ABSTRACT

The main function of High Power Transmitting station is that, it downlinks the signals from the satellite with the help of a parabolic dish antenna and boosts the signal in such a manner that it is suitable for a good TV reception & transmission.

The parabolic dish antenna is placed in such a manner that its elevation and azimuth is calculated according to the looking angle of the satellite. Here two signals are to be transmitted i.e. audio signal & video signal. Modulation is required for these signal where AM is used for video signal & FM is used for audio signal.

The amplification of the signals is done by power amplifiers. The audio signal is boosted to 1 kw & video to 10kw and sent to the duplexer. These signals are fed to the turnstile antenna with the help of coaxial cables which inturn transmitted to various places around 120 km.
