Abstract
A receive only, low cost, small size, frequency agile earth satellite ground station has the low noise amplifier, frequency agile receiver, head end modulator, motor control circuit and optional signal unscrambler disposed on circuit boards about a variable polarization antenna-to-low noise amplifier feed which together with the motor for controlling the feed polarization of the feed are all located in a weather insulating cannister at the focal point of the system antenna whereby the only elements of the system not located in the cannister are the antenna and a cable connected control console employed to select a desired channel and to select local or satellite reception located at the TV set. A motor control is provided which senses odd-or-even least significant bit of binary coded channel selection signals to determine if the feed polarization, control motor must be energized.
