Abstract
The utility model relates to a steering antenna; a cross rod of the steering antenna is arranged on a motor shaft of a motor and sheering drum; a U-section oscillator, a V-section oscillator and a guided wave tube are all arranged on the cross rod, the motor and sheering drum is arranged on a fixed rod, and a magnifier is arranged on the cross rod and positioned between the U-section oscillator and the V-section oscillator. In the steering antenna, an impedance adapter is arranged at the input ends of a U-section signal channel and a V-section signal channel of the magnifier, so that the impedance adapter can be directly connected with the V-section oscillator and the U-section oscillator, thereby saving a signal transmission line, reducing the loss of the original signals and improving the receiving effect of the antenna, meanwhile, the interference of the wave bands and the like caused by the winding together of the transmission line and the motor line in the antenna steering process can be prevented.
Description
Technical field
The utility model relates to a kind of position controlled rotary antenna.
Background technology
At present, the structure of position controlled rotary antenna normally is contained in motor and turns in the tube, and cross bar is installed on the motor shaft, and U section oscillator, V section oscillator, waveguide pipe are installed on the cross bar; Amplifier is installed on the fixed lever that turns to tube, and U section oscillator and V section oscillator are respectively drawn a signal transmssion line, together are connected in the amplifier with motor down-lead.When this position controlled rotary antenna was worked, U section oscillator and V section oscillator received TV signal, and to amplifier, because holding wire is long, meeting deamplification intensity influences reception through transmission line.
Summary of the invention
The purpose of this utility model provides a kind of position controlled rotary antenna that can increase reception.
The technical scheme that the utility model is taked is: a kind of position controlled rotary antenna, comprise motor and turn to tube, amplifier, V section oscillator, U section oscillator, waveguide pipe, cross bar and fixed lever, cross bar is located at motor and turns on the motor shaft of tube, and U section oscillator, V section oscillator, waveguide pipe are installed on the cross bar; Motor and turn to tube to be located at fixed lever is characterized in that amplifier is arranged on the cross bar, and between V section oscillator and U section oscillator.
Adopt the utility model, impedance matching box can be contained on the input of the U section of amplifier and V segment signal passage, directly link to each other with U section oscillator with V section oscillator, saved signal transmssion line, reduced the primary signal loss, improved the antenna reception, transmission line, motor lines are intertwined in the time of preventing simultaneously that antenna from turning to, and produce frequency range and phenomenon such as disturb mutually.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Sequence number is represented among the figure: motor and turn to tube 1, amplifier 2, V section oscillator 3, U section oscillator 4, waveguide pipe 5, cross bar 6, fixed lever 7 and motor shaft 8.
Embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
With reference to Fig. 1, this position controlled rotary antenna comprises motor and turns to tube 1, amplifier 2, V section oscillator 3, U section oscillator 4, waveguide pipe 5, cross bar 6 and fixed lever 7, cross bar 6 is located at motor and turns on the motor shaft 8 of tube 1, and U section oscillator 4, V section oscillator 3, waveguide pipe 5 are installed on the cross bar 6; Motor and turn to tube 1 to be located at fixed lever 7, amplifier 2 is arranged on the cross bar 6, and between V section oscillator 3 and U section oscillator 4.In above-mentioned, impedance matching box can be contained on the input of the U section of amplifier 2 and V segment signal passage, directly link to each other with U section oscillator 4 with V section oscillator 3, the signal that two frequency range oscillators receive amplifies the back directly to the television set end by amplifier, has removed signal transmssion line from the whole process, has reduced the loss of signal, guarantee primary signal intensity, reach the purpose that improves reception, transmission line, motor lines are intertwined in the time of preventing that antenna from turning to simultaneously, produce frequency range and phenomenon such as disturb mutually.
