Antenna rotator (1)

This circuit is used for CDE TR-44 antenna control, which uses a low voltage AC motor with a potentiometer display. The circuit eliminates the need to control the position until the antenna reaches the desired orientation. Using a 12VDC 1000Ω 1A relay, the TISN7274IL op amp U1 and a 360° rotary potentiometer R7 operating under 14V regulation of the original control.
