability.
The utility model is achieved in that is fixing upper strata television antenna 1 and middle level television antenna 2 respectively on the support bar 4, axle sleeve 5 is enclosed within on the support bar 4, be fixed with lower floor's television antenna 3 on the axle sleeve 5, the gear I6 engagement on gear II7 and the motor 8 is arranged on the axle sleeve 5, motor 8 is fixed on the support bar 4.
The utility model has the advantages that: but the all-channel received television signal, reasonable in design, low cost of manufacture, the clarity of signal that television set receives improves greatly.
Below in conjunction with accompanying drawing, the utility model is described further with embodiment:
Fig. 1 front view, the view of Fig. 2 for making progress at Figure 1A.
In the accompanying drawing: 1, upper strata television antenna, 2, the middle level television antenna, 3, lower floor's television antenna, 4, support bar, 5, axle sleeve, 6, gear I, 7, gear II, 8, motor.
After receiving TV signal by upper strata television antenna 1 and middle level television antenna 2, when the need optimum receiving signal, rotatable lower floor television antenna 3 selects phasing signals to improve video quality and antijamming capability.
