Abstract
The utility model relates to a high gain rotary TV aerial on balconies, which is composed of an aerial, a diverter, a mixer, an amplifier, an electric cable, etc. The aerial is inserted into a metal pipe from a parabolic-shaped bracket to form a reflector, a director is composed of two layers of metal pipes, and folded oscillators and oscillators receive U frequency band and V frequency band TV signals. The utility model is conveniently installed on balconies, directions for receiving television signals are adjustable through the diverter, and the gain input into the TV is high through the amplifier, the parabolic reflector and the director.
Description
The utility model relates to a kind of balcony formula high-gain and turns to television antenna, is applicable to the exterior aerial of making television receiver.
At present, the antenna that home-use TV machine adopts, kind is a lot, when distance TV station area far away, the effect of received television signal is relatively poor, and the antenna of outdoor dress generally all is the Yagi antenna or the fishbone antenna, because its volume is general bigger, relatively difficulty is installed, behind strong wind or sleet, damages easily, and the difficult aspect effect of adjusting is watched effect.
The purpose of this utility model provides a kind of can the installation easily on balcony, can receive V, U band TV signal, the direction high antenna of adjusting and gain.
The utility model is achieved like this: by antenna, steering gear 7, blender 10, amplifier 2 and cable 15,16 form, its antenna is that two Z-shaped supports 11 are fixed in support 4 terminal both sides, be inserted in 2 parabolical supports 12 in 2 Z-shaped supports, evenly insert 11 metal tubes 13 on 2 parabolical supports 12, middle metal tube 13 passes two Z-shaped supports 12 simultaneously, form a parabolic reflector, the front portion of support 4 is fixing each four metal tube 5 of symmetry up and down, as director, fix a folded dipole 8 at support 4 rear portions, oscillator 9 and blender 10, the TV signal that folded dipole 8 and oscillator 9 receive is mixed in blender 10, support 4 is fixed on the top of steering gear 7 and can rotates, arm 3 top stationary deflector 7, the bottom is amplifier 2 and fixed mount 1 fixedly, and the signal of blender is connected to by cable 15 and is connected to television set by cable 16 after amplifier 2 amplifies
This antenna can be installed on balcony easily by fixed mount 1, can receive V, U band TV signal by folded dipole 8 and oscillator 9, can adjust by steering gear 7 received television signal directions, through the gain height of amplifier 2 and paraboloidal reflector and the feasible input of director television set.
Below the utility model is further described below.
Accompanying drawing is a structure chart of the present utility model.
Metal tube 5,13 of the present utility model and oscillator 9 are for preventing that rainwater and foreign material from entering the inherent two ends of pipe and adding cover 14, metal tube 5 passes fixed block 6 back and passes through bolt up and down at support 4, insert in the hollow pipe of the power line of steering gear 7 by arm 3, the power line of amplifier 2 and steering gear 7 bottoms attached on the cable 16 together indoor by the control box supply power.By the reflector that parabolical support 11 is fixed, its focal plane is positioned on oscillator 9 and the folded dipole 8, and the TV signal of reception is enhanced.
