ABSTRACT OF THE DISCLOSURE A device for adjusting the orientation of an antenna for an earth station. A received signal coming in through the antenna is delivered from an outdoor unit to a demodulator of an indoor unit to be demodulated thereby. In the indoor unit, a converter receives an automatic gain controlled voltage signal from the demodulator and converts it into a digital signal, and a controller converts the digital signal into a predetermined control signal to feed it to the outdoor unit over the cable. In the outdoor unit, a display responsive to the control signal indicates a particular level which corresponds to the automatic gain controlled voltage. A person, therefore, can adjust the antenna to an optimum orientation unassisted, i. e., while observing the display.
