Receive only earth satellite ground station

An earth satellite ground station having an antenna with a focal point, comprising,

• an antenna feed,
• a wave guide secured to and fed from said feed,
• a low noise amplifier for receiving electromagnetic wave energy from said wave guide,
• a receiver for receiving signals from said low noise amplifier and producing IF signal,
• a demodulator for receiving and demodulating the IF signals,
• a signal processing circuit connected to receive demodulated signals from said receiver for separating audio and video signals,
• a head end modulator connected to receive audio and video signals from said signal processing circuit,
• said head end modulator processing said audio and video signals for utilization directly by the audio and video circuits of a conventional television set,
• a plurality of circuit boards disclosed about said wave guide,
• said circuit board having components thereon defining said receiver, said demodulator, said signal processing circuit and said head end modulator,
• said antenna feed adapted to be located at the focal point of the antenna.
