Title: Bs tuner
Inventor: SAKAMOTO KAZUAKI
IPC: H04B1/16
Filed: 1988-12-20
Abstract: PURPOSE:To easily perform the installation and the adjustment of a BS antenna single-handedly without necessitating any special apparatus by providing a VCO which inputs AGC voltage and generates variable frequency to vary according to its voltage level. CONSTITUTION:When the BS antenna is installed temporarily, and a first IF signal from a BS converter is fetched into an input terminal 1, the AGC voltage outputted from an AMP 9 has a charecteristic shown in a figure, and it becomes a larger voltage value according as an input signal level is larger. Accordingly, if this AGC voltage is inputted to the VCO 10, the audible signal of higher frequency is generated according as the input signal level is larger. Therefore, if a switch 11 is switched previously to a side shown by a broken line, an AGC sound to be generated in the VCO 10 comes to be reproduced from the speaker of a television monitor. Accordingly, if each of the elevation angle and the azimuth of the BS antenna is adjusted so that the generated frequency of the VCO 10 becomes highest, the proper elevation angle and the proper azimuth angle can be set.
